Much more difficult to convince parents that there is no inherent institutional health and safety problem when the whole school may at any moment be flooded out, trapped in a shed by an snow/heavy fog/inadequate foresight by mistresses, felled by a flying bookend, or married off to a passing member of the medical profession.

This seems to be one part of the school story that JK Rowling got absolutely right (except marrying off to doctors - but she does share a similar belief that almost everyone should be coupled up very shortly after leaving school).
Why yes, of course we have a Giant Squid/illegal dragon/dangerous Hippogryff/Whomping Willow/bit of Voldemort's Soul/hiding staircases/regular incidents of near death at school! But none of the parents worry because, very cunningly, we don't tell them. I would like to see Dumbledore in a twinkly eye-a-thon with Miss Annersley, though. (She might win with her magic voice that never needs to be raised to be heard over a crowd of chattering girls)
