I’ve never particularly understood this criticism, at least for my school. Elementary school was a little like that because we had the one main teacher, but by middle school and high school we were being encouraged to try out different things. And that was just before magnet schools were a thing in my school district. Now my elementary school shares space with a Spanish immersion school and my high school has a special arts magnet program. It seems like kids are being encouraged more than ever before to explore their individuality.
