NERIS — the National Emergency Response Information System
The system itself: what NERIS is, how it is structured, and the timeline departments are working to.

What fire department records systems do, how incident data moves from CAD into reporting systems, what changed with the transition from NFIRS to NERIS, and why fire departments should understand their data even when a vendor submits it for them.
Three systems get spoken about as if they were one. CAD documents the response. The records system documents the incident. NERIS creates a standardized national fire and emergency response data environment. Those systems may exchange information, but they are not the same thing — some information originates in CAD and flows forward, some has to be documented after the incident, and your RMS vendor sits between your department and the national dataset. That is worth understanding before you rely entirely on a vendor dashboard to tell you what your own department did.
