Aggression/Apprehension Control Test

The Aggression/Apprehension Control Test is a comprehensive evaluation of the Team’s control and courage under situations simulating on-duty encounters.

The Master Trainer/Trainer will check and approve all equipment prior to the test, as well as attempt to assess the capability of the Team and decoy. At any time the Master Trainer can terminate the test for equipment deficiency, decoy inexperience or any other cause deemed to be of significant safety concern to the handlers, by-standers or K-9s.

A bite suit, sleeve or hidden sleeve can be used by the decoy, per the Master Trainer’s instructions.

False Start/Call Out/Recall

K9 will be placed in a down or sit/stay stance. The decoy will proceed quickly away from the team; with no apprehension from the K9 (distance 50′-150′). The handler will then “send” the K9 and terminate (call out) the send at a distance of approximately one half of the total distance. The “send” can be terminated by a sit, down or a recall. There can be no contact between the decoy and the K9. The handler will bring the K9 to a heel position by either recalling the K9 to a heel, or proceed to the downed K9 and placing the K9 into a heel position.

Gunfire/Pat Down

The decoy will fire two (2) shots at a distance of 75′-150′. The K9 will be deployed for the apprehension, with a third (3rd) shot fired after the K9 leaves the handler. The K9 must make the apprehension to pass. The handler will then either call out the K9 and have the K9 return to the heel position, or down the K9 at a location of approximately 75′ from the decoy. The handler will approach the decoy and conduct a “pat down” search with NO apprehension made by the K9.

Master Trainers will have the authority to not grant a “pass” rating based on an excessively weak or poor bite. Failure to “call out” the K9 in a timely manner, or any unauthorized bite by the K9, will result in failure.

Handlers may use whatever “duty gear” on a K9 that is used, approved or mandated by his/her Department or Employer; with the approval of the Master Trainer. However, NO, “external stimulus” will be allowed during any phase of the Aggression Control Test.


Any urinating/defecating in training or testing area and/or around a “hide” is immediate grounds for failure!

The Aggression certification will remain in effect for one year as long as a good standing member with NAPCH and the Team remains intact.
