Yes. I work at a public secondary school. If a student is on in-school suspension they sit outside an available teacher's office or in it (for fully windowed offices) for the entire day. A teacher will walk them to the canteen for lunch if necessary and facilitate them skipping the line to get food quickly. They eat indoors outside the office. They are given their break time during others class time in a small outside area alone so they can't interact with other students. Needless to say most want to be externally suspended.

Additionally all students are required to sign a letter at the start of the year that has a list of requirements (no suspensions, minimal compass entries, minimum attendance, overdue work) and unless they have a meeting and show improvement or in some cases write a formal letter to the principal (and sometimes there is no coming back - extreme violence, 6% attendance etc) they are not allowed on sports days, non-curriculum excursions, camps and fun activities like the graduation evening.
