The lack of “teacher equity” in education systems across the country — including the Clark County School District — is by design. School districts and teacher unions have long embraced contracts and policies that ensure a steady flow of exceptional, experienced teachers to stable, higher-achieveing, higher-income, less-violent campuses where parents are more involved. Meanwhile, lower-achieving, lower-income, more-violent schools with higher minority enrollment and less parental involvement serve as training grounds for the newly hired — and the last stops for poor teachers who should be fired.
