This study reports short-term outcome evaluation results of a school-based peer counseling (PRC) program as implemented by North Forsyth High School during January 1990-February 1991. The PRC program is evaluated in terms of: 1) the content of the program as evaluated by the PRC trainees; 2) the quality of the PRC instructor as perceived by these trainees; 3) several instrumental objectives deduced from the PRC training program; and 4) the degree to which the program was able to reach other students at North Forsyth during the time the PRC was in operation. In the absence of a control group, the treatment effect of the program is determined in terms of individual growth curve models. Through the multiple evaluation designs employed in this research, it has been learned that a significantly larger proportion of students in the PRC group had more favorable attitude toward the content of the PRC program when compared to the content of what they learned from their regular school curricula. Furthermore, a significantly larger proportion of students in the PRC program reported more favorable attitude toward their instructor than their regular school teachers. The PRC program was able to elicit an improvement of trainee self-esteem (p less than .01) and their social values (p less than .05) between pre and post of the Peer Training Evaluation Instrument. In terms of client access, 18.4 percent of the totality of potential clients at North Forsyth have been reached through sixty-one peer counselors sanctioned by the school.
