The California Department of Public Health on December 14th, 2020 issued guidelines for youth sports (pdf). Based on the information contained in the guidelines, California aims to reassess the return-to-competition by January 4th, with January 25th, as the earliest possible start date for inter-team competition. In addition to these key dates, the guidelines also cover a range of topics to assist in future planning, including Sports Risk Profiles that classify different sports by their level of contact and transmission risk, and a new four-tiered system to identify sports by the level of contact and risk.
