Maybe local sports but not PIAA. It comes directly from Wolf COVID-19 Guidance for Sports
Pre-K to 12 School Sports
Pre-K to 12 (PK-12) school sports under the Pennsylvania Interscholastic Athletic Association (PIAA) and the Pennsylvania Independent Schools Athletic Association (PISAA) are permitted to resume in counties designated in the Yellow and Green phases, in alignment with the PDE Preliminary Guidance for Phased Reopening of Pre-K to 12 Schools and the CDC Considerations for Youth Sports. This also applies to amateur high school boxers under the authority of the State Athletic Commission (SAC).
The decision to resume sports-related activities, including conditioning, practices and games, is the discretion of a school entity’s governing body. Each school entity must develop and adopt an Athletics Health and Safety Plan aligning to the PDE Preliminary Guidance for Phased Reopening of Pre-K to 12 Schools prior to conducting sports-related activities with students. The plan must include the provisions of this guidance, be approved by the local governing body of the school entity, and be posted on the school entity’s publicly available website. The plan does not need to be submitted to DOH or PDE for approval.
Any sports-related activities in Yellow or Green phased counties must adhere to the gathering limitations set forth by the Governor’s Plan for Phased Reopening (25 in yellow, 250 outdoors and 25 indoors in green) and the facility as a whole may not exceed 50% of total occupancy otherwise permitted by law. During the Yellow and Green phases of reopening, sports-related activities at the PK-12 level are limited to student athletes, coaches, officials, and staff only. The addition of visitors and spectators will be contingent upon future health conditions within the state and local communities.
This guidance is preliminary; as more public health information is available, the administration may work with impacted entities to release further guidance which could impact fall, winter, or spring seasons.
