Subclaims¶

q1 i? Prior research suggested KIPP schools have positive impacts on student achievement, but most studies included only a few KIPP schools or had methodological limitations. → Christina Clark Tuttle 2013

q1 · i? · causal · r?

The authors' characterization of the existing evidence base: prior studies "have included only a few KIPP schools or have had methodological limitations", motivating a larger, more rigorous national evaluation. This is the authors' summary judgment, not a tested result.

"Prior research has suggested that KIPP schools have positive impacts on student achievement, but most of the studies have included only a few KIPP schools or have had methodological limitations."

Discussion¶

Related Claims¶

• The national KIPP evaluation uses experimental and quasi-experimental methods to estimate effects of KIPP middle schools across the country — related
• KIPP charter schools have positive effects on mathematics achievement for middle and high school students — a narrower finding that bears on this claim
• A lottery-based randomized controlled trial of KIPP middle schools found statistically significant positive effects on state math and reading tests — a narrower finding that bears on this claim
• A lottery-based randomized experimental analysis confirms KIPP middle schools' positive impacts — a narrower finding that bears on this claim
• Methodological scope of existing research is limited: small samples, single courses, and short-term interventions — a broader claim this one bears on
• Prior charter school research shows mixed student achievement results, which the authors attribute to differing policy environments or methodological assumptions across studies
• KIPP middle schools' positive effects extend to enrollment in 4-year college programs, not only middle school achievement — related
