The Bar Exam is an examination taken by candidates wishing to practice law in a given jurisdiction. In the United States, the bar exams and the standard of who can take the bar exam differ by state, but generally the exam is given over a period of two to three days, and uses essays and multiple choice questions to determine whether a candidate is qualified to practice law. Many jurisdictions use the Multistate Bar Examination (MBE), a standardized multiple-choice examination, along with essays covering state law. Some jurisdictions use the Uniform Bar Examination (UBE), which is uniformly administered and graded, so that the score is portable between user jurisdictions.
