…The achievement gap between poor Black and Latino students in cities and rich white students in suburbs represents a sickening waste of human ability and is a rebuke to the American credo of equal opportunity. Its stubborn persistence has tormented generations of educators and social reformers.

For many education specialists, the left’s near abandonment of charter schools has been a bleak spectacle of unlearning — the equivalent of Lincoln promising to rip out municipal water systems or Eisenhower pledging to ban the polio vaccine. Just as the dream is becoming real, the party that helped bring it to life is on the verge of snuffing it out.

But it wasn’t until I met my wife that I got interested in charter schools. Robin has devoted her career to education policy: She studied it in graduate school, taught at a low-income school, worked in local and federal education departments, researched for a liberal think tank, did executive-level work for a charter-school network.
