This study evaluated a procedure for teaching three developmentally disabled adults to compute monetary change combinations. Also, the procedure assessed generalization to the skills of computing change with bills, verifying the correctness of change received, and computing change with both coins and bills. Subjects were first trained to make change using pennies and then were trained to use each successive denomination in combination with those previously trained. A multipleprobe design was used, including generalization probes of the above-cited skills. Results indicated that each subject acquired the behavior of change computation with coins as a function of the training procedure. Also, the change computation skills generalized to computing change with bills, excluding $20 bills which required additional training. Additional data suggested generalization to verifying change received and computing change using both coins and bills . Weekly follow-up data suggested maintenance of these skills following the termination of the training.
