The NRF is written around what DHS labels five core principles:

• Engaged partnerships at all levels of government and across public and private sectors
• Tiered response whereby local communities, tribes and states have the primary responsibility for the safety of their citizens;
• No two disasters are alike, meaning all capabilities have to be flexible and adaptable to meet the needs of every unique event;
• Unity of effort, meaning a clear understanding of the roles and responsibilities among all those involved;
• The plan must be always be in an active, forward-leaning posture that emphasizes readiness to act.
