COVID-19 statement
Many NRCC certificate holders and Board members are on the front lines of the COVID-19 crisis.
We’d like to provide a status report for anyone intending to apply for certification, in the application process, ready for an exam, or looking to renew their certification. Our office is open since nearly all our work is done electronically. We are processing applications, reference forms, transcripts, and renewals quickly. The two aspects of our operations that have slowed down a bit are application reviews by the credentials committee (many of our Board members are actively involved in the COVID-19 response) and exam scheduling. While exams are administered electronically, we still require an in-person proctor. Unfortunately, most commercial testing centers, university testing centers and public libraries are closed for the duration of the pandemic. If you need to schedule an exam, please correspond with the office so we can make sure an acceptable proctor is available. You might consider spending the waiting time studying, however! Please feel free to contact us with any questions or concerns, and please stay safe.
