It is all over the place. Some districts are great, some are terrible. There is a theoretical framework of accountability at the County and State level, but it is not enforced hardly at all.

So it is up to local school boards and superintendents, and the local municipal tax levy. Most medium and small districts’ BOE members are regular citizens who are elected with no qualifications at all, and lean on the Superintendent for everything. So if you get a bad one (and it is common), your district is screwed for many years.
