This manual addresses the Comprehensive System of Personnel Development (CSPD) requirement of Public Law 94-142. It presents model procedures for the collection of data necessary to project personnel needs in special education. Implementation of the model will identify: areas of education which show need for additional teachers as well as areas of surplus; ages at which teacher attrition is most likely to occur and the rate of attrition in different teaching fields; and employment opportunities of newly trained teachers for the state. The model also provides information on: the pool of newly prepared teachers available for positions; the need for and availability of teachers with minority backgrounds; the sources of all newly hired teachers in the state; the age, gender, and educational level of all newly hired teachers; and the reserve pool of teachers available to fill vacancies. It also investigates whether noncertified teachers complete their certification requirements and how long they remain in education, and examines the differences between rural and urban education services. The manual provides a rationale for use of the model, guidelines on application of the personnel assessment procedures, and guidelines on assessment of inservice needs. (JDD)
