Demographic characteristics were recorded and students completed a researcher-made questionnaire on puberty before, immediately after, and one month after the intervention. The intervention group received peer education on puberty by trained individuals for one month. Data were analyzed using descriptive statistics. The alpha level of 0.05 was considered significant. Results: There were no significant differences between the two groups in the mean scores for knowledge and practice before the intervention (P= 0.17). The mean scores of knowledge and practice in intervention group were 28.18±3.85 and 121.59±10.32 immediately after the intervention, and 31.91±3.69 and 130.37±8.07 one month after the intervention, respectively which were significantly higher than those of the control group (P= 0.001).
