3 Test Execution and Evaluation

3.1 General Regulations

Performance evaluations may only be done according to the criteria set forth by these 

test rules and are noted in grades and points. The grades and related points must reflect the 

execution of the exercise.

At events where rankings are given, the highest scores in the phase A (nose work) before B 

(OB./DEX.) are decisive
