Texas TDLR Journeyman Room
Since March 11, 2025 the TDLR Journeyman Electrician exam is two separately-scored parts: NEC Knowledge (59 questions, 130 minutes) and Calculations (26 questions, 110 minutes). You need 70% on each part, and the two are timed and scored independently. Both parts are open book against your own NEC 2023.

Answered questions in this room
Can I bring my own NEC book to the TDLR exam?
You bring your own NEC 2023 to the TDLR exam. It must be soft-bound. Notes, highlighting, and permanent publisher tabs are allowed only if added before the session. Loose-leaf, spiral, ring-bound books, homemade tabs, loose paper, and the NEC Handbook are not allowed.
Is the TDLR Journeyman exam open book?
Yes. Both parts of the TDLR Journeyman exam are open book against your own soft-bound NEC 2023. Open book does not mean easy. You still have 26 calculation questions in 110 minutes and 59 knowledge questions in 130 minutes, so the exam is won on how fast you find rules, not on having the book.
