Great with kids and great with adults are two entirely different constructs. “I don’t know why everyone is so crazy about Beth as a principal. She wasn’t that good in the classroom.” The teachers who say this don’t grasp that relating to adults is a different skill set.
A data point urban teachers unions don’t want you to know: in middle class and suburban school settings, a kid can academically survive two consecutive bad teachers. Not so with poor urban kids; two consecutive bad teachers takes them right out. I deal with a teachers union that will spend a quarter million dollars to defend a member they wouldn’t have their own kids in front of. That’s about power; it sure as Hell isn’t about the kids. But I digress.
