The services of the Regional Prescriptive Instruction Center are evaluated using varied approaches. Student performance measures will be obtained in the areas of reading, spelling and mathematic skills, as well as behavior ratings in terms of classroom adjustments. These measures will be administered in a pre-post test fashion with a 60 school day interval operating. Teacher evaluation will be accomplished by PIC staff rating teachers on the extent to which they have implemented the individual prescriptive plan, and, also, teacher ratings of PIC services through questionnaires. Teachers receiving PIC in -service training will be asked to complete a familiarity-of-terms checklist both pre and post. Parent evaluation will be monitored by the use of a parent evaluation questionnaire. Various supporting objectives will also be evaluated through the use of cost-effectiveness analyses, description of psychoeducational characteristics of children receiving PIC services, and these characteristics which best predict academic improvement following PIC services. Other objectives addressed by the evaluation procedures are those assessing value to teachers of PIC criterion--referenced test data and PIC diagnostic/remedial reports and recommendations.
