INSIDE HIGHER ED. JUNE 20, 2013. California's community college system this week unveiled a new Web tool that provides average salary levels of graduates of the state's 112 two-year colleges. The Salary Surfer database includes wage data for graduates of degree and certificate programs in about 25 disciplines. It lists the median annual salary for students two years before, two years after and five years after earning a specific credential. In April the system released Web-based "scorecards" on student performance at each college.
