IPoly has a unique opportunity to partner with a local private high school, Southlands Christian. IPoly students may sign up to tryout for one of their competitive athletics teams. Southlands Christian competes in the following CIF sports: Football, Volleyball, Cross Country, Girls Soccer, Boys Soccer, Girls Basketball, Boys Basketball, Baseball, Softball, and Badminton. Cheer is also offered.

Students must contact Southlands Christian if interested in participating. Once team rosters are available, they are sent to IPoly. If a student must leave early for a game, they must be signed out of IPoly by an approved adult or the student must submit written approval to leave early.

A shuttle is provided to take students from IPoly to the practice games. However, parents must pick the students up from Southlands after the practice. For further information, contact Southlands Athletics at 909-468-9943 or visit https://southlandscs.com/high-school-athletics/.
