As the largest contractors license school in California devoted strictly to construction professionals, CSLS has earned a reputation for service and quality instruction that is unmatched anywhere. For more than 25 years, we have helped more than 125,000 contractors and other professionals to become licensed, learn about their trade and run more efficient, profitable businesses. Although we feel confident in saying that we are the best construction industry school for contractors in the state – with more than two dozen locations – it’s the thousands of people whose dreams we have helped turn into reality that we are most proud of.

Our school isn’t just seven times larger than the next closest competitor, but it’s one of the few around that was formed by experienced builders and instructors, not legal or insurance professionals. So, when you want to learn the construction industry the right way, and put yourself on the path to success and higher earnings, try CSLS first and see why so many others turn to us every year.
