Full Goal

Given a verbal model, visual placement cue (mirror or diagram), and a straw or tongue-blade tactile prompt, [Student] will produce /s/ with a midline airstream in CV, VC, and CVC syllables with 70% accuracy across 3 consecutive data collection sessions, as measured by SLP perceptual judgment of airstream direction during structured probes.

Individualization Guidance

Before using this goal, verify:

• Lateralization is established, not transient. Lateralized /s/ is often resistant to maturation by age 7–8. If the student is younger and the error is inconsistent, monitoring may be more appropriate than direct intervention.
• Choose tip-up or tip-down based on what the student can produce. Both placements are clinically acceptable. Don’t switch midway through a treatment block — pick one and stay with it through generalization.
• Tactile prompts matter. A straw between the teeth gives clear feedback for midline airflow; a tongue blade scaffolds tip placement. Specify which prompt is being used in your data.
• Auditory discrimination first. Confirm the student can perceptually distinguish a lateralized /s/ from a midline /s/ before targeting production. If not, build discrimination as a prerequisite.
• Co-occurring patterns. Lateralized /z/, /ʃ/, /tʃ/, and /dʒ/ often co-occur. Decide whether you are working /s/ in isolation or whether the broader sibilant pattern needs targeting.

Clinical Notes

Lateralized /s/ is a placement error, not a developmental delay — the student is producing a stable but atypical motor pattern. Treatment is about shifting the airstream and tongue posture, not waiting for the sound to emerge. The 70% criterion at moderate support reflects that motor reorganization is gradual; expect plateaus and brief regressions when fading cues.

The “midline airstream” descriptor in the criterion is the clinically meaningful target, not just “correct /s/.” Two student productions can both sound roughly correct but only one routes air down the center — and the lateral pattern reasserts under fatigue or fast speech. Note airstream direction in your data, not just accuracy.

Do not collapse this goal with general “produce /s/ with 80% accuracy” — that phrasing hides the lateralization and makes generalization data ambiguous.
