WebApr 21, 2024 · Test equating is used to ensure that test scores from different test forms can be used interchangeably. This paper aims to compare the statistical and computational properties from three equating frameworks: item response theory observed-score equating (IRTOSE), kernel equating and kernel IRTOSE. The real data applications suggest that IRT ... WebBut now that IRT equating is widely available, is there any reason to equate test scores any other way? Indeed, IRT equating has some important advantages. IRT offers tremendous …
WebTest equating traditionally refers to the statistical process of determining comparable scores on different forms of an exam. [1] It can be accomplished using either classical … WebMar 7, 2024 · To equate IRT scores under the IRT setting, we need a transformation function that maps the IRT scale on test form X to that of test form Y, i.e., \(\varphi:\varTheta _{\mathcal{X}}\mapsto \varTheta _{\mathcal{Y}}\) (see, Definition 1.1).The transformation of IRT scales will be different depending on the equating design adopted.
WebItem response theory is used first as a flexible mean of equating test papers with overlapping items. However, there is off-level effect (or out-of-level effect) in putting students with very different ability level together (O'Brien & Tohn, 1984).
