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.	Standardized test analysis is the body of psychometric methods used to evaluate and score standardized educational tests: analyzing how items perform, estimating reliability and the standard error of measurement, scaling scores via classical or item response theory, and assembling validity and fairness evidence. Governed by the professional Standards for Educational and Psychological Testing and rooted in test theory synthesized by Lord and others, it is the disciplined work that turns a set of test questions into defensible scores carrying meaning, precision, and fairness.
