North Carolina students in grades 3 through 8, including those attending charter schools, are required to take End-of-Grade (EOG) standardized tests to evaluate their progress in three core subjects. Each student receives an EOG score that demonstrates how well they're performing.
The EOG exams test students in reading, mathematics and science. The number of correct answers by each student provides a raw score that is converted into a developmental scale score.
EOG scores are ranked on a scale of one to four achievement levels, with the fourth achievement level being the highest. The exact number needed to reach each achievement level varies, depending on the subject.
Students in grades 3, 5, and 8 must post an EOG score at achievement level three in order to advance to the next grade.
EOG scores help the North Carolina Board of Education gather information to monitor each individual student's performance and the effectiveness of the entire school system.
A Duke University study found that exposure to lead early in childhood lowered EOG reading scores in minority and low-income children.
The EOG statewide assessment program began in 1996.
