Transition to a new school for adolescent students can be challenging. Students who have difficulty navigating the transition to ninth grade are at an increased disadvantage academically and personally. Even students who approach the move with excitement often have unrealistic expectations of what is necessary for success. Overall, those who do well freshmen year are more likely to graduate from high school and contribute positively to their communities. This article outlines a program designed to promote high school transition success through a summer day camp program called CAT Camp named for the school mascot, the Wildcat. Students who attended CAT Camp demonstrated more success in their first year in high school with higher GPAs, better attendance, less course failures, and fewer discipline referrals when compared to those who did not attend the summer program. Implications for practice are included. (Contains 1 table.)
