THE PRESENT INVESTIGATION HAD A THREEFOLD OBJECTIVE--(1) TO DISCOVER THE EFFECTS OF FREQUENCY AND PATTERN OF FAMILY MOVES ON PUPILS' HIGH SCHOOL ACHIEVEMENT TEST SCORES, (2) TO DISCOVER THE EFFECTS OF FREQUENCY AND PATTERN OF FAMILY MOVES ON THE GRADES PUPILS EARNED IN HIGH SCHOOL, AND (3) TO DISCOVER THE EFFECTS OF FREQUENCY AND PATTERN OF FAMILY MOVES ON PUPILS' PARTICIPATION IN EXTRACURRICULAR ACTIVITIES. HISTORICAL APPROACH WAS CHOSEN FOR THIS INVESTIGATION. STARTING WITH THE END-PRODUCT OF PERFORMANCE DURING THE LAST 2 YEARS OF HIGH SCHOOL, THIS PERFORMANCE WAS TRACED BACK TO DIFFERENCES IN FREQUENCY AND PATTERNS OF PREVIOUS FAMILY MOVES FROM ONE PLACE OF RESIDENCE TO ANOTHER. MOVING BETWEEN COUNTIES AND STATES FROM 1 TO 10 TIMES, IN ANY OF SEVERAL PATTERNS, IS NOT CONSISTENTLY FOLLOWED BY SIGNIFICANT DIFFERENCE IN CHILDREN'S PERFORMANCE IN HIGH SCHOOL EXCEPT IN THE AREA OF STUDENT ACTIVITIES. THERE SEEMS TO BE A SLIGHT TENDENCY TOWARD LESS INVOLVEMENT IN STUDENT GOVERNMENT, CLUBS, SPORTS, AND THE LIKE AMONG STUDENTS WHO HAVE BEEN UPROOTED DURING THE SECONDARY GRADES. AREAS FOR FURTHER STUDY INCLUDE REASONS FOR MOVING, EXPECTATIONS AND THE DEGREE TO WHICH THEY WERE CONFIRMED BY THE NEW PLACE OF RESIDENCE, AND THE AMOUNT OF CULTURAL DIFFERENCE BETWEEN THE OLD SCHOOL AND COMMUNITY AND THE NEW.
