American Computer Science League (ACSL)
The American Computer Science League offers computer science contests and computer programming contests for middle and high school students. We host these competitions at our school and offer classes to help students gain confidence and success. We field teams in two divisions: the Intermediate Division and the Senior Division for grades 9-12. Students interested in the Intermediate or Senior division must be enrolled in CSR-ACSL1 or CSR-ACSL2. Students in the Intermediate/Senior division are required to be proficient in Python (CSR-340 or equivalent is a prerequisite). Learn more about ACSL at the ACSL website.
Continental Mathematics League (CML)
The Continental Mathematics League offers computer science and math competitions for students in grades 3 through 8 which we host at our school. We offer classes to help students prepare for both the CML and Math Kangaroo contests. No experience is required, but students must be enrolled in our competition classes. CSR classes run September — June: CSR-COMP1 for grade 3, CSR-COMP2 for grade 4, and CSR-COMP3 for grades 5-6. Learn more about CML at the CML website.
Math Kangaroo
Math Kangaroo offers an international math competition held once per year in March which we host at our school. This contest is a lot of fun, with interesting and clever problems that students enjoy tackling. Students may participate in the Math Kangaroo competition at our school without enrolling in a CSR class. However, we offer an excellent series of classes to help young students build confidence and success with this competition. CSR classes run September — June: CSR-COMP1 for grade 3, CSR-COMP2 for grade 4, and CSR-COMP3 for grades 5-6. Learn more about Math Kangaroo at the Math Kangaroo website.
We also offer workshops specifically to help young students build confidence and success with the Math Kangaroo competition.
Our Math Kangaroo workshops are limited to 10 students and cost $60 per student (no registration fee required). Our next sessions are TBD
