This report presents the results of a 3-year study conducted by an external evaluator to assess the performance of HRSA grant programs in meeting the objectives of the CAAI. The study did not attempt to measure long-term outcomes, such as changes in the average age of first screening, because these impacts would generally not be discernible within 3 years. Instead, the study measured results of the grantees’ efforts in the areas of training, awareness building, research, and building comprehensive systems of care for ASD, all of which are expected to contribute to the realization of the CAAI’s long-term goal.
