Georgia students showed improvement in most subject areas measured by end-of-course tests, which are now more important than they were before.

The tests -- 20 percent of a student's final grade as opposed to the 15 percent they represented before -- showed improved performance in U.S. history, economics, biology, physical science, ninth-grade literature, American literature and mathematics I.

The results offer a district-level look at the statewide results released earlier this month. School-level results are expected to be released before the end of July.

Beginning with the upcoming school year, end-of-course tests will be used as a factor in determining a school's progress in Georgia's college and career readiness performance index.
