Your official GED® transcript contains two sets of numbers: standard scores and percentile ranks. The standard scores make it possible to compare scores across tests and test forms. This is necessary because some tests contain a different number of questions and there are many forms of the GED® test in circulation, all of them of equal difficulty. The percentile rank makes it possible to compare your performance on each one of the tests with the performance of graduating high school seniors. The higher the percentile rank, the better your performance.
