Concussion Protocol: (Required Once)

1. (a) California law requires that all volunteers, including managers/coaches, administrators and officials must complete an online concussion training at least once before supervising youth athletes; a certificate from a prior season is valid for this season. It takes only about 30 minutes to complete the training.


2. A concussion and head injury information sheet must be signed by both the athlete and a parent/guardian before the athlete initiates practice or competition. An existing form from the 2020 spring may be used if it’s available. The signed sheet must be carried with the player’s medical release and code of conduct form.

Sudden Cardiac Arrest Prevention Protocol: (Required Once)

AB379 now requires the same protocols used for concussions in youth and high school sports to be used to help protect young athletes participating in school and community youth sports organizations from sudden cardiac arrest—the #1 killer of young athletes. Community youth sports organizations include an organization, business, nonprofit entity, or a local governmental agency that sponsors or conducts amateur sports competitions, training, camps, or clubs in which persons 17 years of age or younger participate.

2023 District-Wide Board Meeting Recap

I would like to thank all the Little League board members who attended our District 33 Wide Board Meeting on November 16th, 2023.  

We had 90 attendees and all leagues from the District were represented.

Hopefully, you came away from the meeting with some more insight of your role as a Little League board member.

All the breakout sessions groups were engaged, interested, excellent questions and very good participation from the veteran board members as well as new board members bringing in new ideas.

Congratulations to Tierrasanta Little League for having the highest percentage of their board members in attendance. As an appreciation, each board member from TLL will receive a gift card from Starbucks.

Thank you for being a volunteer,
