How state certification pages and operator-study content are verified and maintained.
Current review baseline
The 18 state command centers were rebuilt from their linked official program sources and consolidated to remove thin, repeated pages. State forms, fees, vendor arrangements, and deadlines can change after review.
How to verify before acting
- Open the official link on the state command center.
- Confirm the credential and class required by the facility or employer.
- Use the current application or portal—not a downloaded copy from an old guide.
- Confirm exam approval, identification, calculator, formula sheet, and retest rules.
- Save current records and agency correspondence.
