Each year, Little League® provides its constituent leagues with current Little League rules, regulations, and policies that outline and define the operation of the program. It is important for all Little League volunteers and parents to be familiar with the most up-to-date version of Little League’s Official Regulations, Playing Rules, and Operating Policies. These rulebooks, published for all divisions of Little League Baseball®, Little League Softball®, and the Little League Challenger Division® provide the structure and support for local leagues and Districts to provide a meaningful Little League experience for all children in their community.

Educational Resources
Little League® University (LLU) is the free online training and education resource for parents, managers and coaches, local league and district officials. Each of the articles, tips, drills, and videos available on LLU were developed with the Little League volunteer in mind. The intent is that these materials serve as a quick reference and can provide assistance and guidance to those operating the Little League program at the local and district levels.
