Why is the Texas TDLR calculations part scored separately now?

Since March 11, 2025 the TDLR Journeyman exam is two separately-scored parts: NEC Knowledge and Calculations. They are timed and graded on their own, and you need 70 percent on each. The practical effect is that a strong code score can no longer carry a weak math score, which is why the Calculations part now fails the most people.

Two parts, two scores

NEC Knowledge is 59 questions in 130 minutes. Calculations is 26 questions in 110 minutes. Each is passed or failed on its own at 70 percent.

Why it matters for your study plan

Before the split, a high knowledge score could offset shaky calculations. Now it cannot. If calculations are your weak side, they can sink you no matter how strong your code knowledge is.

What to do about it

Treat calculations like its own exam. The most recent published pass rate on that part was 20.56 percent, the lower of the two. Drill the calc types one at a time until the setup is automatic.

Bottom line

Two parts, scored on their own. Your code score no longer covers your math, so train calculations like a separate exam.
