Teaching qualifications

[DHBirr]

The school's fight song begins with the stanza (and yes, the full song can be found on YouTube):

Maidens of St Trinian's, gird your armour on.
Grab the nearest weapon; never mind which one.
The battle's to the strongest; might is always right.
Trample on the weakest; glory in their plight.

I think Mary Stewart shouted the series out in one of her early books, with the heroine jokingly claiming she was an alumna.  At the very least, she explained her practicality by saying she'd survived a rather chaotic school where "they taught us a lot ... at the tough end of [school name]."
