Founded in 2001, GMCHS is located on the Grossmont College campus and is run entirely by two teachers, a secretary and a counselor.

GMCHS is a WASC-accredited alternative high school, providing a bridge to college education and career training.

Juniors and seniors who are capable of succeeding at the college level and who are not challenged by traditional high school work have the opportunity to complete requirements for high school graduation while earning college credits and obtaining job experience.

These credits either fulfill high school graduation or college general education requirements, or both.

Classes taken from the community college generally count for both, but students may need to finish certain high school requirements.
