DURING THE SUMMER OF 1965, 5 AGENCIES SPONSORED A HEADSTART PROJECT FOR 4500 CHILDREN FROM THE GREATER CLEVELAND OHIO AREA. EFFORTS WERE CONCENTRATED ON ORGANIZING 5 ENDEAVORS. (1) THE DIRECTORS OF THE 5 AGENCIES WORKED TOGETHER TO ESTABLISH STANDARDS FOR PSYCHOLOGICAL EVALUATION PROCEDURES. (2) FROM 8 CENTERS, 125 HEADSTART CHILDREN AND 125 NON-HEADSTART CHILDREN WERE CHOSEN AT RANDOM AS SAMPLES IN A PROGRAM TO DEVELOP CLASSROOM OBSERVATION METHODS. (3) THE SAME GROUPS OF CHILDREN WERE TESTED ON THE PRE-SCHOOL INVENTORY AND PEABODY PICTURE VOCABULARY TEST BY PARENTS AND PSYCHOLOGY GRADUATE STUDENTS TO STUDY THE EFFECTIVENESS OF HEADSTART PARENTS AS ADMINISTRATORS OF PSYCHOLGICAL TESTS. (4) ALL 250 CHILDREN WERE TESTED DURING THE THIRD WEEK OF THE PROGRAM AND BEFORE THE END OF SCHOOL. DATA CONCERNING 50 SELECTED CHILDREN WERE GIVEN SPECIAL EXAMINATION AS A FOLLOWUP STUDY. (5) TWO SERVICE AND RESEARCH POSSIBILITIES DISCUSSED WERE A JOINT PROGRAM OF CLEVELAND AREA PEDIATRICIANS AND PSYCHOLOGISTS IN THE DETECTION AND SERVICING OF THE DEVIATING CHILD AND THE TRAINING OF PARENTS TO WORK WITH TEACHERS IN THE CLASSROOM.
