“…As with examinee covariates, interest in the relationship between item characteristics and various ancillary data extends beyond the domain of score comparability. Applications include difficulty or item parameter prediction (e.g., Baldwin et al., 2004; Collis et al., 1995; Hall & Ansley, 2008; Irvine et al., 1990; Mislevy, 1988; Nungester & Vass, 1985; Scheuneman et al., 1991; Stowe, 2002; Swaminathan et al., 2003; Wang & Jiao, 2011; Xie, 2019); response time prediction (e.g., Halkitis et al., 1996; Parshall et al., 1994; Smith, 2000; Swanson et al., 2001; Baldwin et al., 2021); evaluation of automatically generated items (Leo et al., 2019; Kurdi, 2020; Benedetto et al., 2020); item pretest survival prediction (Ha et al., 2019, Yaneva et al., 2020); response process complexity estimation (Yaneva et al., 2021); and differential item functioning detection (Sinharay et al., 2009). Nevertheless, while researchers have sought to capitalize on item covariates to improve a broad range of activities, they have not been widely used to facilitate score comparability.…”
