Contractors State License Schools

Contractors State License Services (CSLS) is the largest school in California devoted to the Construction professional. For 25 years, CSLS has helped its students pass the exam to become licensed contractors in the State of California, licensing more students than any other school.

From our main offices in Southern California, CSLS operates over 25 locations with full-service support and classrooms.  We have grown to this extent by providing quality, professional services.  In comparison, this provides 7 times the number of convenient locations than the second largest contractor school. 

Contractors State License Services 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. Contractors State License Services formerly operated under the oversight of the State of California’s Bureau for Private Post Secondary and Vocational Education. As of January 1 2010, the new Bureau for Private Postsecondary Education (BPPE) came into existence replacing the BPPVE. CSLS now operates under the provisions of the California Private Postsecondary Education Act of 2009 (CPPEA), Article 4 Section 94874(f).

In addition to our proven licensing programsCSLS also offers the following courses:
