 ## NWB Enhancement Proposal (NWBEP)
 
-NWB Enhancement Proposals (NWBEP) are the formal process for proposing additions or significant changes to the NWB standard. They are used when a new feature, data type, or change is broadly useful to the community and should become part of the official NWB specification. NWBEPs undergo a structured review and approval process facilitated by the NWB Technical Advisory Board (TAB) to ensure quality, consensus, and long-term maintainability. NWBEPs often leverage NWB extensions (NDX) as a testing ground, to implement and evaluate proposed changes first as an NDX to allow the community to use, test, and refine the extension in real-world scenarios. This process helps ensure that proposals meet community needs and are robust before being considered for inclusion in the core NWB standard. See the below resources to learn more about NWBEPs:
