2.5
An individual who knows the basics, and a majority of the rules (but probably not all of them).  An individual in this range will sometimes also play midcourt or have trouble with the concept of “returning and running” and “serving and staying”.  Most often, third shot drops are not implemented, but if they are, they are high or missed.  A 2.5 level will also serve and return serve inconsistently.  This level can sustain a short rally with people of similar skill levels. 

3.0
This level is defined as someone who always “serves and stays” for the serve, and will also “return and run” on a return of serve.  A 3.0 also knows what a third shot drop is, but is not yet proficient in this skill.  This level also can sustain a small dink rally, but often pops the ball up.  This level generally lacks direction and intent. 

3.5
This level is defined as someone who always “serves and stays” for the serve, and will also “return and run” on a return of serve.  Consistently working on a third shot drop, but is not yet accurate.  This level also can sustain a small dink rally and gets a majority of their serves in.  This level of player is beginning to understand when it is safe to run to the kitchen line and can understand a hard shot vs. a soft shot.

4.0
Players can consistently hit both forehand and backhand shots with pace or without. Third shot drops are more consistent, but understands moving to the line safely when they are not.  Players know nearly all of the rules, and can sustain a long dink rally.  Players at this level begin to identify others’ weaknesses and attempt to exploit them.  At this level, strategy is implemented and are working on set-up shots.
