Predict Your Law School Class Rank
Test Version 11/8/2014
This is a law school class rank calculator that uses publicly available data to predict law school class rank based on LSAT and undergraduate GPA. The calculator itself is fairly accurate for LSATs and GPAs that are between the 25th and 75th percentiles for each school. Its accuracy decreases for very low or very high LSATs or GPAs for a particular school.
Although the calculator itself is fairly accurate within those ranges, its results demonstrate that law school class rank is not at all predetermined based on LSAT and undergraduate GPA. Students with relatively low LSATs and GPAs at a particular school still have a decent shot at the top third of the class, and those with relatively high LSATs and GPAs still have a decent shot at the bottom third of the class. In other words, there is much more to law school success than high predictors.
This calculator is a work in progress and I expect to update and improve it as more information becomes available to me. Comments are welcome!
The reason that LSAT and undergraduate GPA do not predetermine your class rank is not because they are not good predictors. Although not perfect, LSAT and undergraduate GPA are reasonably good predictors for the purpose for which they are used--law school admissions. The reason they don't predict your class rank very well once you're in law school is that each law school's students are very highly stratified with a thin range of predictors.
Yes, some will have a higher LSAT and lower undergraduate GPA and vice versa, and some will have overall higher predictors but still attended a school because they received a merit scholarship or for other reasons. Overall, however, the vast majority of students within a particular school are within a very narrow band in terms of the "index" for admissions, and therefore LSAT and undergraduate GPA don't predict very well within schools even though they differentiate well between schools.
More to come! Let me know what you'd like to see changed in the comments.
