The RD exam is not graded on a percentage, but on a scaled score system of 1 to 50. This means you do not need to answer a specific percentage of questions correctly to pass. Instead, you must achieve a minimum scaled score of 25, a complex calculation determined by the Computer Adaptive Testing (CAT) format.
