Which edition will my exam use?
Texas administers the Journeyman exam as an open-book test, and the codebook you're tested on is the edition TDLR has adopted on your exam date. The adoption date is fixed:
Study and bring the 2023 National Electrical Code. This is the current exam right now.
Study and bring the 2026 National Electrical Code. Section numbers and a few rules move — see below.
What actually changed for exam purposes
The 2026 NEC is a structural reshuffle on top of rule changes, so a chunk of the work isn't learning new code — it's re-learning where the code lives. For an open-book exam, that lookup-location change matters as much as the rules themselves. The changes most likely to show up on a Journeyman exam:
There's more in the full 2026 NEC — new EV power-transfer rules (Article 624), medium-voltage harmonization, cable-tray clearances — but those are largely outside the typical Journeyman scope. For the exam, the renumbering plus the 210.8 / 110.16 changes are the ones to internalize.
Watch the load-calc numbers, not just the article number. The 2026 edition didn’t only move load calculations from Article 220 to Article 120 — it changed the figures. General lighting and receptacle load drops from 3 VA to 2 VA per square foot, and the optional-method dwelling calculation now takes the first 8 kVA at 100% instead of the first 10 kVA. Same problem, different demand load — so if you learned the calculation half on the 2023 numbers and your exam is on or after September 1, drill the 2026 figures before test day.
What this means if you're studying right now
Don't overthink it, and don't buy two products to cover yourself:
- Testing this summer (before Sep 1)? Study NEC 2023. Nothing about the 2026 edition affects your exam.
- Testing in fall or later? You'll be on NEC 2026. Learn the new section locations early — the renumbering is the part that burns open-book time if you're hunting in the wrong chapter.
- Not sure of your date yet? Start on 2023 fundamentals (they don't change) and switch your section-lookup practice to 2026 once you schedule.
The catch nobody warns you about: buying your prep twice
Most exam-prep products are sold per code edition. Buy the 2023 set now, and when TDLR flips to 2026 in September you buy the 2026 set again. That's the normal model, and it's why the transition costs candidates real money.
We built ours the other way around. One $99 purchase covers the 2023 NEC question bank today, and the NEC 2026 update is included free when TDLR transitions on September 1. Buy once, and you're set through the change — whichever side of the line your exam falls on.

FAQ
When does the Texas Journeyman exam switch to the 2026 NEC?
September 1, 2026. Exams before that date use the 2023 NEC; exams on or after that date use the 2026 NEC. If your date is close to the transition, confirm with PSI when you schedule.
Do I need to learn the whole 2026 code from scratch?
No. The fundamentals don't change. The bigger adjustment is structural — several articles were renumbered (for example, load calculations moved from Article 220 to Article 120), so your open-book lookup habits need updating more than your knowledge does.
Do the load-calculation numbers change in 2026?
Yes — and this is the one most likely to cost you points. Beyond moving from Article 220 to Article 120, the 2026 NEC lowers general lighting and receptacle load from 3 VA to 2 VA per square foot and changes the optional dwelling method to take the first 8 kVA at 100% instead of the first 10 kVA. The same calculation problem yields a different demand load, so practice the 2026 figures if your exam is on or after September 1, 2026.
What are the biggest 2026 changes for a Journeyman?
The renumbering of Chapters 1–7, the expansion of GFCI protection under 210.8 to cover 125–250 V receptacles, and the removal of the 1,000 A threshold for arc-flash labeling under 110.16. New topics like EV power-transfer (Article 624) are mostly outside Journeyman scope.
If I buy prep now, do I have to buy it again for 2026?
With most products, yes — they sell per edition. With Journeyman Wireman, no. One $99 purchase covers the 2023 question bank now and includes the NEC 2026 update free when TDLR transitions on September 1, 2026.
Should I wait until the 2026 code drops to start studying?
No. If you're testing before September 1 you'll be on 2023 anyway, and even for a later test the fundamentals carry over. Starting now and switching your section-lookup practice to 2026 once you schedule is the efficient path.
