Spencer Campbell spends much of his days walking the halls of Elk Ridge Middle School, checking breezeways for kids playing hooky, redirecting foot traffic between classes and checking on substitute teachers.
Campbell is one of two assistant principals at Elk Ridge, a school just south of Salt Lake City, Utah. It's his first year in the role and he looks the part. He's in his late 30s, sharply dressed, walks briskly and carries a walkie-talkie on his belt.
Before coming to education, Campbell owned a small business. He says he felt drawn to schools, though, so he got a master's degree and spent five years in the classroom as a teacher.
