Subclaims¶

q2 i1 Students who started at Green Dot Public Schools in 2007–08 and 2008–09 had significantly higher attendance rates during the fourth year of high school than comparison students (effect size 0.27, p < .01, 662 students). → Green Dot Public Schools 2018 q2 i0 No statistically significant or substantively important effect on school attendance was found in Year 1 for students who started ninth grade in 2009–10 (Cohort 3; effect size 0.00, p = .89, 916 students), a null result rather than proof of no effect. → Green Dot Public Schools 2018 (2)

Evidence¶

Green Dot Public Schools 2018¶

Green Dot Public Schools. (2018). WWC Intervention Report: Green Dot Public Schools, Charter Schools. What Works Clearinghouse, U.S. Department of Education. https://ies.ed.gov/ncee/wwc/InterventionReport/686

q2 · i1 · small effect, g = 0.27 · causal · r2

The WWC review reports that in the Herman et al. (2012) quasi-experimental study (propensity-score matched; the WWC found the analytic groups equivalent at baseline and rated the study as meeting standards with reservations), Cohort 1 and Cohort 2 Green Dot students "had significantly higher rates of attendance during the fourth year of high school than comparison students." The Year 4 effect size is 0.27 (p < .01, 662 students in 11 schools). The domain rating is potentially positive effects.

"Students who started at Green Dot Public Schools in 2007–08 (Cohort 1) and 2008–09 (Cohort 2) had significantly higher rates of attendance during the fourth year of high school than comparison students."

Green Dot Public Schools 2018 (2)¶

Green Dot Public Schools. (2018). WWC Intervention Report: Green Dot Public Schools, Charter Schools. What Works Clearinghouse, U.S. Department of Education. https://ies.ed.gov/ncee/wwc/InterventionReport/686

q2 · i0 · negligible effect, g = 0.00 · causal · r2

The same reviewed study found, and the WWC confirmed, "no statistically significant or substantively important effects" on Year 1 attendance for Cohort 3. The effect size was 0.00 (p = .89, 916 students in 11 schools): a nonsignificant result, not a demonstration of no effect, since equivalence of outcomes was not tested. The WWC did find the analytic groups equivalent at baseline. This null result qualifies the attendance domain finding.

"The authors report, and the WWC confirmed, no statistically significant or substantively important effects of Green Dot Public Schools on school attendance in Year 1 among students who started ninth grade in 2009–10 (Cohort 3)."
