The number of charter school authorizers slightly decreased this year. Charter school growth continues to outpace authorizer growth by nearly three to one. There are now 6.7 schools per authorizer.
NUMBER OF CHARTER SCHOOL AUTHORIZERS OVER TIME
*Note: The decrease this year is due to a change in Arizona policy, the refinement of counting techniques in Georgia, and several Minnesota authorizers discontinuing their authorizing work.

Changing the number of authorizers in a state has no relationship with charter school growth.

*Note: This analysis does not include the outliers of California and Minnesota.
A decline in authorizers doesn’t necessarily mean a decline in the number of charter schools.
For example, states such as Arizona and Georgia lost authorizers but saw an increase in the number of charter schools in their states.
