Subclaims¶

q3 i? In NAEP difference-in-differences estimates, a binding state mandate increases math achievement by 2.2 points (7.7 percent of a standard deviation) and reading achievement by 2.0 points (5.4 percent of a standard deviation). → Frisvold David E 2015

q3 · i? · causal · r2

Difference-in-differences analysis of the 2003 4th-grade NAEP math and reading samples (53,430 math; 51,640 reading), comparing schools above and below state FRP thresholds across states with differing thresholds. The study reports "a binding state mandate increases math achievement by 2.2 points" and reading by 2.0 points; no standardised effect size (d, g, r) is printed, so no magnitude beyond the printed points and percent-of-SD figures is claimed.

"a binding state mandate increases math achievement by 2.2 points (with a standard error of 0.902), which is 7.7 percent of a standard deviation and 0.9 percent of the mean, and reading achievement by 2.0 points (with a standard error of 1.124), which is 5.4 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
• 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
• In NAEP regression discontinuity estimates, exceeding the state threshold increases math achievement by 2.6 points (9.1% of a standard deviation) and reading achievement by 4.4 points (12.2% of a standard deviation) — 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
