theprof1 – cute reasoning but not entirely correct (not entirely false either)
For example: Yavne Teachers Seminary (shout out!) granted that is meant to churn out some teachers, so you wont find any Home Economics there (or any form of fun for that matter)
BY Intensive – Is also a place to go to become a teacher. Home Economics? Prolly not.
BYA (E”Y), BJJ, Bnos Chava, Hadar…. They dont claim to perfect the craft of teaching. It is 13th grade (for 20K a pop). If you can spend a 1/3 of the year on Tiyulim certainly they can spend some time teaching the girl how to cook.
