NIJ Level IIIA vs. Level III: Understanding Ballistic Protection Ratings
Posted by Kate Murphy on Aug 20th 2026
Ballistic protection has its own vocabulary, and a few letters can make a meaningful difference. Level IIIA and Level III may look nearly identical on the page, but they describe two distinct threat categories: Level IIIA is associated with handgun threats, while Level III is associated with a specified rifle threat.
Understanding this difference can help you better compare ballistic-resistant products and choose the level of protection that fits your organization’s needs.
What Are NIJ Ballistic Levels?
The National Institute of Justice, or NIJ, created a rating system that helps explain what types of ammunition ballistic materials are designed to resist. Each level represents a different type of protection.
For the products discussed here, the difference is straightforward:
- Level IIIA is designed for certain handgun threats
- Level III is designed for certain rifle threats
These ratings make it easier to compare ballistic-resistant products. However, no single rating covers every type of ammunition, so it is important to check the rating and testing information for the specific product you are considering.
When a partition or mobile whiteboard is labeled Level IIIA or Level III, the rating explains the type of ballistic protection built into the product. It does not mean the entire product is certified by the NIJ.
Level IIIA: Handgun-Rated Protection
Level IIIA is designed to resist certain powerful handgun rounds, including .357 Magnum, .44 Magnum, and 9mm ammunition—all of which were included in product testing.
The easiest way to remember it: Level IIIA is for handgun threats, not rifle threats. Rifle threats require a rifle-rated solution.
Level III: Rifle-Rated Protection
Level III is designed to resist certain rifle rounds, including the 7.62 x 51 mm round used during Level III testing. Because rifle rounds typically strike with more force than handgun rounds, Level III provides a higher level of ballistic protection than Level IIIA.
How Versare Integrates Ballistic Protection
Versare offers ballistic-resistant products that also serve a practical purpose in the room. Depending on the product, organizations can add protective coverage with a movable partition or a mobile whiteboard.
Products available with Level IIIA handgun-rated protection include:
Product with Level III rifle-rated protection:
Because some models may look similar, always check the product’s specifications to confirm whether it provides Level IIIA or Level III protection.
Why Add Ballistic Protection to a Whiteboard or Partition?
These products provide protection while remaining useful for everyday activities. A mobile whiteboard can support meetings, lessons, and presentations, while a portable partition can divide a room, guide foot traffic, or add privacy.
They can also support emergency plans based on the FBI’s Run, Hide, Fight guidance. If running to safety is not possible, a ballistic-resistant whiteboard or partition may help create a more protected area where people can hide.
Because the protection is built into a familiar room feature, the product blends naturally into the space. Organizations gain an added layer of preparedness without making the environment feel unwelcoming or overly focused on security.
How to Choose Between Level IIIA and Level III
The right rating depends on your facility and its safety needs. A qualified safety or security professional can help you determine which level of protection is most appropriate.
Before choosing a product, consider:
- Whether you need handgun-rated or rifle-rated protection
- Where the product will be placed
- How much coverage the space requires
- How the product will be moved or stored
- Who will be responsible for using it
- How it will fit into your existing safety plan
Versare’s team can also help you compare product sizes, configurations, ratings, and testing information.
Find the Right Protection for Your Space
The difference between these ratings is easier to remember than it may first appear: Level IIIA is designed for certain handgun threats, while Level III is designed for certain rifle threats.
Versare incorporates these levels of protection into mobile partitions and whiteboards that remain useful in everyday spaces. They can support meetings, presentations, room division, and other daily activities while adding another layer to an organization’s safety plan.
