In today’s Wall Street Journal, Princess Lyles and Dan Clark, the executive director and lead organizer of the school-choice group Democracy Builders, argue that states and/or authorizers should require charter schools to “back-fill” their “empty seats” when they lose students to attrition. This is a terrible idea.
Their argument in favor of requiring charters to backfill is twofold. First, they say it’s unfair to compare schools that backfill to those that don’t, because those that don’t (like Eva Moskowitz’s Success Academies*) almost certainly end up with a more motivated, higher-performing population over time as weaker, less engaged students depart for less challenging environments. It’s especially unfair, they say, if the comparisons are made on proficiency rates—the percentage of students passing state tests—instead of individual student growth. (I agree that such comparisons are unfair. More on that below.)
Second, they argue that, by not backfilling seats, schools like Success Academy are limiting opportunity. As a result of this policy, parents only have a shot at getting their kids into schools at designated entry points (like kindergarten or sixth grade). If families lose the charter school lottery for those specific grades, they are out of luck forever.
It’s a reasonable point, and I respect schools like Democracy Prep that welcome in students at any grade when space opens up. But whether to do this should remain the prerogative of the school, not the state or its regulators.
Why? Because there are strong instructional arguments...
