A defining feature of charter schools is the oversight structure provided by the authorizer. It is an authorizer’s job to determine whether schools are fulfilling the terms of their charters across numerous areas, not least of which is student outcomes. Contract renewal time is when those determinations matter most. Has a school earned the right to continue operating and for how long? While the typical charter renewal term is five years, most states give authorizers the discretion to offer longer or shorter terms if circumstances warrant. A new report looks at renewal term length decisions in four of those states, aiming to see how authorizers use that discretion and what impacts they associate with different term lengths.
The National Association of Charter School Authorizers (NACSA) surveyed 39 authorizers across Colorado, Florida, Indiana, and Michigan, all of whom had at least five charter schools in their portfolios. The survey asked respondents about all the renewal term lengths they grant and the reasons for granting different lengths. Twenty-six of those authorizers also agreed to participate in focus groups which delved into more depth on their survey responses and added an additional dimension: What effects—intended and unobserved—do authorizers associate with different term lengths.
Across all four states, five years was the most common renewal length. Respondents said that a five-year term provides them with enough data to make sound decisions and provides schools sufficient time to achieve any needed operational stability required by authorizers.
Longer-term renewals (anything more than five years) were rare, respondents said—typically reserved for schools with sustained strong performance across academics, finances, and governance. But they do have their upsides when granted, including reduced administrative burden for both authorizers and school staff, as well as incentivizing more favorable facility financing opportunities for schools with longer-term charters. On the downside, however, respondents reported that some schools declined in performance after receiving long-term renewals, with fewer intervention tools then available to authorizers.
Shorter-term renewals (anything less than five years) were most commonly reported in response to academic underperformance, financial distress, or governance problems. Authorizers intend them as leverage—a way to force change with new contract/accountability requirements or to signal that a school’s continued operation is conditional upon specific improvements. However, respondents provided little evidence that short-term renewals actually improved school performance. Repeated short-term renewals, respondents said, could also accelerate staff turnover, hasten enrollment declines, and do reputational harm to schools.
Interestingly, while five-year terms continue to function as the sector default and are deemed appropriate for most schools that are meeting expectations, they still generated concerns from some respondents. Having all or even most schools in a portfolio on similar terms creates clusters of renewals every year, resulting in a significant and ongoing administrative burden for authorizers that staggered/non-standard terms could alleviate. Additionally, any states that don’t allow shorter renewal terms lump both adequate and problematic charter schools into the same category; and any states that don’t allow longer renewal terms lump both adequate and exceptional schools together. Both situations, authorizers say, remove the quality signals that varying term lengths are meant to convey.
While these findings come from a limited, nonrepresentative sample of authorizers—those willing to speak on the subject—NACSA’s recommendations on renewal term length nonetheless reflect much of the insight they provide. To wit: The length of charter renewal terms should be determined through a deliberate, performance-based process, and not by default or tradition.
Long-term renewals should be reserved for schools demonstrating sustained excellence across all performance areas, and their contracts should include robust monitoring systems to detect declines in performance as well as actionable accountability structures if a decline occurs mid-cycle. Short-term renewals should be used sparingly—with “clear conditions and consequences”—and never as cover to kick painful closure decisions down the road a year or two. Finally, the report encourages charter supporters to band together to support state policies (or support implementation of new policies if they don’t already exist) that minimize “authorizer shopping,” the process whereby schools can easily switch authorizers if they don’t like, for example, the term length being offered.
