Autism Reevaluation With Discrepant Raters
Ana, age 6, is a first grader eligible under developmental delay. Her triennial reevaluation is due. Her teacher reports that Ana follows routines, has friends, and meets grade-level benchmarks; she describes Ana as “a little quirky.” Her mother reports that Ana lost phrases she used at age 3, lines up toys for 30 minutes, covers her ears at fire drills, and has meltdowns at transitions. A prior ADOS-2 at age 3 was inconclusive; a new teacher rating scale is in the average range, while the parent’s rating is elevated. Ana’s hearing is normal. She speaks English at school and Spanish at home. The team has 60 days. The parent requests an independent educational evaluation at district expense before the meeting. The district says the existing data are sufficient.
1. Must the district conduct additional assessment, and how should the IEE request be handled?
Read the worked answer
The district should not rely on the existing data as sufficient. The question is not whether Ana is “quirky” but whether she meets the criteria for autism or another disability and what services she needs.
- Additional assessment is warranted. The teacher and parent data conflict, the prior ADOS was inconclusive, and there is a reported history of lost language. A comprehensive reevaluation should include developmental history, autism-specific observation and rating scales, communication assessment, and information across home and school.
- The IEE request triggers a legal obligation. Under IDEA, when a parent requests an IEE at public expense because they disagree with the district’s evaluation, the district must either agree to provide it or request a due process hearing to defend its evaluation. It cannot simply refuse because it believes its data are sufficient.
- Do not delay the reevaluation while resolving the IEE. The 60-day timeline continues unless extended by mutual agreement or due process.
- Explain the process to the parent in plain language, including that the district may provide the IEE or defend its evaluation.
The district’s position that existing data are sufficient is weakened by the discrepant raters and the inconclusive prior assessment.
2. How would you reconcile the discrepant parent and teacher ratings and avoid cultural and linguistic bias?
Read the worked answer
Discrepant ratings are data, not a problem to erase. They may reflect real differences in settings, expectations, or the child’s behavior with different adults.
I would:
- Compare the contexts. Ask the teacher about fire drills, transitions, peer play, and repetitive behavior specifically, rather than relying on a global impression.
- Use direct observation in multiple settings, including less structured times such as lunch and recess, because autism-related behavior may be less evident during structured academic tasks.
- Obtain a developmental history from the parent, including early language milestones, regression, play patterns, and sensory responses.
- Consider language and culture. Ana is bilingual, and some behaviors may reflect language brokering, cultural expectations, or second-language acquisition. The assessment should include Spanish-language information and an interpreter if needed.
- Avoid over-relying on one instrument. A single rating scale, especially one completed by only one teacher, is not enough.
- Document the discrepancy and explain how it was resolved in the evaluation report.
The goal is not to force the raters to agree but to determine whether the pattern of behavior is consistent with autism across settings and history.
3. What eligibility framework would you use at the meeting, without prejudging the outcome?
Read the worked answer
I would frame the discussion around the IDEA criteria and the evidence needed, not around a predetermined label.
- Autism: Does Ana show qualitative deficits in social communication and restricted or repetitive patterns of behavior, and are these educationally relevant? Evidence should include developmental history, observation, parent/teacher information, and communication data.
- Developmental delay: Is she still eligible under the state’s developmental-delay criteria, and does she need special education services?
- Other health impairment or speech-language impairment: Consider whether another category better explains the profile.
- Adverse educational effect: Even if criteria are met, the team must determine whether the disability affects educational performance and requires specially designed instruction.
The team should review the new evaluation, the parent’s concerns, the teacher’s observations, and the language data. The recommendation should follow the evidence, and the report should explain why the team accepted or rejected each category.
