Magnet schools within Cleveland Metro SD. Early College is an initiative throughout the state. These schools I think are mandated to be associated with a University, better if on campus. They have as the name states, early college courses. Kids graduate sometimes with a couple years of credits already in the books. I had to google Campus International. That looks to be a K-8 feeder for Early College.
Had to ggogle a bit, Cleveland Municipal appears to have more than one Early College. Bard is on the westside and associates with Bard College. That's in NY. That strikes me as more of a charter school but the website says "Cleveland Municipal." Cleveland Early College is on the Eastside at John Hay and associates with Cleveland St, Kent and Kenyon. There's a 3rd nearer the center, Design Lab, which doesn't really seem part of the Early College program. Looks more to be pre-engineering.
Schools like this don't normally have their own teams. I believe kids would play for their designated district team.
