This investigation examined the potential impact of a school-based youth intervention program on the attitudes and behavioral patterns of at-risk youth. The sample size used in this study was 52; 24 participants received the school-based intervention and 28 participants did not receive the intervention. A two-group pretest-posttest design approach was implemented. A two-phase behavioral intervention was used with at-risk youth who were returning from a remanded period at an alternative school in lieu of expulsion from school. After the conclusion of the intervention program, school attitudes, behavioral indicators and academic success indicators were evaluated. The results of this study revealed that there was a significant treatment effect on youth’s school attitudes.
