As charter school authorizers and states have increased performance expectations and grown less hesitant to close failing schools, "authorizer shopping" has emerged as a growing threat to overall charter school quality. Authorizer shopping happens when a charter school chooses or changes its authorizer specifically to avoid accountability. A low-performing school may shop for a new authorizer to avoid closure, or reopen under a new authorizer after closure. This report considers five examples of authorizer shopping in action and provides specific guidance to authorizers, policymakers, and advocates to address authorizer shopping. The following are appended: (1) Example 1: "Recycling--When Is a New School Really New?"; (2) Example 2: "Shopping or Finding the Best Fit?"; (3) Example 3: "Authorizer Shopping in a Virtual World"; (4) Example 4: "Unintended Consequences of Increased Accountability"; (5) Example 5: "Many Authorizers, Little Consistency"; and (6) Appendix Endnotes.
