How exam scheduling works
- Apply to the state board first. Most providers will not allow you to schedule an exam until the board has approved your application and issued an Authorization to Test (ATT) letter. The ATT contains a candidate ID required to book the seat.
- Download the candidate information bulletin (CIB) from the provider portal. The CIB lists the exact reference materials (NEC edition, IBC edition, NASCLA business book) you may bring to the open-book portion.
- Schedule online. PSI, Prometric, and Pearson VUE all use real-time seat-selection systems. Available dates vary by program and test center.
- Pay the provider directly. Exam fees are separate from the state application fee and are non-refundable on the day of the test if you do not show.
- Bring two forms of ID, your ATT letter, and the approved reference materials. The provider will deny entry without a primary government-issued photo ID.
- Receive a pass/fail score sheet at the test center. Follow the program instructions for score reporting and any required transcript request.
Provider assignments change when state boards renew their testing contracts (typical cycle: 3–5 years). The directory above is generated from the state license guides, which are scheduled on a 90-day review cycle and show their last completed source-check date. Always confirm the current provider directly with the state board before paying any exam fee.
