An Exam Drill Agent for Journeyman Candidates

Timed practice sets in the real exam format — 70 questions, weighted toward the topics the candidate keeps missing — delivered in the short gaps of a field day instead of relying on study time that never comes.

The problem

The journeyman exam is a code-book test as much as a knowledge test: in many jurisdictions it's 70 multiple-choice questions in about three and a half hours, open-book against the current NEC, pass mark around 70%. Working electricians fail it less from not knowing the trade than from never having practiced finding answers in the book under a clock — and from study plans that assume free evenings a field schedule doesn't have.

Commercial prep gets expensive, generic question banks don't track what an individual candidate is weak on, and a missed topic — grounding and bonding, conductor sizing, motor calculations — keeps costing points across dozens of questions without ever being named as the problem.

How the agent workflow works

1. The agent is loaded with the exam's ground rules: question count, time limit, passing score, the code edition being tested, and the topic weighting of the official content outline.
2. Short drill sets — five to ten questions — are sent at scheduled points in the day: before shift, lunch, end of day. Each question cites the code article the answer lives in, so looking it up is part of the drill.
3. Every answer is scored by topic. The agent tracks accuracy per topic over time, so "weak on grounding" is a measured fact, not a feeling.
4. Set composition adapts: weak topics get more questions, strong topics get maintenance-level exposure, and previously missed questions come back at intervals until they're answered right twice in a row.
5. Periodically the agent runs a full timed mock — the real question count, the real clock, no pausing — and reports score by topic against the pass line.
6. A simple study plan view shows days to exam date, sets completed, and the two or three topics currently deciding pass or fail.

What you need to set it up

• The exam specifics for the jurisdiction: code edition, format, time limit, pass mark, and the publisher's topic outline.
• A question source the candidate trusts — a licensed prep bank or a vetted set — with code references attached.
• A phone and a messaging channel for delivery and answers; drills have to be answerable one-handed, standing in a trailer.
• A fixed exam date. The scheduling and the weighting both key off it; "someday" candidates get nothing from this.

Where it breaks

Question quality is the whole risk. Agent-generated practice questions can be wrong — wrong answer key, wrong code cycle, a distractor that's accidentally also correct — and a candidate drilling bad questions is training errors with confidence. Any question set needs vetting against the actual code book, and disputed answers should resolve to the printed article, not the agent. The agent also can't reproduce exam-day conditions: the testing center, the unfamiliar copy of the code book, the proctor rules on tabs and highlighting. And drills measure recall and lookup speed, not judgment — a candidate can ace sets and still freeze on a multi-step calculation they've only ever seen in short form. Full timed mocks with a physical code book remain non-negotiable.

The bottom line

Best for working electricians with a booked exam date and no study time to protect. The agent's contribution is logistics and honesty: practice that fits a field day, and a running, topic-level picture of where the pass is actually won or lost. It replaces the scheduling problem, not the studying.
