Parent commitment is key. If you can have a strong parent involvement in the program year after year success will come. Recruiting in grades 9-12 can be a futile effort. If they have not wrestled in the past few will be interested. At this level peer pressure maybe the best way to get older students to come out. Developing a very large, strong, active, committed youth program will keep the kids out for years to come.
Best programs are the ones where kids have been on the mat for years (year round) and involved in wrestling outside of the school (year round) and parents are very much involved (year round).
k-12 host, host, host and host events (year round). Start young, get families involved and make it fun (year round).
