About Contractors State License Service, (CSLS)
Contractors State License Service (CSLS) is the largest school in California devoted to the Construction professional. For over 23 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 33 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 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 has continually operated under the oversight of the State of California’s Bureau for Private Post Secondary and Vocational Education (CA BPPVE) since its inception.
In addition to our proven licensing programs, CSLS also offers the following courses:
