TL;DR

A good apraxia of speech goal bank organizes targets by motor speech difficulty level: CV and VC syllables first, then CVCV, then multisyllabic words and phrases. Goals should name the stimulus type, accuracy threshold, number of trials, and cuing level. ASHA recommends motor-learning principles (high repetition, variable practice, reduced cues over time) as the evidence base for CAS treatment.

Speech goals for childhood apraxia need to be sorted by motor difficulty, not by whatever sound comes next on a standard developmental chart. Childhood apraxia of speech (CAS) is a motor speech disorder: the brain has trouble planning and programming the precise movements the mouth needs to make speech happen. That's different from an articulation disorder, where a child just swaps one sound for another, and different again from a language delay, where the main gap is vocabulary or grammar.

Because the deficit is motor rather than phonological, goals need to reflect motor learning principles instead of something generic like "produce /s/ correctly in 80% of opportunities." A goal bank built for articulation won't serve a child with CAS well. You need targets organized by syllable shape complexity, cuing hierarchy, and the conditions that actually promote motor learning: lots of repetition within a session, a mix of blocked and variable practice, and cues that get systematically pulled back as accuracy improves.

ASHA's technical report on CAS lists three core diagnostic features: inconsistent errors on consonants and vowels, lengthened and disrupted transitions between sounds, and off prosody [1]. Goals that skip over these, especially vowels and prosody, were probably lifted from an articulation goal bank and will miss real therapy targets.

The goal bank here runs in tiers. Tier 1 covers the simplest syllable shapes (CV, VC). Tier 2 covers CVCV and reduplicated forms. Tier 3 covers multisyllabic words. Tier 4 covers phrases and sentences with proper prosody. Most kids with CAS start at Tier 1 or 2 no matter their age, because motor speech therapy meets the motor system where it actually is, not where the child "should" be for their age.

What a well-written CAS goal actually contains

A solid goal has four parts: the condition (what stimulus, what cuing level), the target behavior, the accuracy criterion, and how progress gets measured. Something like "will improve speech intelligibility" can't be measured and won't guide treatment decisions.

A useful template: "Given [cuing level] for [syllable shape or word set], [child's name] will produce [target] with [X]% accuracy across [Y] consecutive sessions as measured by [SLP observation / recorded probes]."

The cuing level does most of the work in a CAS goal. Kids with CAS usually need heavy cuing early on, so the goal should say whether you're working with maximum cuing (simultaneous modeling, tactile cues, slow rate), moderate cuing (immediate imitation), or minimal cuing (delayed imitation or spontaneous speech). Across a treatment arc, you write a sequence of goals that gradually pull that cuing back. That reduction is the evidence that motor learning is actually taking hold.

Accuracy thresholds in CAS goals often start lower than what you'd see in articulation goals, sometimes 70 to 80% at the most supported cuing level, then 80 to 90% independently before moving to a harder syllable shape. Requiring 90% accuracy with maximum cuing before advancing can stall progress by keeping a child drilling too long. Motor learning research (Schmidt & Lee, Motor Control and Learning, 6th ed.) suggests some variability during acquisition is actually healthy: you want a consistent upward trend, not perfection [12].

If you're heading into speech therapy with a licensed SLP, having these goal components spelled out before the IEP meeting means you won't be stuck accepting a boilerplate goal that's nearly impossible to track.

Tier 1: CV, VC, and CVC syllable shapes

These are the building blocks. A child who can't yet produce consistent CV syllables needs to work here first, whatever their age.

Sample goals: given simultaneous modeling (maximum cuing), the child will produce CV targets ("go," "no," "me," "bye") with 80% accuracy across 3 consecutive sessions of at least 20 trials each, measured by SLP probe data. Given immediate imitation (moderate cuing), the child will produce CV targets from a 10-word functional vocabulary set with 80% accuracy across 3 consecutive sessions, measured by recorded probes. Given delayed imitation (minimal cuing), the child will produce VC targets ("up," "on," "eat") with 80% accuracy across 3 consecutive sessions of 20 trials. Given immediate imitation, the child will produce CVC words with early-developing consonants (nasals, stops, glides) and accurate vowels in 75% of trials across 3 consecutive sessions. And given maximum cuing with visual and tactile support, the child will show reduced vowel distortion on CV and CVC targets, hitting correct vowel identity in at least 70% of trials across 4 sessions.

A note on vowels: many articulation goal banks never mention them, but CAS goals should. Vowel errors are a hallmark of CAS [1], and skipping them means skipping a real diagnostic and treatment priority.

Tier 2: CVCV, reduplications, and two-syllable words

Once a child hits Tier 1 targets at the minimal cuing level, it's time for two-syllable shapes. Reduplicated forms ("mama," "dada," "bye-bye") are usually the natural bridge, since the motor plan repeats rather than changing for each syllable.

Sample goals: given immediate imitation, the child will produce reduplicated CVCV words ("mama," "bye-bye," "no-no") with 80% accuracy across 3 consecutive sessions of 20 trials each. Given immediate imitation, the child will produce varied CVCV words ("baby," "cookie," "doggy") with 75% accuracy across 3 consecutive sessions. Given minimal cuing (spontaneous or self-initiated speech), the child will produce a 5-word functional CVCV vocabulary with 80% accuracy across 3 sessions in at least two settings. Given immediate imitation with visual cuing, the child will produce two-syllable words with correct lexical stress in 70% of trials across 4 consecutive sessions. And given a structured play routine with moderate cuing, the child will produce two-syllable functional words to request or comment with 75% accuracy across 3 sessions.

The stress goal often gets dropped from CAS goal banks because it's harder to measure, but inappropriate stress is a core diagnostic marker [1]. Skip it, and you may end up with a child who nails words in isolation but sounds robotic or hard to follow once he's talking in sentences.

Tier 3: multisyllabic words and clusters

Moving to three- and four-syllable words is a big jump in motor planning. Some children with more severe CAS stay at Tier 2 for a long stretch before getting here, and that's fine. Rushing to multisyllabic targets before the lower tiers are solid tends to produce compensatory strategies and inconsistent errors that are hard to undo later.

Sample goals: given immediate imitation, the child will produce three-syllable words ("banana," "computer," "umbrella") with 75% accuracy across 3 consecutive sessions of 20 trials. Given minimal cuing, the child will produce three-syllable words from a 10-word target set with 80% accuracy across 3 sessions. Given immediate imitation, the child will produce words with consonant clusters ("stop," "play," "friend") with 70% accuracy across 3 sessions. Given a delayed imitation condition, the child will produce multisyllabic words with correct syllable segregation (no added schwa between consonants) in 75% of trials across 4 sessions. And given minimal cuing in structured conversation, the child will produce a 10-word set of three-syllable functional vocabulary (chosen with the family) with 80% accuracy across 3 sessions in two different contexts.

For preschoolers, Tier 3 vocabulary should come from words they actually need at home and school. An SLP who lets the family help pick the target words usually sees much better carryover, since the child hears those words in real contexts every day. That matters most when you're writing goals for apraxia of speech preschool IEP targets.

Goal bank tier 4: phrase and sentence level goals with prosody

This is the tier where CAS therapy starts to look like real conversation. A child who can nail individual words but can't string them into a phrase still has a serious communication problem, and prosody, the rhythm and melody of speech, becomes the main target once you get here.

Sample goals at this level might include:

1. Given immediate imitation, [name] will produce two-word phrases (e.g., "more please," "go car") with accurate lexical stress and 80% word-level accuracy across 3 consecutive sessions.

2. Given moderate cuing in a structured activity, [name] will produce three-word phrases with 75% accuracy (scored at the phrase level, not word level) across 3 consecutive sessions.

3. Given minimal cuing in conversational exchange, [name] will produce functional two-to-three word phrases to make requests or comments with 70% accuracy across 3 sessions in at least two different settings.

4. Given a carrier phrase structure (e.g., "I want ___"), [name] will produce the complete phrase with appropriate sentence stress and natural rate in 75% of trials across 3 consecutive sessions.

5. Given spontaneous conversational opportunities, [name] will use three-word utterances with intelligible prosody (rated by an unfamiliar listener as "mostly understandable" on a 4-point scale) in 60% of sampled utterances across 3 sessions.

Goal 5's unfamiliar listener criterion matters because CAS hits intelligibility hardest with people outside the immediate family. A parent might understand every word while a teacher or classmate is lost. Measuring how a child comes across to someone who doesn't know them well is one of the functional outcome standards the Apraxia Kids organization highlights in its treatment resources [2].

What are good IEP goals for preschool children with CAS?

Good preschool goals for CAS pull off three things at once: they stay measurable, they tie into actual classroom participation, and they respect that this is a motor speech disorder rather than a simple sound-error problem. For a child between 3 and 5, the most useful targets are the words and phrases that let a child join the preschool day: calling a friend's name, asking for help, naming objects at circle time, commenting during play.

How motorically complex those targets are depends on the child, so you choose the syllable shape tier that matches where they currently sit. Three sample preschool IEP goals:

1. Given immediate imitation during structured preschool routines, [name] will produce a 10-word core vocabulary set (CV and CVC targets selected from classroom vocabulary) with 80% accuracy across 3 consecutive therapy sessions, as measured by SLP probe data.

2. Given moderate cuing, [name] will produce two-word requesting phrases ("I want ____") with at least the carrier phrase produced intelligibly in 75% of opportunities across 3 sessions in the preschool setting.

3. Given minimal cuing and natural classroom contexts, [name] will spontaneously use at least 5 functional single words or phrases to communicate with peers or teachers across 3 consecutive 30-minute classroom observation periods, as measured by frequency count.

Starting early counts for a lot with CAS. Children's brains have the greatest capacity for motor learning early on, and research on starting therapy young consistently shows better long-term outcomes when treatment begins before age 5 [3]. Under IDEA Part C (birth to 3) and Part B (ages 3 to 21), children with a diagnosed motor speech disorder qualify for speech-language services in the public school or early intervention system at no cost to families [4]. ASHA's Practice Portal on CAS states that treatment should follow motor learning principles, specifically high practice intensity, knowledge of results, and distributed versus blocked practice schedules [1]. IEP goals that skip these principles are really articulation goals with a CAS label stuck on them, and that mismatch shows up in slow progress.

How many trials per session does a child with CAS need?

More than most SLPs typically run. That's the short answer from motor learning research, and it tends to surprise families when they hear it.

Dynamic Temporal and Tactile Cueing (DTTC), one of the most researched CAS treatments, uses high-intensity practice, with some protocols calling for 100 or more productions of a target per session [5]. The Nuffield Dyspraxia Programme and ReST (Rapid Syllable Transition Treatment) also build high repetition in as a core piece. A 2015 randomized controlled trial by Murray, McCabe, and Ballard, published in the Journal of Speech, Language, and Hearing Research, found ReST produced significant gains at a treatment intensity of 4 sessions per week for 3 weeks [6].

A child getting one 30-minute session a week at school simply cannot reach that intensity through therapy time alone. That's the real reason home practice isn't optional for CAS: goals should ideally build in a home practice component, or at the very least the IEP should note that a home program will be provided.

Apps and tech tools that offer structured, repetitive practice with feedback can help close that gap between sessions. Little Words was built with exactly this in mind, giving parents motor-speech-informed practice routines to run at home. It won't replace a skilled SLP, but it can meaningfully add to the number of repetitions a child gets in a week.

You can also write intensity directly into a goal: something like "across 3 consecutive sessions of at least 50 trials each" keeps whoever delivers the therapy honest about actual dosage.

How do you track progress on CAS goals?

Two tools do most of the work here: probe data and language samples. Probe data is usually the primary measure for CAS. You present target words in a standardized way (imitated or spontaneous), record the response, and score it.

Scoring options include:

For very young children or kids with severe CAS, whole-word accuracy can be discouraging, since it demands every part of the word be correct at once. A child might score zero words while still making real gains on individual features. In those cases, tracking vowels and stress separately gives a truer picture of what's actually improving.

The Apraxia Kids website offers free probe word lists and recording forms for SLPs and families [2]. The Diagnostic Evaluation of Articulation and Phonology (DEAP) and the Kaufman Speech Praxis Test (KSPT) are standardized tools with syllable shape hierarchies that can inform baseline data for goal writing, though neither is meant for ongoing progress monitoring on its own.

One approach that works well in practice: run a 20-item probe every 5 to 6 sessions, record it, and score it against the criteria in the goal. Graphing that data over time is good clinical practice, and it's also something you can show families and bring to IEP meetings.

Is CAS different from autism-related speech difficulties, and do the goals differ?

CAS and autism overlap often. A 2015 study estimated CAS occurs in roughly 65% of minimally verbal children with autism, compared to about 1 to 2 per 1000 in the general population [7]. But CAS shows up plenty in children with no autism diagnosis and no other developmental differences at all.

When the two co-occur, the motor speech goals themselves don't really change, since the motor planning deficit behind CAS is the same no matter what else a child is diagnosed with. You still move through the syllable shape hierarchy, still apply motor learning principles, still fade cuing systematically. What shifts is how you set up the therapy environment, the reinforcement system, and the social context of practice to fit that child.

For minimally verbal children with autism who also have CAS, a real question comes up: whether to target verbal speech, AAC devices, or both together. Current speech-language research holds that AAC doesn't suppress verbal speech development and may actually support it by cutting down communicative frustration [8]. So goals for a child with both CAS and autism can run in parallel, motor speech goals for verbal production alongside AAC goals for independent functional communication.

The autism spectrum speech therapy page goes deeper into communication goal frameworks for autistic children, and if you're working with a child whose speech leans heavily on echoed language, the echolalia and echolalia meaning articles are worth reading alongside this one. Echolalic speech and CAS need different goal frameworks even when they look similar on the surface.

Four approaches currently have the strongest published evidence for CAS, and it matters which one your child's goals are built around, because the same-sounding goal can mean very different things depending on the method. DTTC (Dynamic Temporal and Tactile Cueing), developed by Strand and colleagues [9], uses a cueing hierarchy that moves from simultaneous production through imitation to spontaneous speech, so goals written for DTTC should spell out the cuing level explicitly. ReST (Rapid Syllable Transition Treatment), from Murray, McCabe, and Ballard [6], targets accurate production and smooth transitions between syllables using nonwords to keep things novel; goals here often target nonword probes, which sounds strange but has solid evidence behind it. NDP3 (Nuffield Dyspraxia Programme, 3rd edition) is a structured motor speech program widely used in the UK that builds systematically from sounds to words to phrases. And Integrated Phonological Awareness (IPA) addresses both motor speech and phonological awareness, since children with CAS often get limited practice with sound patterns and the two areas end up co-impaired; goals here combine motor speech targets with phonological awareness tasks. ASHA's Practice Portal summarizes the evidence behind each of these and is the most current free clinical resource available [1], and it also draws a clear line between CAS and other motor speech disorders, which is worth a look if you're not sure a child's profile actually fits CAS. For childhood apraxia of speech specifically, the Apraxia Kids treatment guidelines are the most detailed resource written for families and match up with ASHA's clinical recommendations [2]. Most school-based CAS goals get written once a year on the IEP, but progress should be checked far more often than that. IDEA requires progress reports at least as often as report cards go out [4], and many SLPs working with CAS review probe data every 6 to 10 sessions to decide whether a child should stay on a target or move up a tier. A child hitting 80% accuracy at minimal cuing across three consecutive sessions is ready to advance. One stuck below 60% for six sessions probably needs a different cuing approach, different targets, or a second look at whether CAS is even the right framework. Treat goal banks as a menu rather than a script: pick the tier and cuing level that fit the child right now, set a clear criterion for moving on, and decide ahead of time what comes next. Writing "when this goal is mastered, the team will move to [next goal]" directly into the IEP is completely legitimate and saves time at annual reviews. At home, five to ten minutes of daily practice beats one long weekly session, since motor learning responds to that kind of distributed repetition. It's worth tracking whether home practice is actually happening, too, because a child getting one 30-minute school session a week with nothing at home is getting a fraction of the dose the research was based on. A handful of free resources are genuinely worth knowing about, and it helps to know what each one actually gives you. Apraxia Kids is the most detailed nonprofit resource for CAS in the US, with treatment summaries, school tool kits, and a directory of SLPs trained in CAS; they don't publish a formal goal bank, but their treatment guidelines come closest [2]. The ASHA Practice Portal's CAS page is free to anyone, not just members, and covers diagnostic criteria, evidence summaries for each treatment approach, and frameworks for clinical decision-making [1]. Edythe Strand's published work on DTTC includes articles and some freely available materials describing how to implement the protocol and structure targets; searching "Strand DTTC protocol" on Google Scholar or PubMed will turn these up [9]. And several state education agencies, including California's and Minnesota's Departments of Education, publish free speech-language IEP goal banks, though quality for CAS specifically varies a lot and you'll need to adapt generic goals to fit the motor learning framework. If you're just entering the school system, the early intervention article walks through the federal eligibility rules and what the evaluation process looks like, and if you're weighing whether to add telehealth sessions alongside in-person therapy, the online speech therapy article covers what to expect and how to find providers with CAS experience. For a wider view of how therapy works once your child is school-age, beyond just the goals themselves, the speech therapy speech therapist article covers session structure, how often therapy should happen, and how to tell if an SLP is a good fit.

Frequently asked questions

What makes a CAS goal bank different from a regular articulation goal list

A goal bank for childhood apraxia of speech is a library of pre-written, measurable therapy goals organized by syllable shape complexity and cuing level. Because CAS is a motor speech disorder, the goals need to reflect how motor learning actually works: lots of repetition, a systematic cuing hierarchy, and progress criteria that capture prosody as well as accuracy. Generic articulation goal banks fall short here because they miss vowel errors, stress errors, and cuing altogether. That gap matters: articulation goals target sound-level accuracy ("produce /s/ correctly in 80% of words"), while CAS goals target motor planning at the syllable and word level, name the cuing condition, address vowels and prosody, and fade cuing over time as the child improves. Borrow an articulation framework for a child with CAS and you'll likely miss the disorder's core features and slow the child's progress. Those core features, according to ASHA, are inconsistent errors on consonants and vowels, lengthened or disrupted transitions between sounds and syllables, and prosody that's off in stress, rhythm, or intonation. Goals should address all three. It's common for SLPs to borrow goals that only track consonant production, which leaves vowel errors and prosody unmeasured entirely. Vowel errors in particular are a hallmark diagnostic feature of CAS, and clinicians trained mostly in articulation disorders often skip writing vowel goals simply because vowel errors are rare in that population. Tracking percent vowels correct separately from consonants gives a much clearer picture of motor speech progress, especially early on at Tier 1 and Tier 2.

Writing the goal itself

A workable template: "Given [cuing level], [name] will produce [syllable shape or word set] with [X]% accuracy across [Y] consecutive sessions of at least [Z] trials each, as measured by [SLP probe data or recorded sample]." The cuing level is what separates a CAS goal from an articulation goal, so be specific: simultaneous modeling, immediate imitation, delayed imitation, or spontaneous production. For preschoolers, target functional vocabulary the child actually needs in the classroom: requesting help, labeling objects, greeting peers. Match the syllable shape tier to the child's current motor level rather than their age; a 4-year-old at Tier 1 needs CV and CVC goals, not three-syllable words. Under IDEA Part B, children ages 3 to 5 with a motor speech disorder qualify for speech services at no cost through their school district, and that eligibility extends up to age 21. Children under 3 may qualify under IDEA Part C. Private insurance for outpatient therapy varies by plan and state, and while many states have autism insurance mandates that cover speech therapy, a CAS diagnosis alone doesn't trigger those mandates. On dosage: research-based treatments like DTTC and ReST use 50 to 100+ productions per session, far more than a typical 30-minute school session delivers. Home practice isn't optional here. Distributed daily practice of 5 to 10 minutes produces better motor learning outcomes than one longer weekly session on its own, so it's worth writing minimum trial counts into the goal itself (for example, "across sessions of at least 50 trials") to build dosage into the plan.

Tracking progress and knowing when to move on

The standard benchmark for advancing to the next tier is 80% accuracy at the minimal cuing level (delayed imitation or spontaneous production) across 3 consecutive sessions. Move up too early and the motor plan hasn't stabilized yet; stay too long at a mastered tier and you waste therapy time. Some SLPs write the advancement criterion directly into the IEP goal so the team isn't re-deciding it at every session. If a child is stuck on the same target after 6 to 10 sessions with no progress, a few things are usually at play: the cuing level may be too hard, the targets may be the wrong syllable shape tier, session dosage may be too low, or the diagnosis itself may need a second look. CAS is sometimes misdiagnosed, and a child who isn't responding to motor speech treatment may have a different profile altogether. Asking for a second opinion from an SLP with CAS specialty training is a reasonable step. Dynamic Temporal and Tactile Cueing (DTTC), developed by Edythe Strand, is one approach worth knowing by name here. It moves through a structured hierarchy from simultaneous production to spontaneous production, and goals written for it name the exact cuing level at which accuracy is measured. It's also one of the approaches with the strongest published evidence for CAS, according to ASHA's Practice Portal. For free tracking tools, Apraxia Kids offers probe word lists and some recording forms on their website, and ASHA's Practice Portal has free clinical guidance. Plenty of SLPs just build their own probe forms in a spreadsheet. What matters most is consistency: probe with the same word set and scoring criteria every time, record sessions when possible, and graph the data so trends are easy to see at IEP meetings.

Intelligibility and AAC

CAS reduces speech intelligibility significantly, especially with unfamiliar listeners, because the motor errors are inconsistent and hit both individual sounds and prosody. That makes intelligibility to unfamiliar listeners a legitimate functional goal at the phrase and sentence level, measurable by having someone unfamiliar to the child transcribe or rate a sample. A criterion like "rated as mostly intelligible by an unfamiliar listener in 60% of sampled utterances" works well because it's both measurable and functional. A child with CAS can also use AAC while working on verbal speech goals, and current evidence supports doing both at once. AAC doesn't suppress verbal speech development, and it can ease communicative frustration while motor speech skills are still building. For minimally verbal children with CAS, running AAC goals alongside motor speech goals is standard practice, and both ASHA and Apraxia Kids support this approach. Which AAC system to use should come down to the child's current motor and cognitive profile.

Here are the sources behind this piece: the ASHA Practice Portal: Childhood Apraxia of Speech lays out the three core diagnostic features of CAS and points to motor learning principles, high repetition, varied practice, and cues that fade over time, as the evidence base for treatment. Apraxia Kids: Treatment and School Resources treats intelligibility to an unfamiliar listener as the real measure of progress, and offers free probe word lists and school tool kits. The Centers for Disease Control and Prevention: Developmental Milestones and Early Intervention notes that starting intervention before age 5 tends to lead to better long-term outcomes for kids with communication disorders. On the legal side, the U.S. Department of Education: IDEA Individuals with Disabilities Education Act guarantees free speech-language services to children with a diagnosed motor speech disorder under Part C (birth to 3) and Part B (ages 3 to 21), with progress reports required at least as often as report cards go home. Two treatment studies are worth knowing about directly. Strand EA, Stoeckel R, Baas B. Treatment of severe childhood apraxia of speech: A treatment efficacy study. Journal of Medical Speech-Language Pathology. 2006. describes DTTC protocols that use high-intensity practice, sometimes 100 or more productions of a target per session, moving through a cueing hierarchy from simultaneous production down to spontaneous speech. Murray E, McCabe P, Ballard KJ. A randomized controlled trial for children with childhood apraxia of speech comparing Rapid Syllable Transition Treatment and the Nuffield Dyspraxia Programme. Journal of Speech, Language, and Hearing Research. 2015. found real gains from ReST delivered four sessions a week for three weeks, in a trial that compared it against NDP3. The mechanics of DTTC itself, including who developed it, are covered in Strand EA. Dynamic Temporal and Tactile Cueing: A Treatment Strategy for Childhood Apraxia of Speech. American Journal of Speech-Language Pathology. 2020., which credits Edythe Strand with building the structured cueing hierarchy at its core. On the autism connection, Tierney C, Mayes S, Lohs SR, et al. How valid is the checklist for autism spectrum disorder when a child has apraxia of speech? Journal of Developmental and Behavioral Pediatrics. 2015. found CAS in roughly 65% of minimally verbal children with autism, against a background rate of about 1 to 2 per 1000 in the general population. And for parents worried that AAC devices might delay talking, Millar DC, Light JC, Schlosser RW. The impact of augmentative and alternative communication intervention on the speech production of individuals with developmental disabilities: A research review. Journal of Speech, Language, and Hearing Research. 2006. found the opposite: AAC doesn't suppress verbal speech and may help it along, with 11 of 27 participants in the reviewed studies actually gaining speech production after starting AAC. The ASHA Technical Report: Childhood Apraxia of Speech (Ad Hoc Committee on Apraxia of Speech in Children). 2007. is where the formal definition comes from: inconsistent errors on consonants and vowels, lengthened and disrupted transitions between sounds, and prosody that doesn't fit. The American Academy of Pediatrics (HealthyChildren.org): Speech and Language Delays and Disorders backs early referral to a speech-language pathologist whenever a child's speech raises questions. And on the practice side, Schmidt RA, Lee TD. Motor Control and Learning: A Behavioral Emphasis. 6th ed. Human Kinetics. 2019. makes the point that some wobble during learning is normal and even healthy: the goal is a steady upward trend, not perfection, and practice spread out over time sticks better than practice crammed together.
