There is no autism-specific school in Bangor, and it is better to say that plainly than to pad a list. What Bangor does have is a district with a board-certified behavior analyst on staff and special-needs programming in every school - plus access to Maine''s district-funded special purpose private school system if that is not enough.
District special education with programming in every school, a school psychologist, social workers, a board-certified behavior analyst on staff, and OT, PT and speech-language services.
State list and oversight of approved special purpose private schools used as district-funded out-of-district placements. Most are in southern Maine, so factor in travel.
