The IEE process is designed to be clear, supportive, and predictable. Each step ensures that families and school teams receive accurate, student-centered information they can trust.
1. Intake & Record Review
We begin by listening to your concerns and reviewing existing assessments, IEP documents, and school data to understand your child’s needs.
2. Evaluation Sessions
Your child participates in standardized testing, observations, and interviews across the requested disciplines — conducted with care and clarity.
3. IEP-Ready Final Report
A clear, detailed report is provided — with recommendations that help IEP teams make informed decisions. Most evaluations are completed within 30 days.
