Michigan’s Republican-led Senate has passed a measure that removes the 150-school cap on university-sponsored charters. The bill is now stalled in the House.
The way the current cap works: If a charter is considered "high performing," it is re-labeled a School of Excellence, and removed from the cap, which leaves a vacancy for a new university-sponsored charter school to fill.
One criticism of past charter studies is that the data is skewed because they compare apples to oranges; since charter school participation is voluntary, some worry the kids who sign up for charter schools have different characteristics than those who attend traditional schools.
