By including the "repeaters" with the first-time takers, you can get an "overall" pass rate for a law school, but you have to consider exactly what that number is telling you. Because people can sit for the Texas bar exam five times, the "repeater" number can include people who have been trying to pass the exam for up to five years (if the person is, say, only sitting for one of the two bar exams offered every year after they graduated). And we don't know from the data if there are more repeaters from, say, one graduating class than another. It's probably safe to assume that most "repeaters" in a February exam are by and large people who failed from the previous July, but the exact numbers are not shown on the Texas Board of Law Examiners' website. The "repeaters" are all lumped together. And some people, after they fail the first time, only sit for the July exams thereafter. They do this because some people say that the February exam is slightly more difficult to pass than the July exam.
Also, US News & World Reports lists only the first-time taker number in their publications and it is the first-time taker number that is the factor that goes into their rankings. The ABA is also concerned with the first-time taker number. Kudos to Baylor for being number one.
