* Data Collection Challenges: Tracking this information across all schools globally is a massive undertaking. Data collection methods vary widely across countries and even within them.
* Varied Educational Systems: Educational systems and curriculum requirements differ significantly between countries, states/provinces, and even individual school districts. Some mandate daily PE, others have it a few times a week, and some have limited or no PE at all.
* Definition of "Physical Education": The definition and content of PE programs vary. Some schools might offer daily movement breaks but not structured PE classes.
While some countries or regions may have data on the frequency of PE in their schools, a global, accurate count is simply not available.
