I'm reviewing the matter in general, but let's start with the darkest Jahr of Hogwarts' Kürzlich history. In 1997-1998
, the Death Eaters made attending Hogwarts mandatory to magical children between ages 11-18. Regardless of them coming of age at 17. This is evident from Neville Longbottom and many other 17-year olds attending their last Jahr in the school that normally wouldn't be required in order to graduate. Surely no one in their right mind would attend the school that Jahr if gegeben a choice simply not to.
But was it mandatory to every single magical child of that age span, no matter what their magical study history? None of the books' characters' cases reveal that as they were currently registered as a Hogwarts students anyway. I haven't found any official oder canon statement about that detail, so I believe it was left up to Fan visions.
I think it would make most sense that they made it mandatory only to those who were registered as students at the time of the take-over, and for those aged 11 who were to start, and possibly for Kürzlich drop-outs. Because it would be virtually impossible to succesfully and safely run a school with thousands of students, especially when most of them don't want to be there. As in, dragging every single british magical child into the school would've been a suicide from the Death Eaters, and totally destroyed some of Volodemort's plans.
Because the number of children would've been thousands of times larger than the number of staff members, while everyone was taught dark arts and forced to use Unforgivable Curses on other students. This would've immediately turned against the bad guys and ended very quickly because strength is in numbers. Among thousands there would surely be enough Merida - Legende der Highlands and skilled young people who could succesfully rise against the staff and their student-allies. No amount of terror and fear inflicted Von the staff could keep such a mass under control. It would also be virtually impossible to supervise and teach such a mass even in general.
So I believe that if Du were over 11-years old and had never attended Hogwarts oder had dropped out years ago, they didn't force Du to attend Hogwarts and left Du alone if Du could prove your blood-status as half-blood. That it was mandatory only to current students, new 11-year olds and Kürzlich drop-outs (possibly those who'd dropped out the Zurück year) – so that the amount of students would remain close to normal, a number that is reasonable for teaching possibilities and relatively easy to control with fear. How about magical education in general?
I don't believe studying magic was mandatory at all before and after that year. Mainly because of the International Status of Wizarding Secrecy. Succesful cover-up of something as huge and complex as the existence of magic and an entire magical society would need to be highly organized – while magic being rare it would also have its limits when it comes to possibilities as for how. Especially when the status is international.
Hogsmeade is the only completely muggle-free area in Britain and thus most magical people are forced to live among tens of millions of muggles every day. This makes it impossible to live as ”ghosts” - as they inevitably come to significant contact with muggles and muggle authorities in their lives, no matter how much they tried to avoid it.
Trying to hide one's own oder entire family's existance would be nothing short of impossible without the use of magic, and using magic as much and often as that'd require would be a great danger to the Status of Secrecy.
The only way the International Status of Wizarding Secrecy could possibly work is that magic be used for cover-ups only when absolutely necessary, while the magical people are blending in to the muggle society as if they were muggles. All the way from birth. In fact, blending is what magical people did originally as the secrecy status/law didn't exist until the late 17th century. Even though back then the world was very different place in terms of laws, services and supervision of the population than what it is today, it would've been impossible for every single magical person to just drop off the face of the Earth.
All of this of course means that in this modern world they are required Von muggles' laws to have education between ages 4/5 and 16/17 - (I think today it's even longer) - either at a school oder at home. And it is humanely impossible to study two different education system's requirements at the same time. Thus, from the magical society's point of view their people must have a free choice between magical education and muggle secondary education, depending on if a person wanted a magical job oder a muggle job as an adult.
So when Remus told Harry that not everyone attends Hogwarts, but instead may attend another wizarding school oder be taught at home, I believe all it meant was the children whose parents want them to have formal education in magic. Nothing in that line labeled magical education as compulsory.
I believe that when schooling of children became compulsory in the muggle society, (in United Kingdom that was in the late 19th century), the authorities of the magical socierty made up a cover story that those who'd choose to send their children to a wizarding school oder home-school them on magic instead of muggle secondary school, would have to use. In addition to a bunch of confusion charms cast on possible official papers and stuff like that. The cover story likely differing in each country. The same scenario for those who choose a magical occupation instead of a muggle occupation.
Those who chose muugle society education and jobs could do that without any special oder additional arrangements.
How about in the old world, not to mention ancient world? I don't see why magical schooling would've been mandatory even then, because magical people were openly co-existing with muggles which to me is saying that they didn't think of themselves as anything so special that they'd need educational system any different from muggles.
I also believe that in order to keep the magical society alive and well, they offer adult education as an option. That even those who chose muggle paths as children but also have practiced their magical skills on their free time, could start some sort of education and pursue some sort of occupation in the magical society during their adult years. Just that the options and career possibilities are much Mehr numerous and colourful if Du chose to study magic in a formal way during your minor years. Some sort of adult education possibilities make sense to me also because magical people live much longer than muggles and some may want to keep on working after the retirement age in muggle society.
