How does NBCOT verification work?
- Open Verify an OTR/COTA on nbcot.org.
- Enter the person’s last and first name and pick the country and state, or enter a certification number instead.
- Search, and read the result NBCOT returns.
NBCOT says the data is provided and maintained only by NBCOT, can’t be changed by anyone outside, and is checked by its staff. It also says it takes no responsibility for errors caused by technical problems.
Sending proof of your own certification
- A Verification of Certification letter, which confirms your status to a state board, employer or agency. You order it in MyNBCOT, and NBCOT lists it at no cost.
- A score transfer, which sends your exam score to a state board within three business days of your request.
- Your digital certificate, badge and wallet card, which NBCOT emails after you pass and after each renewal.
Before you’re certified: the eligibility confirmation notice
While you’re still waiting to test, NBCOT can send an eligibility confirmation notice to a state board or employer, confirming that your application, fees and academic documents are processed and that you’re approved to schedule. It’s often used for a temporary permit, but these 15 states don’t accept it:
- Alabama
- Arizona
- Colorado
- Hawaii
- Iowa
- Kansas
- Louisiana
- Michigan
- Minnesota
- Mississippi
- New Hampshire
- North Carolina
- South Carolina
- Washington
- Wisconsin
Certification lookup or license lookup?
NBCOT’s lookup shows national certification only. A state license is issued by the state board, so to check a license, go to that board. NBCOT’s state contact list has each one.
