The RAND Corporation released a study of Chicago charter schools today. It's conclusions are three-fold:
Charter schools don't cream from the top - students
attending charter schools who previously attended traditional public schools
have similar histories of academic achievement as students who remain in
traditional public schools.
Charter schools don't create racial or ethnic
segregation, either in the charter schools themselves or in the public schools
that their students are leaving.
Charter schools do a better job at graduating high school
students. The
authors used a very interesting means of controlling for the backgrounds of
charter high schools students. They looked primarily at students who attended
charter schools in the eighth grade; some students went on to charter high
schools and others went on to traditional public schools.Those that went on to charter high schools
graduated at a higher rate, and did better on the ACT than the comparison
group.This was evident, primarily, in
charter schools that use a multi-level approach (K-12, 7-12, etc.).Charter schools that serve only grades 9-12
did not perform significantly better than traditional public schools.The weakness in this approach, of course, is
that the authors do not look at how charter schools have prepared students for
high school - they do not compare high school freshman who previously attended
charter schools to freshman who attended traditional schools.They also don't show how charter high schools
that serve only grades 9-12 compare to traditional public high schools in
overall performance.
However, buried in the analysis is that students who HAVE
NOT attended a charter school in eighth grade but go on to attend a charter
high school have a ten percent higher probability of graduating high school
than similar students who are enrolled in traditional public schools.
So, the primary conclusion about school performance from
this study is that charter school students are much better off remaining in
charter schools for high school than transferring (or being assigned to) a
traditional public school.A secondary
conclusion is that students who attend traditional public schools during middle
school are better off attending a charter high school.The policy implications from this are
two-fold:
- Chicago needs to open more charter high schools
- Chicago needs to allow charter elementary schools (who
are willing to do so) to expand their approach to high school.
