Authorizing Data in Depth: Closure, Renewal, Replication

NACSA collects data on two different types of closures: those that happen during a charter school’s renewal process (typically once every five years) and those that happen outside the renewal process (typically a charter revocation for persistently or egregiously low performance). The overall closure rate is the total number of closures in a given year as a proportion of all charter schools in an authorizer’s portfolio.
The overall closure rate has increased compared to 2010-11 and remained fairly stable since 2011-12.
While there are significant annual fluctuations, it appears that LEA and SEA authorizers have a slightly increasing closure-rate trend, while ICB authorizers appear fairly stable.
- LEA (5.0%), NEG (7.7%), and SEA (5.5%) authorizers had overall closure rates above the overall closure rate among all large authorizers (3.7%), while NFP (2.4%), ICB (2.5%), HEI (2.8%) authorizers reported having a slightly lower closure rate than the overall closure rate.
- Some authorizers had wide differences in the closure rates during and outside the renewal process—HEIs and ICBs, in particular—while others, such as SEA authorizers, reported a smaller difference.
