When did the students limited to school facilities?

There's no single historical point when students became limited to school facilities. The extent to which students' activities were confined to school grounds has varied greatly across time, cultures, and specific schools. Factors influencing this include:

* Historical Period: In earlier eras, schools might have had less structured supervision, and students had more freedom to roam. Over time, safety concerns and a shift towards more structured learning environments led to increased limitations.

* School Policies: Individual schools establish their own rules regarding student movement and activities on and off campus. These policies evolve based on local circumstances, safety concerns, and legal considerations.

* Legal Considerations: Laws regarding truancy and student safety also influence how much freedom students have outside of school facilities.

In short, there's no specific date. The limitation of students to school facilities is a gradual process that continues to evolve.
