School Evaluation vs. Private Autism Diagnosis in Fort Bend ISD: What's the Difference?

Quick answer: A Fort Bend ISD school evaluation determines whether your child qualifies for special education services at school. A private autism diagnosis from a licensed psychologist is a medical diagnosis that directs treatment and is required for insurance-covered ABA therapy. They are not interchangeable — most families end up needing both.

What a school evaluation does

A Fort Bend ISD evaluation establishes educational eligibility — the supports and accommodations your child receives in the classroom. Even when a psychologist is involved, the purpose is educational, not medical. Fort Bend ISD also runs an Early Intervention Academy at Quail Valley Elementary in Sugar Land.

What a private diagnosis does

A private evaluation answers a different question: does your child have autism, medically? This is the diagnosis that directs treatment planning and that insurance and Medicaid require before authorizing ABA, speech, or occupational therapy.

Why you may need both

The school evaluation supports your child at school. The private diagnosis unlocks therapy outside of school. One does not replace the other.

After the private diagnosis

Once you have a medical diagnosis, ABA can begin. All Aboard ABA in Sugar Land offers fast-start intake so your child doesn't lose months waiting.
