Study 3 used a comparative regression discontinuity design exploiting the kindergarten entrance birth-date cut-off, with outcomes of grades 3 to 5 English/Language Arts and Math MCAS scores and proficiency levels. The article reports Cohen's effect sizes of approximately .20 to .28 and proficiency likelihood increases of approximately 37% to 43%.

"Positive City Connects effects were found in both 3rd and 5th grade math and reading scores. Cohen’s effect sizes for analyses using MCAS raw scores as outcomes ranged from approximately .20 to .28. Increases in the likelihood of achievement at the proficient level or higher ranged from approximately 37% to 43%."
