NO SIGNIFICANT RELATIONSHIP WAS FOUND BETWEEN PAROLE STATUS AND PARTICIPATION IN THESE COURSES. YOUNGER PAROLEES TENDED TO VIOLATE PAROLE MORE FREQUENTLY THAN OLDER PAROLEES, BUT THIS RELATIONSHIP WAS CONFOUNDED BY OTHER VARIABLES AND IN CERTAIN CASES DID NOT HOLD.

SUGGESTIONS FOR FURTHER RESEARCH ARE OFFERED. SUPPORTING DATA AND A LIST OF REFERENCES ARE INCLUDED. (AUTHOR ABSTRACT MODIFIED--LKM)
