Data Processing Systems for School District Testing Offices. Publication No. 77.41.
Watkins, James; Wilkinson, Leon D.
A poorly designed data processing system in a school district testing office may cause a delay in the creation of test results, produce inaccurate results, or utilize more resources than are necessary. Therefore, the authors present a model of a data processing system as a basis for comparing systems in terms of the basic functions they must perform and the constraints under which they might operate. Optical scanning, editing, scoring, and creating reports and output files are the four functions which comprise the model, and the operation and interaction of each is outlined. The external constraints which are found in data processing systems are the resources available for use by the system, and the demands that are placed on the resources. These demands involve: (1) generating specified reports and tape files for later use; (2) insuring a specified degree of accuracy in the data; and (3) completing reports by a specified date. Creating a balance between system resources and demands is discussed. In addition, flow charts for the overall system and each of its functions are appended. (Author/JAC)
