In April 2011, the state Board of Education approved a plan to phase out the Georgia High School Graduation tests beginning with the class of 2015. State officials say end-of-course tests, which began in Georgia last year, are a better measure of how much students have learned.
Students showed the biggest gains in economics, with 77 percent passing, up from 72 percent last year.
There was a one percent decrease in the number of students passing the Mathematics II exam, which includes geometry, Algebra II and statistics. Fifty-four percent of students passed that test this year.
