AT assessment costs will vary depending on numerous factors, including the extent of solutions sought or time required for observations/technical assistance. Formal AT assessments with a written report generally range from $1500 to $2500 plus travel. As OATC considers the needs of the AT assessment request, we will provide an estimate to the district. After OATC considers the specific needs and provides a cost estimate, school districts may submit a purchase order prior to OATC scheduling the initial assessment visit.
