  • We are extremely excited to have world-class investor KKR as our long-term value-added partner.

  • One possibility that's already being tried by a number of school systems, including the one in nearby Decatur, Ga.: so-called value-added tests, which gauge a student's progress over the course of a school year rather than merely determining whether the student is performing at grade level.

    When Teachers Cheat—And Then Blame the Tests

  • The controversy centers largely on using a statistical tool called "value-added" to evaluate teachers. Chronicle

  • And to do that, he is cleverly signing up so-called value-added resellers VARs. News

    Poll on NCLB: Americans want overhaul (but does Congress?)

  • In addition, the teachers laid off based on seniority have lower average value-added scores than those laid off based on those value-added scores as would inevitably be the case.

  • This suggests an obvious point, but always an important one: The idea of "quality-based" layoffs sounds great in an editorial, but, in practice, measuring "quality" is tenuous even when you predefine it e.g., in terms of value-added.
