- NTN written test — approximately two hours through the National Testing Network.
- CPAT — the eight fireground events; Denver treats it as a core gate.
- Background investigation, polygraph/integrity steps, and interviews per the commission's process.
- Medical and psychological evaluation, then the DFD academy — EMT certification must be obtained and maintained.

- The CPAT: Denver's altitude makes conditioning honest. Follow the CPAT training plan and read why people fail the CPAT.
- The interview and background: the commission process is document-heavy — get ahead with the background check and psych eval guide, and rehearse the firefighter oral board.
