What is California's incident management system called?

• A. SEMS
• B. NIMS
• C. ICS
• D. ESF

Answer: (A)

SEMS stands for Supplemental Emergency Management System, and this is California’s incident management framework. It provides a unified command structure that coordinates response across local jurisdictions, the operational area, regional, and state levels, ensuring that people, information, and resources flow smoothly during emergencies. SEMS is built to be compatible with the national Incident Command System (ICS) and the National Incident Management System (NIMS), but it is the California-specific name for the system used to manage disasters and enable state funding and mutual-aid processes.

Understanding the others helps place SEMS in context: NIMS is the nationwide standard adopted across many states; ICS is the field-operations structure used within SEMS and NIMS; ESF, or Emergency Support Functions, organizes federal response by function rather than serving as the incident management system itself.
