About Us

Contractor School Online has over 25 years of experience.

Contractor School Online® (CSO) is the premier educational provider, offering in most states and the District of Columbia, quality training to prepare you for your Contractor License Exams. We're a National Company and carry Construction Books, CD's, DVD's, and more. We have served corporations both large and small, as well as individuals, to obtain their contractors or specialty license in the states that require a state license.

CSO can assist you with practice exams and home study courses in most states that require a state contractor's license. The materials we carry are what that state suggests you read, before taking the state tests.
