The earliest evidence of examinations in Europe date to 1215 or 1219 in Bologna. These were chiefly oral in the form of a question or answer, disputation, determination, defense, or public lecture. The candidate gave a public lecture of two prepared passages assigned to him from the civil or canon law, and then doctors asked him questions, or expressed objections to answers. Evidence of written examinations do not appear until 1702 at Trinity College, Cambridge. According to Sir Michael Sadler, Europe may have had written examinations since 1518 but he admits the "evidence is not very clear." In Prussia, medication examinations began in 1725. The Mathematical Tripos, founded in 1747, is commonly believed to be the first honor examination, but James Bass Mullinger considered "the candidates not having really undergone any examination whatsoever" because the qualification for a degree was merely four years of residence. France adopted the examination system in 1791 as a result of the French Revolution but it collapsed after only ten years. Germany implemented the examination system around 1800.
