RECORDS WERE KEPT ON THE SUCCESS OF TECHNIQUES USED TO OBTAIN FOLLOWUP INFORMATION ON OCCUPATIONAL AND EDUCATIONAL STATUS OF 12,615 INDIVIDUALS 2 YEARS AFTER BEING TESTED IN GRADE 12. THE STUDENTS COMPLETED AN ADDRESS SHEET DURING THEIR SENIOR YEAR GIVING THE ADDRESSES OF THREE PERSONS WHO WOULD BE LIKELY TO KNOW THEIR LOCATION 2 YEARS LATER. EMPLOYMENT SERVICE PERSONNEL IN THE 19 STATES USED VARIOUS METHODS TO LOCATE THE STUDENTS FOR THE FOLLOWUP STUDY. MOST STUDENTS WERE REACHED THROUGH USE OF LETTERS. IT WAS FOUND TO BE WORTHWHILE TO SEND AS MANY AS THREE LETTERS, IF NECESSARY, BEFORE TRYING ANOTHER METHOD. HOWEVER, THERE WAS A STRONG RELATIONSHIP BETWEEN THE NUMBER OF TECHNIQUES USED BY A STATE AND THE STATE'S OVERALL SUCCESS. AMONG THE MOST SUCCESSFUL TECHNIQUES, IN TERMS OF THE PERCENTAGE OF ATTEMPTS THAT WERE SUCCESSFUL, WERE TELEPHONE CALLS, PERSONAL VISITS, USE OF EMPLOYMENT SERVICE RECORDS, AND PERSONAL KNOWLEDGE OF INDIVIDUALS IN THE COMMUNITY.
