The 1972-73 accountability study of Duval County (Jacksonville, Florida) programs for trainable mentally handicapped (TMH) children and youth, funded under Title VI-B of the Elementary and Secondary Education Act, focused on the development and refinement of evaluation materials and field testing of the materials developed. Twelve teachers identified approximately 550 behavioral objectives with corresponding criterion test items and accompanying instructional suggestions. Field testing involved evaluation of the 550 behavioral objectives by teachers, parents, and community agency personnel, evaluation of student performance using criterion test items, and evaluation of the project products and activities by a three member panel of experts. Results of field testing supported such conclusions as the following; (1) that there is a high degree of correspondence between the importance attributed to skill areas by teachers, parents, and community agency personnel with social skills generally ranked highest and occupational skills lowest; (2) that project materials have a high probability of being used and correspond to teacher needs; (3) that the criterion test item approach to assessment of TMH student performance is inadequate; and (4) that there is need of additional behavioral objectives in the occupational skills area which take account of skills needed for success in sheltered workshop situations.
