When a student completes an ISAT test, he or she receives a series of RIT scores as a result. So, what is a "RIT" and what do the scores mean?
"RIT" is an abbreviation for "Rausch Unit." The difficulty and complexity of each ISAT test question is measured using the RIT scale. A student's RIT score indicates that the student was answering questions correctly 50% of the time at that level of difficulty.
