Subclaims¶

q3 i? A fuzzy regression discontinuity design on NAEP data finds exceeding the state threshold raises math achievement by 2.6 points (9.1 percent of a standard deviation) and reading achievement by 4.4 points (12.2 percent of a standard deviation). → Frisvold David E 2015

q3 · i? · causal · r2

Fuzzy RD using local linear regression with a triangle kernel and bandwidth of 5 (optimal per Imbens and Kalyanaraman), comparing schools just above and just below state FRP thresholds in the 2003 NAEP sample. The study reports "exceeding the state threshold increases math achievement by 2.6 points" and reading by 4.4 points; no standardised effect size (d, g, r) is printed, so impact is null.

"exceeding the state threshold increases math achievement by 2.6 points (with a standard error of 1.242) or 9.1 percent of a standard deviation and reading achievement by 4.4 points (with a standard error of 1.820) or 12.2 percent of a standard deviation"

Discussion¶

Related Claims¶

• A binding state mandate makes schools 33 percentage points more likely to offer the SBP, and SBP availability increases math, reading, and science achievement in ECLS-K data — related
• Falsification tests show a binding SBP mandate is unrelated to achievement upon school entry, Title I funding, principal experience, and vigorous exercise frequency — reports the opposite
• The effect of a binding SBP mandate is larger for low-income students, males, and students from larger families, and does not vary with threshold levels from 10 to 40 percent — a narrower finding that bears on this claim
• A binding state SBP mandate increases 4th-grade math achievement by 2.2 points (7.7% of a standard deviation) and reading by 2.0 points (5.4% of a standard deviation) in NAEP difference-in-differences estimates — related
• Each year of attending a school with a binding SBP mandate increases math achievement by 0.572 points (2.7% of a standard deviation), reading by 0.470 points (2.0%), and science by 0.130 points (0.9%) — related
• Statewide, One-Star designation has a modest significant positive effect on ELA but not on math scores — related
• A binding SBP mandate increases milk and fruit consumption and decreases soda consumption, but its effects on attendance are imprecise, suggesting the achievement effect operates through improved nutrition — related
