This manual presents procedures for collecting data to project personnel needs in the field of special education, addressing in part the Comprehensive System of Personnel Development requirements of Public Law 94-142. Implementation of the procedures identifies: areas of education that 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 teachers attrition in different teaching fields; employment opportunities for newly trained teachers; the pool of newly prepared teachers available for positions; the efficacy of employing teachers who are not fully certified; the differences between rural and urban education services; the need for and availability of teachers with minority backgrounds; a profile of the sources of all newly hired teachers in the state; the age, gender, and educational level of all newly hired teachers; and information for assessing the reserve pool of teachers available to fill existing vacancies. The majority of the data required can, in most cases, be generated from the state education agency's computerized database. 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. (12 references) (JDD)
