Most NASCLA prep on the market is text-heavy and generic. TCS narrates the course in a working contractor's voice from the kitchen-table side of the table — slow on every citation, anchored in real field stories from a multi-state master electrician who qualifies a contracting company. Every chapter comes with narration, slides, and practice questions, and the course ends with a certificate.

• •Universal core authored verbatim from the NASCLA Contractors Guide 14th Edition (sub-topic citations to chapter and page).
• •280+ practice questions in the exam's format ship with the course (20 per chapter).
• •Per-state overlays cover the four buckets every exam tests and every contractor needs: state taxes, mechanics-lien deadlines, labor laws, and state-specific contract rules.
• •PDF certificate on completion. Renewable on the NASCLA Guide's ~2-year edition cycle.

14 chapters. ~3 hours of audio. Open-book exam-day ready.

The NASCLA exam, given by PSI, is open-book. We tab the citations and walk every load-bearing formula slowly enough to keep up with the calculator. Every chapter ends with 20 questions in the exam's format and a knowledge check that mirrors the format you'll see at the test center.

Pre-filled state overlays — built once, applied to your state.

Universal NASCLA content is the same in every state. State law isn't. We layer your state's specific rules on top of the universal core: state income/sales/contractor tax, mechanics-lien filing deadlines, workers' comp threshold, prevailing-wage rules, prompt-pay statute, retainage caps. Same build pattern as the TCS state-CEU library — every state gets its own treatment so you only see your state.

Don't see your state? Email us — support@tradecodesolutions.com — and TCS moves it up the list based on demand.

One state's course is $79 at launch, and each added state is $19. Course price only; no state fee applies. Your exam and application fees are paid to PSI when you register.

The $79is for the prep course only — you'll still bring your own tabbed copy of the NASCLA Contractors Guide to the open-book exam. The practice-test bundle ($199 with the NEC Journeyman Prep course) is for the NEC trade portion, not the NASCLA business-and-law content.
