The ATL School and Firm Insiders Survey asks self-identified current students, alumni, and practicing lawyers to rate major aspects of life at their law school (academics, social life, clinical training, career services, financial aid advising) and/or law firm (compensation, hours, morale, culture, training). We then translate these ratings into letter grades, where the mean score for each particular ratings category is the equivalent of a “B.”

We require a minimum threshold of responses for each institution before we publish any survey-based ratings content. Using a standard formula for statistical validity, we adhere to a threshold that gives us an 85% confidence level and a 10% margin of error. The precise threshold number will of course vary depending on the size of the individual institution. For example, for a law firm of 1,000 attorneys, we would require 50 responses in order to publish ratings for the firm.
