The Law School Admission Council (LSAC) National Longitudinal Study was undertaken primarily in response to rumors and anecdotal reports suggesting bar passage rates were so low among examinees of color that potential applicants were questioning the wisdom of investing the time and resources necessary to obtain a legal education. This study presents national longitudinal bar passage data gathered from the class that started law school in fall 1991. Data provided by students, their law schools, and state boards of bar examiners over a 5-year period are included in the summaries and analyses in the report. Summary statistics, graphical illustrations, and mathematical models were used to analyze and present the data. The eventual bar passage rate for all study participants was 94.8% (21,886 of 23,086). The eventual passage rate for all participants of color was 84.7%. The passage rate was lowest for African Americans (77.6%, or 1,062 of 1,368) and highest for White participants (96.7% or 18,664 of 19,285). Eventual pass rates were substantially higher than initial pass rates, and there were no differences in bar passage rate between men and women. Both law school grade point average and Law School Admission Test (LSAT) scores were the strongest predictors of bar examination passage for all groups studied. Although students of color entered law school with academic credentials, as measured by undergraduate grade point average and LSAT scores that were significantly lower than those of white students, their eventual bar passage rates justified admission practices that look beyond those measures. Five appendixes contain forms used to conduct the survey, some data analysis, and an explanation of the use of log odds. (Contains 9 figures and 39 tables.) (SLD)
