Its site, adem.alabama.gov, carries the current eligibility rules, class structure, exam registration and renewal requirements. Requirements change; the authority's version is the one that counts.
The exam, and what actually decides it
Alabama uses the standardized WPI exams: 100 scored questions, 3 hours, pass at 70, and a formula and conversion table handed to you at the desk. The math is where candidates actually lose points, and not for lack of formulas: the skill is recognizing which formula the word problem wants, converting units cleanly, and holding pace. The math, concept by concept trains exactly that, and the method article gives you the drill.

- Confirm which exam series and class level applies to your role and system.
- Study the territory with the exam reference and the four series guides.
- Drill the math formula-first, then run timed sets at roughly ninety seconds a question.
