18 Trends in Chicago’s Schools across Three Eras of Reform
Other research at CCSR has documented the uneven-
ness in school improvement under decentralization;
during decentralization the schools serving students
from the most economically disadvantaged commu-
nities were least likely to improve, while the schools
serving more advantaged communities were most
likely to improve.

These outcomes can be explained
by differences in the social resources available in
school communities. Because decentralization placed
power in the hands of elected Local School Councils,
it is not surprising that communities where residents
were active in local organizations and where schools
faced fewer social problems were more likely to show
improvements.
Era 2 was an era of strict test-based accountability
measures and bold initiatives that were enacted to trans-
form high schools (e.g., changing graduation require-
ments so that all students took a college preparatory cur-
riculum). There were large investments in infrastructure
and stability in district leadership. Test scores in the
elementary/middle grades rose during this period, and
they improved in schools serving students of all types of
backgrounds. This was the only era to show large im-
provements in the lowest-achieving schools. Prior CCSR
studies have found that the test-based accountability
policies, which held schools accountable for improve-
ments in test scores and required students to pass tests
to be promoted from certain grades, had mixed results
for students.

They encouraged teachers and parents to
provide more support to the lowest-achieving students,
and they encouraged better alignment of instruction to
grade-level standards. At the same time, they resulted in
a narrowing of the curriculum to focus on tested subjects
(reading and math), more instructional time spent on
test-taking practice, and a large increase in grade reten-
tion in the elementary schools. Test-based promotion
policies resulted in more students entering high school
who were old for their grade level; this had a depressing
effect on graduation rates.

In fact, the improvements in
graduation rates that had been occurring in Era 1 were
set back in Era 2. This dip occurred, in part, because of
the increase in grade retention and also because of the
change in graduation requirements that ended remedial
coursework and required all high school students to take
a college preparatory curriculum.

In Era 3, there were large improvements in outcomes
in the high schools and very little improvement in the
elementary schools. Improvements that had been oc-
curring in graduation rates accelerated, and were seen
in all types of schools, among boys and girls and all
racial/ethnic groups. At the same time, scores on the
ACT rose, even though students were not entering high
school better prepared. Students were learning more
while in high school. In the elementary grades, test
scores dropped—especially in the lowest-performing
schools. Equity declined, so that schools serving
African American students, and those that started out
the era with the lowest levels of performance, were less
likely than more advantaged schools to have improving
test scores.
While the effects of the dominant policies of Eras 1
and 2 are largely understood, much research remains
to be done to understand both the positive and prob-
lematic effects of the policies in Era 3. The decline in
equity, with African American students falling further
behind students from other racial/ethnic groups, is
particularly disturbing and has raised questions about
policies that disproportionately affected African
American students (e.g., the decision to close chroni-
cally low-performing schools and send students to other
schools). One CCSR study showed no improvements
in test scores for students who were displaced by school
closings,

but there is yet to be an analysis of the over-
all effect of the policies on all students and schools.
Another area requiring more study is the rise in student
performance in the high schools. Era 3 brought a much
greater use of data in the high schools to track students
and provide targeted support for passing classes and
college readiness. Further research should investigate
whether this use of data led to the improved outcomes
and, if so, exactly how it happened.
The findings in this report contradict common percep-
tions about district performance over the last two decades.
It has been widely believed that elementary schools have
improved considerably, while high schools have stagnated.
In fact, the opposite is true. These misperceptions arise
because of problems with the metrics that are used to
judge school performance, and differences in the stan-
dards by which high schools and elementary schools are
held accountable. High schools are increasingly being
