Junior Solar Sprint (JSS) is a competitive program for 5th- to 8th-grade students to create a small solar-powered vehicle.

JSS competitions are sponsored by the Army Educational Outreach Program (AEOP), and administered by the Technology Student Association (TSA).

[6] Junior Solar Sprint competitions are held at the national-, state-, and some regional-level TSA conferences,[7] as well as other AEOP-hosted locations.
