If you’ve never had a kid at Groton I don’t think you can not comprehend how much the school keeps parents at arms length. They could easily have set up a system to give feedback in a reasonable way. Instead it’s directed straight to the headmaster, who then says straight up he doesn’t care. Usually I agree with you @cinnamon1212 but in this case you’re off base. I’ve heard the warm way you talk about Hotchkiss, that is missing in Groton’s relationship with all the parents I know personally.
And in the end, there should be an appropriate way for kids and parents to have their concerns heard by a school. At Groton that does not exist. Sure there may be crazy parents whose feedback is ridiculous, there may also be parents who have very valid concerns and good ideas.
