概要	The Angoff method is a test-centered procedure for establishing a passing score (cut score) on an examination. A panel of content experts conceptualizes a 'borderline' or minimally competent examinee and, for each item, estimates the probability that such an examinee would answer it correctly. Summing those probabilities yields a recommended cut score for each panelist, and averaging across panelists and discussion rounds produces the performance standard. It is among the most widely used standard-setting methods in licensure, certification, and K-12 testing.	Test equating is a family of statistical methods that converts scores earned on one test form onto the score scale of another form, so that scores from different administrations or versions can be compared and reported on a common metric. The foundational modern treatment is Kolen and Brennan (2004/2014); Holland and Dorans (2006) provide the authoritative chapter-length overview within the field of educational measurement.
