About Ascent School

Founded in 1998, Ascent School for Individuals with Autism in Deer Park, NY, is a New York State Education Department (NYSED) approved Chapter 853 nonpublic special education school. Ascent is dedicated exclusively to providing intensive, evidence-based educational and behavioral intervention for individuals ages 3 through 21 diagnosed with autism spectrum disorder and severe developmental challenges.

Ascent's curriculum is grounded in Applied Behavior Analysis (ABA), focusing on functional communication, academic achievement, self-care skills, and behavior reduction. Certified special education teachers, Board Certified Behavior Analysts (BCBAs), speech-language pathologists, occupational therapists, and physical therapists work collaboratively to design individualized education plans (IEPs).
