A 2011 analysis of 213 S.E.L. programs involving 270,034 kindergarten through high school students published in the journal Child Development found that the participants demonstrated significantly improved social and emotional skills, attitudes and behavior compared with a control group, as well as an 11-point11-point academic achievement percentiles.
"Percentiles on a growth chart are very different from percentiles in academic achievement, but almost all parents want their children to be above the 50th percentile on the growth chart".
Schools began emphasizing social-emotional learning around 2011, after an analysis of 213 school-based programs teaching such skills found that they improved academic achievement by 11 percentile points.
A meta-analysis of 213 programs found that social and emotional learning interventions increased students' academic performance by 11 percentile points, compared with students who did not participate in SEL programs (Durlak et al. 2011).
Ballinger said that research shows that children who score below the 50th percentile on academic tests "have trouble with retention over a long summer vacation period". By cutting down on that vacation, the year-round school benefits these students in particular, Ballinger said.
And when you reach high school and the competitive pressure of being at the top percentiles of academic achievement, intramural participation and community service all converge.
The gap between the highest and lowest graduation rates across campuses for students at the 10th percentile of the academic index was 15.8 percentage points.
For students at the 75th percentile of the academic index, the gap between the highest and lowest graduation rates was a third of the size at 5.2 percentage points.
Rural students had lower academic entry scores and UMAT percentile scores but interview scores were not significantly different.
Table 6 ranks the campuses from highest to lowest predicted graduation probabilities for different percentiles of the academic index holding fixed the remaining characteristics (family income, the Dale and Krueger measures, etc).
Of course, he knows his percentile rank for predicted academic achievement, too.
