That is not accountability, that is oppression. Accountability comes from relationships and responsibility. That's what small schools produce. You can't hide. It's a group of committed folks.
Accountability requires autonomy.
A big mistake is not giving small schools the autonomy that they need to do the work that they need to do. Small school teachers, and parents, and community members are willing to be held accountable. But the only way they can be held accountable is if you give them the autonomy to develop the curriculum, to organize their time, to figure out their assessment system and the ways that they would measure student progress. We could always close down small schools if they don't work. However, we don't close down big high schools when they don't work.
