Beginner training plan
Your first trainingI would begin with the basics as far as positioning of arms, side to side movements, diving, bow and arrow technique, how to hit the ball, serving. 
Training 2-3We would build on those same skills, and if comfortable introduce some live play as well as some quicker pace functional drills.
Training 4-10There would be a rise difficulty of the balls they are digging, the type of serves I would be introducing, and the all-around play aspect would be honed it.
Training 11+To be challenged at what they are comfortable at, and what they are not in order to build confidence in their skills. We would target what was most important for them and slowly work up to the lesser needed skills. It would all be a plan worked out with the client and parent if needed.
