Several school choice studies have found null or modest effects on test scores only to turn up impacts on longer - term outcomes like graduation.
They looked at a bunch
of school choices studies and tried to see if a school's impact on student test scores was connected to its impact on student life outcomes.
A more recent summary, by Epple, Romano, and Urquiola, selectively included only 48 % of the empirical
private school choice studies available in the research literature.
I'm basing that conclusion of the weak connection on my review of those 7 charter and private
school choice studies as well as the Heckman book I referenced.
I show in the Harvard Conference paper that, contrary to Mike's claims, the connection between achievement and attainment findings actually is stronger in the Career / Technical Education studies than in the
average school choice study.
Editorials and op - eds cited «negative»
school choice studies twice as often as they did «positive» studies, with 36 mentions of «negative» studies compared to just 18 of «positive» studies.
As a result of our findings of no consistent statistical association between the achievement and attainment effects
in school choice studies we urged commentators and policymakers «to be more humble» in judging school choice programs or schools of choice based solely or primarily on initial test score effects.
He pointed to additional findings from
the school choice studies that could guide policy makers:
Selection bias — the problem that plagues
all school choice studies To investigate the effect that school choice has on student outcomes, researchers leverage statistical tools to try to make the most accurate comparison.
