Southeast Bulloch High School continues to lead the way on most End-of-Course Tests, but Portal Middle High is closing the gap, according to results released this week. Southeast Bulloch High posted the highest pass rates on six of the eight state-mandated tests. Portal took top honors on math I, in which its pass rate leaped nearly 26 points from 2011 to 71.7 percent of students passing in 2012, and physical science, which saw a 7 point improvement to 80.1 percent passing last school year.
