A generalizable systems-based needs analysis model was developed to help school district testing and evaluation offices evaluate current problems with their information processing systems and identify additional computer capabilities required to upgrade their systems. The model contains four main phases, namely: definition of the department function and operations; implementation of a needs analysis; analysis of specific problems and potential solutions; and development of a computer network model to alleviate the verified problems. Areas covered by the model include computer software, computer system components, prototype model evaluation, allocation of personnel, computer capabilities, problem and solution inspection, and development of a network model. The model was implemented with the Pinellas County (Florida) School District Department of Program Evaluation and resulted in a cost-effective prescription for improving its current computer capabilities. One important feature of the needs assessment model was the involvement of staff members at each stage of the study. By the time the final proposal was made, staff members could clearly see that it addressed their needs. Three figures and one table are included. (TJH)
