SST offers a four-year programme culminating in the GCE O-Level certification for capable and talented students who would excel in the fast-paced learning environment in SST.  SST admits all students through the Direct School Admission Secondary (DSA-Sec) Exercise and does not participate in the Secondary 1 (S1) Posting Exercise. SST admits up to 200 students in Secondary 1. Current Secondary 2 students can also apply to join SST through SST Year 3 Admission Exercise, subjected to vacancies.

At SST, the Applied Learning approach encompasses learning that is active and relevant, authentic, integrated, community focused, learner-centered, and process-focused. As such, students applying to SST are evaluated by a range of criteria and through different evaluation processes as appropriate for each level of entry.
