ASIM Advanced (PER-353) Active Shooter Incident Management Training

Who ASIM Advanced is for

ASIM Advanced (PER-353) is a 3-day, 24-hour, high-fidelity simulation course that stress-tests an agency or region's active shooter / hostile event plan under real pressure. Over three days, up to 60 participants across police, fire, EMS, dispatch, and emergency management run 10 complete simulated incidents using the ASIM Checklist, rotating through key positions until the priorities and actions become second nature. The course goes beyond tabletop discussion and forces leaders to make and communicate decisions at operational tempo, so you can see how your plan actually performs when the clock is ticking.

ASIM Advanced is developed and owned by the National Center for Integrated Emergency Response (NCIER®), the training division of C3 Pathways, Inc., and is built on the ASIM Checklist first published in 2013. The course is delivered nationwide by NCIER master instructors, both directly for agencies and on behalf of select National Training Providers under DHS/FEMA and related programs. In all cases, the same NCIER team delivers the training, ensuring consistency with the original ASIM methodology and the readiness benchmarks used in the broader ASIM Readiness system.

What's in the course

ASIM Advanced is a 24-hour, 3-day in-person course for up to 60 participants that brings your full team into the same room and the same incident. Law enforcement, fire/EMS, dispatch, PIO, emergency management, and air assets work together in a high-fidelity 3D simulation environment to run 10 complete incidents from first call to last transport. Participants rotate through ASIM Checklist roles to build real, position-specific experience, while the simulations surface command, communication, and coordination gaps before a real event. Each delivery includes structured after-action reviews and records so leaders can document gaps, improvements, and readiness progress for internal and external stakeholders.

  • 24-hour simulation-based course
  • 10 ASIM simulation exercises
  • Integrated police / fire / EMS / dispatch / aviation / PIO / EM roles

Key learning objectives

  • Describe the profile of a typical Active Shooter Event (ASE) and practice the model response process using the Active Shooter Incident Management (ASIM) Checklist.
  • Apply key leadership roles and functions within an Active Shooter Event response, including coordination across law, fire/EMS, dispatch, and emergency management.
  • Demonstrate response and management of Basic Complexity and Moderate Complexity Active Shooter Events in simulation-based practical exercises.
  • Demonstrate response and management of Complex Coordinated Attacks (CCA) in simulation-based practical exercises.
  • Demonstrate response and management of Moderate Complexity ASEs that include IEDs and/or an attacker who becomes static, barricades, or takes hostages in simulation-based practical exercises.
  • Discuss case studies of multi-modal Complex Coordinated Attacks (CCA) and connect lessons learned to local plans, policies, and training.

Also listed as…

Our National Training Providers list this same ASIM Advanced course under their own catalog titles and program structures, but the underlying content, ASIM Checklist, and NCIER instructor team are the same. When you see any of the names below in TEEX, ALERRT, or DHS/FEMA catalogs, you are looking at the NCIER-developed ASIM Advanced (PER-353) course.

Where you can take ASIM Advanced

ASIM Advanced is developed and owned by NCIER®, and the same NCIER master instructor team delivers every class. Agencies can host the course as an on-site "mobile delivery" at their own location, whether they contract directly with NCIER or access it through DHS/FEMA, TEEX, and ALERRT program channels.

Results & proof

NCIER® has delivered 1,118 ASIM and school safety classes, preparing 30,948 responders through 339,465 hours of training across all 50 states and U.S. territories. Our instructor team includes 45 veteran law enforcement, fire, and EMS subject matter experts with more than 20 years of experience, and our ASIM courses consistently earn high marks from participants for realism, clarity, and impact on real-world readiness.

State of New Jersey — Statewide Standard & Mandated Training

In 2025, New Jersey's Attorney General issued Directive 2025-2, establishing a statewide standard for active violent event response and requiring every law enforcement agency in the state to adopt standardized policies and training. The directive identifies the Active Shooter Incident Management course as the framework for multidisciplinary response and early integration of law enforcement, fire, and EMS. Counties such as Bergen are using ASIM Basic to meet the directive's training mandate, with specific deadlines requiring all agencies to have designated officers trained by mid-2026 and additional personnel trained by the end of 2026.

New Hampshire — Statewide ASIM Deployment

In New Hampshire, NCIER spent two weeks delivering four ASIM Basic Train-the-Trainer courses hosted by NH HSEM, training first responders from 54 agencies and minting new local ASIM trainers. Agencies walked away not just with trained individuals, but with an internal capability to keep running ASIM-based training and exercises long after the initial deliveries were complete.

The activities and instructors' stories/experiences were the most valuable pieces of this course. Their experience is so vast and varied that the entire public safety community is represented through the instructors, and they can all provide input from their own experiences.

Which part(s) of the course was LEAST valuable to you? Please explain why.

I think the players in the exercise should have been left to make their own mistakes more often. I understand and appreciate the prompts given by instructors at the boards, but I think there were too many times in which the responders looked like deer in the headlights, and instructors' prompts were the only thing getting them along. Let the incident suffer and have it come out in the hotwash.

Please provide any other comments or suggestions you have for improving this course.

This is one course that I feel needed an ICS review. I can't believe I'm actually saying that because I wish it was removed from almost every class. However, I think it was clear that some first responders in this course were in need of a review which would have made the first few activities run smoother.

What other training is most important to you now that you have completed this course?

I would like to get into all-hazard incident specific training courses and dive deeper into the positions explored in this training.
