Abstract	Rapid and direct communication between a computer and a student, with instructional material dynamically tailored by the computer for each student, has been practised for some time now, generally under the label of CAI - Computer Assisted Instruction. Although results from earlier, scattered use of CAI indicate that students using it reach predefined levels of mastery somewhat sooner, and with less variation in performance, we do not find widespread use of this technology in our schools. Although there are very likely many reasons for this, we believe that high cost (from 3 to 10 times more costly than traditional instruction) and uncertainty concerning CAI's range of application have significantly delayed its adoption.Considering the makeshift nature of good deal of the early CAI material (courseware), and the technology by which it had to be delivered (costly transmission lines, ill-suited computer hardware and software, and costly and inappropriate student consoles), it is surprising that performance wasn't worse. However, two of the more recent CAI systems, MITRE's TICCIT and the University of Illinois' PLATO IV, have been designed specifically in response to these earlier weaknesses. Their promise, plus the increasing need for more and better options and a brake to the rising cost for education, has motivated the National Science Foundation (Office of Computing Activities) to organize and support the development and classroom test of each system.The major purpose of the project is to provide government, industrial, and educational decision makers with:- cost and effectiveness data from TICCIT and PLATO IV instruction.- system and components - hardware, software, courseware, and test instruments - that might prove useful after the termination of the project.- documented insight into problems or opportunities for future research and development.To this end, the Foundation has awarded contracts (totalling \$10 M over a 4-1/2 year period) to MITRE, the University of Illinois, and an independent evaluator - The Princeton Educational Testing Service - for the conduct of the necessary activities. Preparations for the tests and evaluations got underway formally in February 1972. The strategies and plans governing the project are presented in the following sections.
