After a lot of research and a tremendous amount of experience running clinics - most sessions follow the model of small groups (broken up by age and skill level) rotating through stations for a majority of the time together.
This format allows the players to get a ton of touches on the ball, stay engaged throughout the session, avoid standing in lines, learn from various trained coaches instead of just one voice for the duration of the clinic and to perform a variety of skills/fundamentals essential to be successful on the lacrosse field. In short - the players are learning through constant repetition so they can take those learned skills with them into game situations.
Bethesda Lacrosse provides the following clinics throughout the year:
