This amendment modifies a component of the school grades calculation requiring adequate progress for the lowest performing quartile of students in reading and in math. Under the current rule, for schools that have earned enough points to receive a school grade of “C” or higher, adequate progress is demonstrated if at least 50 percent of these students make learning gains in each subject. If adequate progress is not demonstrated, the school will receive a final grade that is one grade lower than the school would have received otherwise. The amendment allows schools that fall short of the 50-percent mark in this category to demonstrate adequate progress if (1) for schools with at least 40 percent of such students making learning gains, there is annual improvement in the percent making learning gains; or (2) for schools with less than 40 percent making learning gains, there is at least a five-percentage-point annual improvement in the percent making learning gains.
