Regression on the same 711-student iReady dataset (Table 2): delayed start minutes showed an estimated effect of "-.07 SD in math" with p=.02, with model fit change described as negligible for the raw minutes metric in math outcomes.

"The results of the models are presented in Table 2, where each row is the output of a separately estimated regression. For delayed start, the esti- mated effect was -.07 SD in math and -.10 SD in ELA."
