The Interdependent Support Service Model, a 3 year project operated by the Hennepin Technical Center (Minneapolis, Minnesota) was designed to evaluate and program for communication and motor needs of severely/profoundly handicapped students and to develop related inservice training for staff. First year activities included modifying existing assessment procedures and developing a total assessment package which was then used in the second year. In the final year of the project, training instructional staff to use project procedures was emphasized. Evaluation of inservices on communication, feeding, and sensorimotor development and attended by approximately 200 staff revealed overall satisfaction and pre-posttest information indicated significant gains in knowledge for teachers and aides. Evaluation of the impact on students produced equivocal results, although staff did demonstrate increased proficiency in writing measurable objectives as a result of project activities. Inservice Objectives and rating scales, knowledge tests for inservice, and assessment instruments are appended. (CL)
