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.	The Bookmark method is an item-response-theory-based standard-setting procedure in which test items are arranged in a booklet ordered from easiest to hardest. Panelists page through this ordered item booklet and place a 'bookmark' at the point separating items a borderline examinee would likely master from those they would not, judged against a fixed response probability (commonly two-thirds). The latent ability at the bookmark defines the cut score. Developed at CTB/McGraw-Hill, it became one of the dominant methods for large-scale K-12 assessments.
