建筑与技工
Contractor (CSLB), electrician, plumber, HVAC and other skilled-trade license exams.
Contractor licensing exams are required to work as a licensed contractor. Most states test business and law knowledge — contracts, licensing rules, safety, employment and finance — alongside trade-specific skills, and many states accept the multi-state NASCLA exam. This hub gathers every contractor licensing exam PrepPass covers, from California's CSLB exams to state contractor exams and NASCLA, so you can practice the exact exam your state board requires. Practice questions and mock exams are free.
Skilled-trade license exams certify electricians, plumbers and HVAC technicians and cover the codes and safety rules those trades work under. This hub gathers the journeyman and master trade exams plus core certifications like EPA 608 and OSHA 30 so you can practice for the credential your trade and state require. All practice questions and mock exams are free.
