EVALUATION STEPS WERE DEVELOPED FOR THE CURRICULUM CONTINUITY DEMONSTRATION (CCD), A JOINT PROJECT OF THE PITTSBURGH SCHOOLS AND THE UNIVERSITY OF PITTSBURGH. THE GOAL OF THE PROJECT WAS TO DEVELOP A COORDINATED EDUCATIONAL PROGRAM WHICH CONSTITUTES A TRUE CONTINUUM FOR THE STUDENT AS HE PROGRESSES FROM KINDERGARTEN TO COLLEGE. INITIAL EVALUATION BY MEANS OF STANDARDIZED TESTS, LOCALLY DEVELOPED TESTS, COMPARISON CONTROL GROUPS, AND EXPERT OBSERVERS LED TO A REASSESSMENT OF THE PROGRAM. A BASIC RATIONALE WAS DEVELOPED FOR CONSIDERING NEW PLANS--WHETHER THE INNOVATION IN THE CONCERNED SITUATION DOES WHAT IS DESIRED BETTER THAN ALTERNATIVES. REEXAMINATION OF THE EVALUATION PROGRAM IN LIGHT OF THIS RATIONALE BROUGHT NEW STEPS IN EVALUATION--(1) MORE CAREFUL AND DETAILED SPECIFICATION OF CCD COURSE OBJECTIVES, (2) DEVELOPMENT OF NEW TESTS AND EVALUATION DEVICES, (3) ADMINISTRATION OF THESE TESTS AND ANALYSIS OF RESULTS, AND (4) UTILIZATION OF INFORMATION OBTAINED. ALTHOUGH OTHER PROGRAMS WILL REQUIRE OTHER STEPS, THE RATIONALE OR SOME MODIFICATION OF IT CAN SERVE TO GUIDE THE THINKING OF PERSONS RESPONSIBLE FOR A NUMBER OF TYPES OF EVALUATION EFFORT. THIS ARTICLE IS A REPRINT FROM "THE SCHOOL REVIEW," VOLUME 74, NUMBER 2, SUMMER, 1966, AND WAS PRESENTED AS A PAPER AT THE ANNUAL MEETING OF THE AMERICAN EDUCATIONAL RESEARCH ASSOCIATION (CHICAGO, FEBRUARY 10-13, 1965).
