10-Minute Speech Practice That Doesn't Require Sitting Still

Last updated 2026-07-09

What is a goal bank for apraxia of speech, and why does CAS need its own?

A CAS goal bank sorts speech targets by motor difficulty, not by which sound comes next in a developmental chart. Childhood apraxia of speech (CAS) is a motor speech disorder. The child's brain has difficulty planning and programming the precise movements the mouth needs to produce speech. That is categorically different from an articulation disorder, where a child simply substitutes one sound for another, and it is different from a language delay, where vocabulary or grammar is the primary gap.

Because the deficit is motor, not phonological, the goals need to reflect motor learning principles rather than just "produce /s/ correctly in 80% of opportunities." A goal bank built for articulation will not work well for CAS. You need targets organized by syllable shape complexity, cuing hierarchy, and the conditions that promote motor learning: high repetition of targets within a session, a mix of blocked and variable practice, and systematic fading of cues as accuracy improves.

ASHA's technical report on CAS describes the three core diagnostic features: inconsistent errors on consonants and vowels, lengthened and disrupted coarticulatory transitions, and inappropriate prosody ^[1]. Goals that ignore these features, especially vowel errors and prosody, are probably borrowed from an articulation goal bank and will miss important therapy targets.

The goal bank below is organized by tier. Tier 1 targets the simplest syllable shapes (CV, VC). Tier 2 targets CVCV and reduplicated forms. Tier 3 targets multisyllabic words. Tier 4 targets phrase and sentence level production with appropriate prosody. Most children with CAS begin at Tier 1 or 2 regardless of age, because motor speech therapy respects where the motor system currently is, not where the child "should" be developmentally.

What do well-written CAS therapy goals actually look like?

A well-written goal has four parts: the condition (what stimulus, what cuing level), the target behavior, the accuracy criterion, and the measurement timeframe. Vague goals like "will improve speech intelligibility" are not measurable and will not drive good treatment decisions.

Here is a 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 carries most of the weight in a CAS goal. Children with CAS typically need heavy cuing early in treatment, and the goal should specify whether you are working with maximum cuing (simultaneous modeling, tactile cues, slow rate), moderate cuing (immediate imitation), or minimal cuing (delayed imitation or spontaneous). Over a treatment arc, you write a series of goals that progressively reduce the cuing level. That reduction is how you prove motor learning is actually happening.

Accuracy thresholds for CAS goals are often set lower initially than you would see in articulation goals, sometimes 70 to 80% at the most supported cuing level, then 80 to 90% at an independent level before moving to a harder syllable shape tier. Requiring 90% accuracy with maximum cuing before moving forward can actually stall progress by keeping a child in a drill pattern too long. Motor learning research (Schmidt & Lee, Motor Control and Learning, 6th ed.) suggests that some variability is healthy during acquisition; you want to see a consistent upward trend, not perfection ^[12].

For speech therapy with a licensed SLP, having these goal components written out before the IEP meeting means you are not accepting a boilerplate goal that will be hard to track.

Goal bank tier 1: CV, VC, and CVC syllable shapes

These are the building blocks. A child who cannot yet produce consistent CV syllables reliably needs to work here before moving to multisyllabic words, regardless of age.

Sample Tier 1 goals:

1. Given simultaneous modeling (maximum cuing), [name] will produce CV targets (e.g., "go," "no," "me," "bye") with 80% accuracy across 3 consecutive sessions of at least 20 trials each, as measured by SLP probe data.

2. Given immediate imitation (moderate cuing), [name] will produce CV targets from a 10-word functional vocabulary set with 80% accuracy across 3 consecutive sessions, as measured by recorded probes.

3. Given a delayed imitation condition (minimal cuing), [name] will produce VC targets (e.g., "up," "on," "eat") with 80% accuracy across 3 consecutive sessions of 20 trials, as measured by SLP probe data.

4. Given immediate imitation, [name] will produce CVC words containing early-developing consonants (nasals, stops, glides) with accurate vowel production in 75% of trials across 3 consecutive sessions.

5. Given maximum cuing with visual and tactile support, [name] will demonstrate reduced vowel distortion on CV and CVC targets, achieving correct vowel identity in at least 70% of trials across 4 sessions.

A note on vowels: many articulation goal banks never mention vowels. CAS goals should. Vowel errors are a hallmark feature of CAS ^[1], and ignoring them means ignoring a diagnostic and therapeutic priority.

Goal bank tier 2: CVCV, reduplications, and two-syllable words

Once a child is hitting Tier 1 targets at the minimal cuing level, it is time to move to two-syllable shapes. Reduplicated forms ("mama," "dada," "bye-bye") are often the bridge because the motor plan is repeated, not novel, for each syllable.

Sample Tier 2 goals:

1. Given immediate imitation, [name] will produce reduplicated CVCV words (e.g., "mama," "bye-bye," "no-no") with 80% accuracy across 3 consecutive sessions of 20 trials each.

2. Given immediate imitation, [name] will produce varied CVCV words (e.g., "baby," "cookie," "doggy") with 75% accuracy across 3 consecutive sessions, as measured by SLP probe data.

3. Given minimal cuing (spontaneous or self-initiated context), [name] will produce a 5-word functional CVCV vocabulary with 80% accuracy across 3 consecutive sessions in at least two different settings.

4. Given immediate imitation with visual cuing, [name] will produce two-syllable words with appropriate lexical stress (correct syllable stressed) in 70% of trials across 4 consecutive sessions.

5. Given a structured play routine with moderate cuing, [name] will produce two-syllable functional words to request or comment with 75% accuracy across 3 sessions, as measured by clinician probe.

The stress goal in item 4 often gets dropped from CAS goal banks because it is harder to measure. Inappropriate stress is a core diagnostic marker ^[1]. Skip it, and you may end up with a child who says words correctly in isolation but sounds robotic or hard to follow in conversation.

Goal bank tier 3: multisyllabic words and word shapes with clusters

Moving to three and four syllable words is a big motor planning jump. Some children with more severe CAS spend a long time at Tier 2 before moving here. That is fine. Trying to rush to multisyllabic targets before lower tiers are solid usually produces compensatory strategies and inconsistent errors that are hard to unpick later.

Sample Tier 3 goals:

1. Given immediate imitation, [name] will produce three-syllable words (e.g., "banana," "computer," "umbrella") with 75% accuracy across 3 consecutive sessions of 20 trials.

2. Given minimal cuing, [name] will produce three-syllable words from a 10-word target set with 80% accuracy across 3 consecutive sessions, as measured by recorded probes.

3. Given immediate imitation, [name] will produce words containing consonant clusters (e.g., "stop," "play," "friend") with 70% accuracy across 3 consecutive sessions.

4. Given a delayed imitation condition, [name] will produce multisyllabic words with appropriate syllable segregation (no added schwa between consonants) in 75% of trials across 4 sessions.

5. Given minimal cuing in structured conversation, [name] will produce a 10-word set of three-syllable functional vocabulary items (chosen collaboratively with family) with 80% accuracy across 3 sessions in two different contexts.

For preschool children, the vocabulary for Tier 3 should come from words they actually need to communicate at home and at school. An SLP who lets the family contribute the target word list will get much better carryover because the child hears those words in natural contexts every day. This matters most when you are writing goals for apraxia of speech preschool IEP targets.

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

Phrase and sentence goals are where CAS therapy connects to real communication. A child who produces words accurately in isolation but cannot chain them into functional phrases still has a serious communication barrier. Prosody, the rhythm and melody of speech, becomes the main target at this tier.

Sample Tier 4 goals:

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.

The unfamiliar listener criterion in goal 5 earns its place because CAS affects intelligibility to people who do not know the child well. A parent can often understand their child perfectly while a teacher or peer cannot. Measuring intelligibility to unfamiliar listeners 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 CAS goals do three things at once: they stay measurable, they connect to classroom participation, and they reflect the motor speech nature of the disorder instead of just counting correct sounds. For a 3 to 5 year old, the most functional targets are words and phrases that help the child join the preschool day: calling a friend's name, requesting help, labeling objects during circle time, commenting during play.

The motor complexity of those targets varies, so you pull the appropriate syllable shape tier for where the child currently sits.

Here are three sample preschool-specific 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.

Early intervention matters a great deal for CAS. The brain's motor learning capacity is greatest in early childhood, and the research on early intervention consistently shows better long-term outcomes when treatment begins before age 5 ^[3]. Under IDEA Part C (for children birth to 3) and Part B (ages 3 to 21), children with a diagnosed motor speech disorder are eligible 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 motor learning principles should guide treatment, specifically calling out high practice intensity, knowledge of results, and distributed versus blocked practice schedules ^[1]. IEP goals that do not reflect these principles are really articulation goals wearing a CAS label, which is a mismatch.

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

More than most SLPs typically run. That is the short answer from motor learning research, and it surprises a lot of families.

Dynamic Temporal and Tactile Cueing (DTTC), one of the most widely researched CAS treatments, uses high-intensity practice with 100 or more productions of targets per session in some protocols ^[5]. The Nuffield Dyspraxia Programme and ReST (Rapid Syllable Transition Treatment) also treat high repetition as a core component. 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].

For a child receiving one 30-minute session per week in a school setting, that intensity is impossible to replicate in therapy alone. This is why home practice is not optional for CAS. Goals should ideally include a home practice component, or at minimum the IEP should note that a home program will be provided.

Apps and tech tools that provide structured, repetitive practice with feedback can bridge the gap between weekly sessions. Little Words was built with this gap in mind, offering motor-speech-informed practice routines that parents can run at home between sessions. It is not a replacement for a skilled SLP, but it can meaningfully increase the number of repetitions a child gets each week.

You can write intensity straight into the goal: "across 3 consecutive sessions of at least 50 trials each" is a legitimate way to make sure whoever provides the therapy is delivering real dosage.

How do you track progress on CAS goals?

Two measurement tools carry most of the load: probe data and language samples. For CAS, probe data is usually the primary measure. You present the target words in a standardized way (imitation or spontaneous), record the response, and score it.

Scoring options include:

• Percent correct (whole-word accuracy, where the word is correct only if all phonemes and stress are right)
• Percent consonants correct (PCC)
• Percent vowels correct (PVC, which is often low in CAS and worth tracking separately)
• Correct stress pattern (yes/no per word)

For very young children or children with severe CAS, whole-word accuracy can be discouraging because it demands that every part of the word be right. A child might score 0 words even while making real progress on individual features. In those cases, tracking multiple dimensions (vowels separately, stress separately) gives a fuller picture.

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

A practical approach: take a 20-item probe at the start of every 5 to 6 sessions, record the session, and score using the criteria in the goal. Graphing the data over time is both a clinical best practice and something you can share with families and review at IEP meetings.

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

CAS and autism often co-occur. A 2015 study estimated that 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 can also occur in children with no autism diagnosis, with no other developmental differences at all.

When CAS co-occurs with autism, the motor speech goals do not fundamentally change, because the motor planning deficit in CAS is the same regardless of what other diagnoses a child carries. You still work through the syllable shape hierarchy, you still apply motor learning principles, and you still systematically fade cuing. What changes is how you structure the therapy environment, the reinforcement system, and the social context of practice to fit the child's profile.

For minimally verbal children with autism who also have CAS, a real question is whether to target verbal speech, AAC devices, or both at once. Current speech-language research holds that AAC does not suppress verbal speech development and may support it by reducing communicative frustration ^[8]. Goals for a child with both CAS and autism can therefore run in parallel: motor speech goals for verbal production alongside AAC goals for independent functional communication.

For more on this intersection, the autism spectrum speech therapy page has a broader breakdown of communication goal frameworks for autistic children.

If you are working with a primarily autistic child whose speech involves a lot of 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.

What evidence-based CAS treatments should the goals align with?

Four treatments carry the strongest published evidence base for CAS as of the mid-2020s. Your goals should match whichever approach the SLP is using, because the same goal can be targeted very differently depending on the method.

DTTC (Dynamic Temporal and Tactile Cueing): Developed by Strand and colleagues ^[9]. Uses a cueing hierarchy from simultaneous production through direct imitation to spontaneous production. Goals written for DTTC should name the cuing level explicitly.

ReST (Rapid Syllable Transition Treatment): Developed by Murray, McCabe, and Ballard ^[6]. Targets accurate production and smooth transitions between syllables using nonwords to ensure novelty. Goals for ReST often target nonword probes, which is unusual but has good evidence behind it.

NDP3 (Nuffield Dyspraxia Programme, 3rd ed.): A structured motor speech program widely used in the UK. Targets build from sounds to words to phrases in a systematic hierarchy.

Integrated Phonological Awareness (IPA): Addresses both motor speech and phonological awareness, which is often co-impaired in CAS because these children get limited practice with sound patterns. Goals here include both motor speech targets and phonological awareness tasks.

ASHA's Practice Portal summarizes the evidence for each approach and is the most current freely available clinical resource ^[1]. The portal also separates CAS from other motor speech disorders, worth reviewing if you are unsure whether a child's profile fits CAS specifically.

For childhood apraxia of speech specifically, the Apraxia Kids treatment guidelines are the most detailed family-facing resource and line up with ASHA's clinical recommendations ^[2].

How often should CAS goals be updated?

For most children with CAS in a school setting, IEP goals are written annually, but progress should be reviewed far more often. IDEA requires progress reports at least as often as report cards are issued ^[4]. For CAS specifically, many SLPs recommend reviewing probe data every 6 to 10 sessions to decide whether to hold at a target or move to the next tier.

A child who is hitting 80% accuracy at minimal cuing on a tier consistently across three sessions is ready to move up. A child stuck below 60% for six sessions may need a different cuing approach, a different target set, or a fresh look at whether CAS is the right framework at all.

Goal banks are most useful as a menu, not a prescription. You pick the tier and the cuing level that match the child today, set a criterion for advancement, and plan ahead for the next goal when the current one is met. Writing "when this goal is mastered, the team will move to [next goal]" directly into the IEP is a legitimate practice and saves time at annual reviews.

For families doing home practice between sessions, short daily practice of five to ten minutes beats one long weekly session for motor learning. That is a direct application of the distributed practice principle. Tracking how often home practice actually happens is worth building into the monitoring plan, because a child who gets one 30-minute school session per week and no home practice is receiving a fraction of the dosage the research was built on.

Where can families and SLPs find free CAS goal bank resources?

A few genuinely useful free resources exist, and it helps to know what each one actually contains.

Apraxia Kids: The most detailed nonprofit resource for CAS in the US. Their website includes treatment summaries, school tool kits, and a directory of SLPs with CAS training. They do not publish a formal goal bank, but their treatment guidelines are the closest thing ^[2].

ASHA Practice Portal, CAS page: Free to anyone, more than ASHA members. Contains the diagnostic criteria, evidence summaries for each treatment approach, and clinical decision-making frameworks ^[1].

DTTC resources from Edythe Strand's published work: Several published articles and some freely available clinical materials describe how to implement DTTC and structure targets. Searching "Strand DTTC protocol" in Google Scholar or PubMed will surface these ^[9].

State early intervention program goal banks: Several state education agencies publish free IEP goal banks for speech-language services. Quality varies enormously for CAS specifically. California's Department of Education and Minnesota's Department of Education both have speech goal banks publicly available, though you will need to adapt generic speech goals to the motor learning framework.

For families entering the school system for the first time, the early intervention article explains the federal eligibility framework and what to expect from the evaluation process. If you are thinking about supplementing in-person therapy, the online speech therapy article covers what telehealth SLP services look like and how to find providers with CAS expertise.

If your child is school-age and you want a broader picture of the therapy process beyond goals, the speech therapy speech therapist article covers session structure, frequency recommendations, and how to judge whether an SLP is a good fit.

Frequently asked questions

What is a goal bank for apraxia of speech?

A CAS goal bank is a library of pre-written, measurable speech therapy goals organized by syllable shape complexity and cuing level. Because CAS is a motor speech disorder, the goal bank needs to reflect motor learning principles: high repetition, systematic cuing hierarchies, and progress criteria that capture both accuracy and prosody. Generic articulation goal banks do not work well for CAS because they miss vowel errors, stress errors, and the cuing dimension.

What are the core features of CAS that goals should target?

ASHA identifies three core features of CAS: inconsistent errors on consonants and vowels, lengthened and disrupted transitions between sounds and syllables, and inappropriate prosody (stress, rhythm, and intonation). Well-written CAS goals should address all three, not consonant accuracy alone. Many SLPs borrow articulation goals that only track consonant production and miss vowel errors and prosody entirely.

How do you write a measurable CAS goal for an IEP?

Use this 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 sets CAS goals apart from articulation goals. Make it specific: simultaneous modeling, immediate imitation, delayed imitation, or spontaneous production.

What are good goals for apraxia of speech for preschool children?

Preschool CAS goals should target functional vocabulary the child needs for classroom participation: requesting help, labeling objects, greeting peers. The syllable shape tier should match the child's current motor level, not their age. A 4-year-old at Tier 1 needs CV and CVC goals, not three-syllable word goals. 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.

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

Research-based CAS treatments like DTTC and ReST use 50 to 100+ productions per session. This is far higher than what most 30-minute school therapy sessions deliver. Home practice is not optional for CAS: distributed daily practice of 5 to 10 minutes produces better motor learning outcomes than one longer weekly session alone. Goals can specify minimum trial counts per session (e.g., "across sessions of at least 50 trials") to build dosage into the plan.

What is the difference between CAS goals and articulation goals?

Articulation goals target sound-level accuracy (e.g., "produce /s/ correctly in 80% of words"). CAS goals target motor planning at the syllable and word level, specify cuing conditions, address vowels and prosody, and systematically fade cuing over time. Applying an articulation goal framework to CAS often means missing the disorder's core features and slowing progress.

Should CAS goals include vowels?

Yes. Vowel errors are a hallmark diagnostic feature of CAS according to ASHA's technical report. Many SLPs trained primarily in articulation disorders rarely write vowel goals because vowel errors are uncommon in typical articulation disorders. For CAS, tracking percent vowels correct (PVC) separately from consonants gives a much more accurate picture of motor speech progress, especially at Tier 1 and Tier 2.

What happens if a child is stuck on a CAS goal for months without progress?

Lack of progress after 6 to 10 sessions at the same target usually means one of a few things: the cuing level is too challenging, the targets are not the right syllable shape tier, the session dosage is too low, or the diagnosis needs re-examination. CAS is sometimes misdiagnosed; a child who is not responding to motor speech treatment may have a different profile. A second opinion from an SLP with CAS specialty training is reasonable to request.

Can a child with CAS also use AAC while working on verbal speech goals?

Yes, and current evidence supports using both at once. AAC does not suppress verbal speech development and can reduce communicative frustration while motor speech skills build. For minimally verbal children with CAS, running parallel AAC goals and motor speech goals is standard practice. ASHA and Apraxia Kids both support this approach. The choice of which AAC system to use should be guided by the child's current motor and cognitive profile.

How does CAS affect intelligibility, and should intelligibility be a goal?

CAS significantly reduces speech intelligibility, especially to unfamiliar listeners, because motor errors are inconsistent and affect both segments and prosody. Intelligibility to unfamiliar listeners is a legitimate functional goal at the phrase and sentence level. You can measure it by having an unfamiliar person transcribe or rate a speech sample. A criterion like "rated as mostly intelligible by an unfamiliar listener in 60% of sampled utterances" is measurable and functional.

What is DTTC and should CAS goals reference it?

Dynamic Temporal and Tactile Cueing (DTTC) is a CAS treatment approach developed by Edythe Strand. It uses a structured cuing hierarchy from simultaneous production through spontaneous production. Goals written for DTTC explicitly name the cuing level at which accuracy is measured. It is one of the approaches with the strongest published evidence base for CAS according to ASHA's Practice Portal.

Is CAS covered by insurance or school services?

In the US, children ages 3 to 21 with a CAS diagnosis qualify for speech-language services through the public school system under IDEA Part B at no cost to families. Children birth to 3 may qualify under IDEA Part C. Private insurance coverage for outpatient speech therapy varies by plan and state. Many states have autism insurance mandates that cover speech therapy if autism is also diagnosed, but CAS alone does not trigger those mandates.

How do you know when to move from one goal tier to the next?

The standard benchmark is 80% accuracy at the minimal cuing level (delayed imitation or spontaneous production) across 3 consecutive sessions. Moving up too early means the motor plan is not yet stable. Staying too long at a mastered tier wastes therapy time. Some SLPs write the advancement criterion directly into the IEP goal so the team does not have to make a new decision at each session.

Are there free tools to track CAS goal progress?

Apraxia Kids provides free probe word lists and some recording forms on their website. ASHA's Practice Portal has free clinical guidance. Many SLPs create their own probe forms in a spreadsheet. The key is to probe consistently using the same word set and scoring criteria across sessions, record the session if possible, and graph the data so trends are visible at IEP meetings.
