Overview
Autism therapy and services in Farmers Branch
With more than 30 years in Texas schools, Diagnostic Assessment Services (DAS) is a Farmers Branch-based special education contractor whose staff includes educational diagnosticians, school psychologists, SLPs, OTs, PTs, and licensed counselors. Schools bring them in for the full spectrum of SPED work — autism team evaluations, psycho-educational testing, speech and OT services, dyslexia therapy, and ARD support. Services are delivered on-campus or virtually, depending on the district's needs.
Best for
Families whose child is going through the school-based special education process and needs a thorough autism or psycho-educational evaluation completed through the district.
Their approach
DAS embeds with school districts as a compliance and quality partner rather than running a standalone clinic — their evaluators attend ARD meetings, present findings, and develop IEP goals alongside campus teams. Autism evaluations use a team-based model drawing on psychological, behavioral, and functional assessment components.
What to expect
Because DAS contracts directly with school districts, parents typically access their services through the campus SPED coordinator rather than scheduling directly; evaluations are conducted in-school or via telehealth, with a formal ARD presentation of results.
