We are glad you found us. People generally look for Alsion after they have first checked out all the “brand name” schools and still found something lacking. Alsion is a small school, with a full time faculty of five highly qualified teachers serving a junior high community of only 48 students. As you might expect from a school with student/teacher ratio 10 to 1, students receive more personal Historically, three out of four Alsion Early College graduates have been accepted for admission to the University of California. This is an outstanding track record for any school, regardless of its size or reputation.

Alsion respects the individual and encourages students to embrace learning. Kids are happy here and there is not a bullying problem. They work hard at academics, teaming, partnering with others on projects, gardening and taking care of animals: chickens in our case. They can move on to Early College High School and graduate with a high school diploma and the equivalent of a 2 year degree recognized by the UC system.
