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.



  • After a jump in the closure rate during renewal from 2010-11 to 2011-12, that rate has declined substantially.



  • The closure rate outside renewal has fluctuated during the last five years, but has increased substantially since 2010.


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.



  • The proportion of large authorizers reporting having a closure decision appealed has been relatively low but appears to be trending upward (19% in 2013-14 vs. 30% in 2014-15).
