概要	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.	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.
