News & Events

This morning Channel 7 Eyewitness News featured a story about a new Post-Graduate (PG) initiative at SEM beginning in the 2022/23 academic year. Our PG Program addresses a trend we noticed before the pandemic. High school graduates began to articulate a desire for a new academic experience before the beginning of their undergraduate careers. Some students expressed interest in more time for independent study; more time to explore new academic interests or particular intellectual passions; more time for immersion in the Arts; more time to cultivate athletic excellence; more time to explore future professional careers and community service opportunities. You can find a complete description of the initiative on our website PG Program.
