In 2007–2008, 2009–2010, Sands won the Fraser Valley Badminton Championships. The school also has a Field Hockey team and as of September 2010, features an Ice Hockey team.

Sands Secondary runs on a linear system like other Canadian high schools. It is based on 8 courses separated into four days. For example, if Monday is a day 1 then Tuesday would have to be a day 2. Each day contains 4 blocks numbered ABCDEFGH. Day 1 contains A B C D block, while day 2 contains E F G H. Day 3 contains B A D C block. Day 4 contains F E H G block. Between B and C block there is a 45 min lunch break, as well as F and G block. Due to the Covid-19 pandemic, a new schedule was implemented. The 2020-2021 school year used a quarter system, where students had 2 classes a day. Each course had a 2-hour block, and the school day ended after those two courses. In the 2021-2022 year, a semester system is in effect.
