The Rural Outreach Chemistry for Kids (R.O.C.K.) program was designed as a service-learning project for students at Saint Francis University to serve the local communities by organizing chemistry activities in high schools. It was initiated in 1995 and has involved a large number of Saint Francis University students and local high school students. This article presents an evaluation of the R.O.C.K. program and discussion of its findings. The evaluation was conducted using multiple evaluation designs to assess the impact of the program on high school students' interest in science and Saint Francis students' learning process and their views on service-learning. The results indicate that the program was effective and had positive impact on both high school and Saint Francis students who participated.
