Little League Diamond Leader Training Program

Little League® offers numerous training opportunities to equip volunteers with the knowledge and skills needed to positively impact the youth of their community through the Little League program. This year, Little League® has come up with a new program called: Little League Diamond Leader Training Program. This program focuses on ensuring children have a positive, well-rounded experience on and off the field, this program is a FREE educational resource that provides coaches with an understanding of the impact that mental, social, and emotional well-being has in youth sports through detailed information, interactive scenarios, and a variety of additional resources.

As a condition of eligibility for selection as a tournament team manager/coach, the regular season manager/coach must have also completed the Little League Diamond Leader Training Program. This program must be completed prior to the individual being named a tournament team manager/coach and before participating in any practices or games. Tournament Team managers/coaches who have completed the program should be prepared to produce the Little League Diamond Leader completion certificate if requested by the District Administrator/Tournament Director.

We are encouraging ALL of our Managers and Coaches in District 33 to complete this course prior to tournament time.  Even though you are not planning on being eligible for a tournament team, the training is important for your development as a team Manager and Coach. We will be checking for Diamond Leader completion certificates at the beginning of the All-Star Season. Don't wait, take the course today. Here is the link to the Diamond Leader training course....

If you have any questions in regard to this required training, please ask your League President or me.
