S24 is a day student at a boarding school that currently has a 60/40, day/boarder ratio. There are no Saturday classes, and if there were, I would have likely pulled him out after his 9th grade 20-21 school year. Our district does bus him everyday to and from school, which was a selling point on attending. We live just over 30 minutes away, so getting him to and from school every Saturday would have been a non starter.
The day / boarder ratio has hovered around 50/50 for well over a decade. It severely eroded due to Covid due to the schools previous reliance on Chinese students. With such a high percentage of day students, the school would have issues maintaining a mandatory Saturday schedule. Many day students come from a distance and parents would not be willing to make that sacrifice every week.
Some sports do have Saturday games, although many competitions are during the week. My son plays a sport that only has weekday matches due to availability of the facility, so he’s rarely on campus during the weekend. If kids are involved in theatre or robotics as they’re after school activity, there are no Saturday meeting times.
So for my son and the 60% day student population, attending his school is pretty close to attending a regular private or public day school. It does have an impact on boarder / day relations, although that doesn’t bother my son at all. He didn’t want to attend school as a boarder, so he’s happy with his school.
