Progress on the University of Texas personalized system of instruction (PSI) project is described. Twelve courses in the College of Engineering and five in other colleges were developed for PSI under a grant from the Alfred P. Sloan Foundation. Each of those courses has now been offered at least once, thus making it possible to begin evaluating the program. Nine questions on the effectiveness, efficiency, student and faculty acceptance, and longer term utility of PSI are discussed. (DGC)
