Schools, especially grade schools, have become completely female dominated over the last 30 years.
Boy, haven't they. My DD's elementary school has no male teachers, administrators, or support staff. Most days, her bus driver is the only grown man (and the only adult who is obviously of color - some of the support staff are Native American, but a non-Native kid wouldn't necessarily recognize that) she has any contact with. One of the reasons I'm glad I have a girl - that situation isn't ideal for girls, but is worse IMHO for boys.
Middle school isn't much better. The principal and counselors are women, as are 33 of the 42 teachers. The men in the school are the assistant principal (normally the person who handles discipline issues, so you see him only when you're in trouble), 5 electives teachers (phys ed, 3 music, and shop), and 2 (out of 3 total) social studies teachers. That school has one adult of color, a female special ed teacher.


Our school started with that a while back but have apparently gotten away from it. 

But then he went on to explain about the build of confidence, etc. Karate was really a great thing for ds.
. And I have seen instances that this probably was the best answer!
