This paper is a discussion of the research, design, and implementation of an interactive testing program that was written in VAX-BASIC, and implemented on a VAX-11/780. Computer-assisted test construction and administration are discussed. Free response test items and response selection test items are discussed and implemented as are test, student, and item analysis statistics. The program allows the user to enter, change, delete, or add, question stems. correct answers, and incorrect answers. The program will randomly select questions and appropriate answers from the created test bank. It will either administer and score the test interactively, or produce a printed copy of the test along with an answer key. A statistical package allows the user to produce grade reports and item statistics. The program allows a professor to develop, and administer high quality test. / Master of Science
