St. Andrew’s provides opportunities for students to pursue interests and develop talents outside the classroom. Through a varied co-curricular program, St. Andrew’s encourages students to exercise self-sufficiency, responsibility, and leadership, and to express themselves intellectually, socially, creatively,spiritually, and athletically.

Trips
When kids come together in a different environment, they see one another in new ways and can see new possibilities. Each year, 6th, 7th and 8th graders enjoy fall getaways. There is also a challenging fall "Leadership" weekend, available to students in 9th to 12th grades. Upper School spring sports teams often use Spring Break for travel and practice on warm weather fields.

Athletics
Students can choose to participate in varsity and junior varsity sports as well as several non-competitive physical education options.
