For Mathematics the effect of the SWH approach is associated with a statistically significant 2.06 point increase per year, with effect size of 0.14.This represents a 12.01% greater annual increase for the treatment group compared to the control group in Mathematics. The number of observations in the model for Mathematics includes 28,372 measures, for 15,388 students, across 48 randomization units.

For Reading Comprehension the effect of the SWH approach is associated with a statistically significant 1.53 point increase per year, with effect size of 0.09. This represents a 9.68% greater annual increase for the treatment group compared to the control group in Reading Comprehension. The number of observations in the model for Reading Comprehension includes 28,389 measures, for 15,351 students, across 48 randomization units.
