Programs & Services

Research has shown that early identification of autism and intensive treatment leads to better functional outcomes for children. Research has shown the techniques of Applied Behavior Analysis (ABA) to be highly effective in promoting the development of new skills and the reduction of interfering behaviors in very young children diagnosed with autism spectrum disorders. Beacon ABA Services was established to provide critical diagnostic services and early intensive behavioral intervention (EIBI) for young children.

Early Childhood Diagnostic Services


Early Childhood Diagnostic Services are available for families who are enrolled in Early Intervention (EI) and are pursuing Early Intensive Behavioral Intervention (EIBI) from Beacon. These services can be initiated by completing our referral form on our website or by request from your EI Service Coordinator. Comprehensive diagnostic assessments are also available for clients transitioning from EIBI services and pursuing In-Home and Center-Based services from Beacon after the age of three.

In-Home Early Intensive Behavioral Intervention Services


In-Home Early Intensive Behavioral Intervention (EIBI) services are available for families enrolled in Early Intervention (EI) who have received an autism diagnosis from Beacon or elsewhere.  Beacon is one of the largest Specialty Service Providers for the Early Intervention Division of the Massachusetts Department of Public Health serving all areas of the Commonwealth. These services can be initiated by completing our referral form on our website or from your EI Service Coordinator in the EI client system.

Over the Age of 3 In-Home and Center-Based Applied Behavior Analysis Services


In-Home and Center-Based Services are available for children diagnosed with autism as part of a transition from services provided through Early Intervention at the age of three. These services utilize the principles of applied behavior analysis and are funded through insurance. The focus of the In-Home and Center-Based Services period is to provide children and parents with support in developing skills related to the core deficits of autism: communication, social skills and adaptive behavior, and work on pre-requisites for your child’s success in school. These services are available from the age of three and can continue until your child either meets clinical criteria for discharge or attends school full-time.
