COTA School-Based Practice: Handwriting, Sensory Supports, and IEP Data
Ms. K is an 8-year-old second grader with autism spectrum disorder who receives school-based OT under an IEP. The OTR completed the initial evaluation; a COTA provides weekly 30-minute individual sessions and monthly classroom consultation. The teacher reports that Ms. K refuses handwriting tasks, covers her ears during assemblies, and chews her shirt sleeve. A recent writing sample shows poor spacing, inconsistent letter size, and reversals of b and d. During a classroom observation, Ms. K completed two sentences when given a weighted lap pad and noise-reducing headphones, but dropped her pencil after 6 minutes. The IEP goal is 'will write a three-sentence paragraph with legible handwriting in 4 of 5 trials.' The teacher asks the COTA to 'just practice handwriting every session' because writing is the IEP goal. The COTA has 12 weeks before annual review.
1. How should the COTA decide whether to address handwriting directly, sensory regulation, or both?
Read the worked answer
The COTA should use the observation data rather than assume that handwriting refusal is purely sensory or purely motor. The trial with the weighted lap pad and headphones increased output to two sentences but fatigue appeared after 6 minutes, so sensory supports may improve access without solving endurance or handwriting mechanics. The COTA should analyze the task: letter formation, spacing, pencil control, seating, paper position, and fatigue. Then trial short handwriting tasks with and without the sensory supports, measuring legibility, time, cues, and breaks. If supports improve performance, use them as an access strategy while continuing handwriting instruction. If refusal persists or the child shows distress, the COTA should not force practice; instead, consult the OTR about modifying the plan and considering a sensory or behavioral support plan. The IEP goal remains the outcome, but the service delivery method must match the child's needs. The COTA should avoid a single-cause explanation and document the trials that guide the decision.
2. What data should the COTA collect, and how should progress be documented and shared?
Read the worked answer
Document baseline and repeated measures: amount written, legibility, spacing, letter reversals, time on task, prompts, breaks, sensory supports used, and signs of fatigue or distress. Use a simple data sheet that the teacher can also complete during classroom writing so the COTA can see carryover. Compare conditions, such as with and without headphones or lap pad, and note whether gains maintain across settings. Report objective changes rather than labels like 'improved attention.' Share data with the OTR and teacher at monthly consultation and before the annual review. If the child writes two sentences with supports but not three, the team can adjust the goal criteria or the intervention. The COTA should also document consultation time, teacher training, and environmental modifications. This documentation supports IEP decisions and shows whether the service is effective. If data show no progress after a reasonable trial, the COTA should request OTR review rather than continue the same sessions.
3. When should the COTA contact the OTR about this case?
Read the worked answer
The COTA should contact the OTR when the data show lack of progress, a change in the child's response, or a need to alter the evaluation or IEP goal. Specific triggers include increased distress during handwriting, new sensory or behavioral concerns, a medical change, or a trial of supports that is not working after a reasonable period. The COTA should also consult before recommending new equipment, changing the service frequency, or writing IEP progress notes that interpret evaluation results. In this case, because the teacher is asking for handwriting-only sessions and the child shows fatigue after 6 minutes, the COTA should bring the trial data to the OTR to decide whether the plan should include sensory regulation, handwriting instruction, or both. The OTR remains responsible for evaluation, goal development, and supervision according to state law and school policy. The COTA implements and reports; the OTR interprets and adjusts the plan.
