If you are scheduled to take the CBLE (Customs Broker License Exam) on October 26th make sure to check if your test site has a vaccine or mask mandate. Here is the notice from the CBP website.
NOTICE: Given the evolving COVID-19 situation examinees are responsible for checking the PDRI/PSI COVID-19 page (https://www.psionline.com/important-notice-update-concerning-covid-19-c…) regularly to find out if there is a vaccine or mask mandate at the registered testing site. It is THE EXAMINEE’S responsibility to stay up to date. CBP will NOT provide refunds for those who are not able to test as a result of being uninformed or noncompliant about the COVID-19 policy. CBP and PDRI/PSI recommend that the examinee checks the website regularly leading up to the exam, including the night before the CBLE.
Best of luck!
