Take a COF Test 

You can take the test at FDNY headquarters in Brooklyn. No appointment is necessary for walk-in hours (Monday to Friday from 9 AM to 2:30 PM).

If you can’t make walk-in hours, call (718) 999-2000 to schedule an appointment. 

You must bring:

  • An application
  • A government issued ID
  • $25 test fee (payable by cash, check, money order, debit card or credit card)

You should also bring a dated and signed letter of recommendation from your employer. It must state what type of dangerous work you perform.  You can still take the test without a letter from your employer. You will receive a temporary letter stating that you passed your exam. 

You will receive your test results immediately after your exam. If you pass the exam, you will also receive your COF card.


Most COFs are valid for 3 years. COFs can be renewed online, in-person, or by mail.
