Consonant cluster IEP goals: 16 examples with a scoring plan
By the IEP Atlas editorial teamLast updated
Short answer
A consonant cluster goal names the cluster type, the position, the level and a criterion based on words where both sounds are present. Example: given 20 untrained words starting with s-clusters such as stop and snail, Ivy will say both consonants in 16 of 20 words across 2 consecutive probes. Score cluster reduction and sound errors separately.
A consonant cluster is two or three consonants side by side with no vowel between them: the "st" in stop, the "pl" in play, the "nd" in hand. Children who reduce clusters say only one of the sounds, so "stop" becomes "top" and "play" becomes "pay." The 16 goals below cover each cluster type, with a probe schedule and a filled-in data sheet at the end. The numbers are illustrations.
Sound-by-sound goals are on the articulation goals examples pillar. Cluster reduction as one of several patterns is covered in phonological processes IEP goals.
Before you write a cluster goal
Clusters build on single sounds. A child who cannot say /l/ alone will not say a clean "bl," so check the singletons first. The ages when most children produce single consonants are a useful guide: /s/ and /l/ are usually in place by about age 5 and /r/ by about age 6.[1] Clusters come later than the singletons inside them.
Separate two kinds of error, because they need different goals:
- Cluster reduction. One sound is missing: "top" for stop. This is a pattern, and a cluster goal fits.
- A sound error inside the cluster. Both slots are filled, but one sound is wrong: "bwue" for blue. The cluster is there; the /l/ is not. Write an /l/ goal, or a goal that targets /l/ in clusters.
ASHA treats these as different kinds of speech sound errors, with pattern errors handled as phonology and single-sound errors as articulation.[2]
Which cluster goal to choose
| What you see now | Sub-skill to target | Measurement method |
|---|---|---|
| "top" for stop, "nake" for snake | Initial s-clusters | Percent of 20 untrained words |
| "pay" for play, "bed" for bread | l- and r-clusters | Percent of 20 words per cluster type |
| "han" for hand, "tes" for test | Final clusters | Percent of 20 words ending in clusters |
| Two-sound clusters correct, "seet" for street | Three-sound clusters | Percent of 15 words |
| Clusters correct in words, reduced in talk | Sentences, reading and conversation | Percent of target words in a sample |
Initial s-cluster goals
s-clusters are often the first cluster target, because many children have a good /s/ by kindergarten.
- Given 20 untrained words starting with "st," "sp," "sn" or "sm," Ivy will say both consonants in 16 of 20 words across 2 consecutive probes. Baseline: 3 of 20. Template.
- When the SLP says "s" and "nail" apart, Ivy will blend them into the cluster word in 8 of 10 trials across 2 sessions. Baseline: 2 of 10. Template.
- Using the carrier phrase "I can ___," Ivy will say s-cluster action words (swim, skip, spin) with both sounds in 17 of 20 phrases. Baseline: 6 of 20. Template.
- Given 20 untrained words with s-clusters in a 2-week cycle, Diego will say both consonants in 14 of 20 words at the end of the cycle. Baseline: 4 of 20. Template.
Weak: "Ivy will produce s-blends with 80% accuracy." Measurable: The first goal in this section. It lists the clusters, the number of words and that they are untrained.
l-cluster and r-cluster goals
Target l-clusters and r-clusters only when the singleton is correct in words. Otherwise the goal measures /l/ or /r/, not the cluster.
- Given 20 words with "bl," "pl," "fl," "cl" or "gl," Diego will say both consonants with a correct /l/ in 16 of 20 words across 3 sessions. Baseline: 5 of 20. Template.
- Given 20 words starting with "cl," "gl," "cr" or "gr," Owen will keep the back sound and the second consonant in 16 of 20 words. Baseline: 7 of 20. Template.
- Given 2 pictures with r-cluster words (such as tree and frog), Owen will make up a sentence and say both clusters correctly in 8 of 10 sentences. Baseline: 2 of 10. Template.
- Given 20 picture words with clusters in the initial position, Owen will say the full cluster after a model in 18 of 20 words across 2 sessions. Baseline: 9 of 20. Template.
Weak: "Diego will say l-blends." Measurable: The first goal in this section. It names the blends and says the /l/ must be correct, which separates the cluster from the sound.
Final cluster goals
Final clusters carry grammar: plural -s after a consonant (cats), past tense (jumped), and many common words (hand, milk, desk).
- Given 20 words ending in "-st," "-ts" or "-ks," Ivy will say both sounds of the final cluster in 16 of 20 words across 3 sessions. Baseline: 6 of 20. Template.
- Given 20 words ending in "-nd," "-nt" or "-lk," Diego will say both final consonants in 15 of 20 words. Baseline: 5 of 20. Template.
- When describing 10 pictures of plural objects (such as cats and ducks), Diego will say the final cluster with the plural in 8 of 10 sentences. Baseline: 3 of 10. Template.
Weak: "Ivy will use final blends." Measurable: The first goal in this section, with the cluster endings and a denominator.
Three-consonant cluster goals
- Given 15 words with "str," "spl," "spr" or "scr," Owen will say all three consonants in 12 of 15 words across 3 sessions. Baseline: 2 of 15. Template.
- Given 10 sentences with a two-sound and a three-sound cluster word (such as "The spider is on the street"), Owen will say both clusters correctly in 7 of 10 sentences. Baseline: 1 of 10. Template.
Weak: "Owen will produce complex clusters." Measurable: The first goal in this section. "Complex" becomes a list of four clusters.
Sentence, reading and conversation goals
- While reading a short passage with 10 marked cluster words, Ivy will say the full cluster in 8 of 10 words on 3 consecutive passages. Baseline: 4 of 10. Template.
- During a 3-minute conversation, Diego will say clusters with all sounds in 75% of cluster words on 2 of 3 monthly samples. Baseline: 30%. Template.
- During structured conversation, Owen will catch and fix a reduced cluster in 3 of 5 errors across 3 sessions. Baseline: 0 of 5. Template.
Weak: "Diego will carry over clusters into conversation." Measurable: The second goal in this section. It names the sample length and counts only cluster words.
How to measure cluster goals
Probe with untrained words every 2 weeks at the start of the session, before any practice. Use 20 words for a two-sound cluster goal and 15 for three-sound clusters. Score each word with one of four codes:
- C: correct, every sound in the cluster present and accurate.
- R: reduced, one sound missing ("top" for stop).
- S: both slots filled, but one sound substituted ("bwue" for blue).
- E: epenthesis, an extra vowel between the sounds ("suh-top").
Only C counts toward the goal. R, S and E tell you what to teach next: a child moving from R to E is getting closer, because both consonants are now there. The opportunity trial data sheet has room for 20 coded trials, and the opportunities measurement guide explains how to handle prompted responses.
A filled-in data sheet for an s-cluster goal
This is Ivy's sheet for the first s-cluster goal (16 of 20 untrained words). Each row is one cold probe.
| Date | C | R | S | E | Score |
|---|---|---|---|---|---|
| Sep 9 (baseline) | 3 | 16 | 0 | 1 | 3 of 20 |
| Sep 23 | 5 | 12 | 0 | 3 | 5 of 20 |
| Oct 7 | 8 | 8 | 1 | 3 | 8 of 20 |
| Oct 21 | 11 | 5 | 1 | 3 | 11 of 20 |
| Nov 4 | 13 | 4 | 1 | 2 | 13 of 20 |
The rise in E in September is a good sign: Ivy now knows a second sound belongs there. By November she is at 13 of 20, on track for 16 of 20 by spring. Graph the C column so the trend is visible at the progress report. For the full session routine, see speech therapy data collection.
Adapting by grade
| Grade band | Typical focus | Example change |
|---|---|---|
| Pre-K | s-clusters in play, blending two sounds | 10 to 15 words per probe, picture games |
| K to 1 | s- and l-clusters, plurals | Tie probes to phonics words with blends |
| Grades 2 to 3 | r-clusters, three-sound clusters | Reading passages with marked words |
| Grade 4 and up | Clusters in long content words | Science and social studies vocabulary |
Teachers working on blends in phonics can use the same word lists; the consonant blends activities guide shows how. All templates are on the articulation goals page, and the goal checker will flag a missing denominator.
Frequently asked questions
Is "bwue" for blue cluster reduction?
No. Both consonant slots are filled, so the cluster is intact. The /l/ is replaced by /w/, which is gliding. Write an /l/ goal or score it as a substitution inside the cluster, not as reduction.
Which clusters should I target first?
Start with clusters whose single sounds the child already says correctly, often s-clusters. Leave r-clusters until /r/ is correct in words. Final clusters such as -ts and -ks can run alongside initial clusters if plurals are a concern.
How often should I probe cluster goals?
Every 2 weeks is enough for most students. Use 20 untrained words for two-sound clusters and 15 for three-sound clusters, at the start of the session before practice.
