Qualifying scores
The goal of every competitor is to earn what is called a “qualifying score”. These scores count towards certain titles. As long as a run is under the SCT and free of faults, it is a qualifying run (also called a “Q”). In higher levels of agility competitions you need several Qs. In AKC agility for example, QQs are required to reach the level of Master Agility Champion.
In USDAA handlers need so-called “Super Qs”.
In the lower level, it usually takes three qualifying runs to earn a title (such as the Novice Jumpers Title). In higher levels, you might need dozens of single or double Qs.
Score sheets and displays
In local trials, score sheets are printed and posted after a class has finished running. The first placements in each class get a special ribbon (such as a blue ribbon for first place).
In larger competitions, the scores might be displayed on screens in real time.
Generally, you do not have to strive to win a class by being the fastest, Consistency and accuracy go a long way. A dog with medium speed but great accuracy will do very well in competitions and earn a lot of qualifying scores and titles.
