THE PURPOSES OF THIS PILOT PROJECT WERE (1) TO ATTEMPT TO EVALUATE THE EFFECT OF THE LOCAL PROGRAM ON BOTH INDIVIDUAL CHILDREN AND THE GROUP AND (2) TO INVESTIGATE THE SENSITIVITY OF THE TEST INSTRUMENTS EMPLOYED IN EVALUATING SUCH A PROGRAM. SIXTY-ONE CHILDREN WERE ENROLLED IN THE LOCAL HEADSTART PROGRAM AND WERE ADMINISTERED THE STANFORD-BINET, LEITER INTERNATIONAL, RAVEN PROGRESSIVE MATRICES, AND PEABODY PICTURE VOCABULARY TESTS. IN ADDITION, 20 CHILDREN, SELECTED AT RANDOM FROM THE GROUP WERE TESTED BOTH BEFORE AND AFTER THE PROGRAM. RESULTS INDICATE (1) STATISTICALLY SIGNIFICANT IMPROVEMENT IN PERFORMANCE FOR THE 20 CHILDREN, (2) SIGNIFICANT CORRELATIONS AMONG THE VARIOUS TEST SCORES OF THE TOTAL GROUP, AND (3) PARTICULAR SENSITIVITY OF THE LEITER AND PEABODY TESTS IN REFLECTING CHANGES IN FUNCTIONING. IMPLICATIONS OF THE STUDY FOR FUTURE HEADSTART PROGRAMS AND ALSO FOR FURTHER RESEARCH WITH CULTURALLY DEPRIVED CHILDREN WERE DISCUSSED. (CO'D)
