The Chronicle of Higher Ed. reports that the earthquake that struck California last week happened five minutes before the bar exam was finished, and some of the test-takers had to dive under their seats. Apparently some of them were allowed an extra five minutes and some weren't, so there is some controversy.
A notice (pdf) posted on the California bar website reassures visitors that in light of the earthquake "During the grading process the Committee’s psychometric consultant has been asked to perform a psychometric study on whether the earthquake impacted applicants’ performance on the first session of the examination and to report his findings to the Committee prior to the release of results from the examination. " It adds "While the Committee regrets that this incident occurred, the fact that it did was beyond its control."
