The law also required annual statewide
tests in grades 3 through 8, and again in high school, and
states had to publish the performances of students on these
tests for every school,
breaking out the
results by ethnicity, eligibility for a subsidized lunch, and a variety of other categories.
Each year, the teams pore over the
results of the
state test, which are
broken down to show every teacher how his or her students performed on every skill and on every
test item.
NCLB has been widely praised for its requirement that
states and schools
break down their
test results by subgroups — across racial, socioeconomic and other lines — to highlight achievement gaps.
