This study evaluated the effect of play therapy training on graduate students' limit-setting choices in play therapy and compared their reported choice of limits with the reported choice of limits of experienced play therapists. The results indicated a significant difference between pre-training and posttraining limit-setting choices of graduate students, with more limits being chosen after training. The limits selected by students after play therapy training were similar to those chosen by experienced therapists in past studies. After training, students selected limits most frequently in the areas of physical aggression against the therapist, physical aggression against equipment, and on behaviors which endangered the child's health and safety. After training, students chose the fewest limits in the area of socially unacceptable behavior, particularly in the expression of obscenity in the playroom.Most play therapists agree that some form of limit-setting is essential to the facilitation of the therapeutic process (Axline, 1969;Bixler, 1949;Guerney, 1983; Landreth, 1991). A perplexing struggle for beginning play therapists, however, is how to maintain an accepting attitude and yet protect the child, therapist, and play materials from the child's destructive behaviors.The ability of play therapists to distinguish symbolic "destructive" behaviors from aggressive or destructive acts and to recognize and accept the child's wish or desire to act out such behaviors perhaps begins with the process of the play
