KIPP public charter school network multi-grade-level impact evaluation¶

Element · All elements
Evidence · 8 claims (8 for) · 4 studies (4 causal), q2–q3 · 0 of 4 report an effect size · 5 claims rest on one study

Description¶

The article describes "the first high-quality study to rigorously examine the impacts of the network of KIPP public charter schools at all elementary and secondary grade levels," conducted by Mathematica as part of the associated project "KIPP: Preparing Youth for College" with a 2007-2017 time frame, prepared for Arnold Ventures. The evaluation compares achievement outcomes for KIPP students across elementary, middle, and high school levels, distinguishing new entrants from continuing students at the high school level.

Design Implications¶

Context¶

Requirements¶

• Rigorous examination of impacts across all elementary and secondary grade levels of the KIPP network

Constraints¶

• The brief reports average impacts; findings for continuing KIPP high school students do not extend to new entrants, and vice versa

Target Learners¶

• K-12 students in KIPP public charter schools

Target Learning Goals¶

• Reading and mathematics skills
• Science and social studies achievement
• College preparation and college application

Claims¶

• KIPP elementary schools have positive, statistically significant, and educationally meaningful impacts on three of four measures of reading and mathematics skills [+M]
• For students continuing from KIPP middle schools to KIPP high schools, achievement impacts are not statistically significant [+M]
• For continuing KIPP students, KIPP high schools have positive impacts on college preparation activities and the likelihood of applying to college [+M]
• KIPP high schools have positive, statistically significant, and educationally meaningful achievement impacts for students new to the KIPP network [+M]
• Average KIPP middle school impacts were positive and statistically significant throughout the 10-year study period, though higher in earlier years than recent years [+M]
• KIPP middle schools have positive, statistically significant, and educationally meaningful impacts on student achievement in math, reading, science, and social studies [+M]
• KIPP Pre-K may provide an additional benefit for reading achievement above and beyond KIPP elementary school [+W]
• KIPP Pre-K combined with KIPP early elementary school has positive, statistically significant impacts on reading and math achievement after five years [+W]

Related Elements¶

• KIPP (Knowledge Is Power Program) charter middle school network
• KIPP Pre-K program
• KIPP middle schools as an evaluated intervention across the country
• KIPP leadership development investment for network scale-up
• Longitudinal student-level dataset on entry, exit, attrition, and replacement in KIPP middle schools
