The CSLS Difference

Contractors State License Service is one of the only contractor schools in the state that is run by educators, not lawyers or people mostly interested in the bonding and insurance business. Most importantly, CSLS operates under the provisions of the California Private Postsecondary Education Act of 2009 which is administered by the Bureau for Private Postsecondary Education.
