Sammendrag	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.	Vertical scaling places tests written for different grade levels onto a single continuous score scale so that growth from one grade to the next can be measured in common units. Unlike horizontal equating, which links alternate forms intended to be interchangeable, vertical scaling deliberately links tests of differing difficulty and content to build a developmental continuum spanning, for example, grades 3 through 8. It is the measurement foundation that lets a fourth-grade and a fifth-grade score be subtracted to express how much a student grew.
