* Location: Rural schools likely had different schedules than urban schools. Different states and even different districts within a state would have their own practices.
* School level: Elementary schools, middle schools (if they existed in that area – junior high was more common then), and high schools all had different schedules.
* Specific school policies: Individual schools had autonomy in setting their schedules.
While we can't pinpoint a specific time, it's safe to say that most schools in 1930 likely started between 8:00 AM and 9:00 AM, with some potentially starting earlier or later. Afternoon dismissal times would have reflected this, with a likely lunch break somewhere in the middle of the school day.
