SE in NEAT. PTPG, Pseudo-Tests and Pseudo-Groups method; IRT, Item Response Theory method; IE, Identity Equating; LSSG, Large Sample Single Group; EE, Equipercentile Equating; IRT, IRT observed score equating; KE, Kernel Equating; IRTKE, IRT observed score Kernel Equating. In (A–D), Red, green, blue, and purple lines represent results of EE, IRT, KE, and IRTKE respectively, calculated by IE criterion. In (E–H), Red, green, blue, and purple lines represent results of EE, IRT, KE, and IRTKE respectively; continuous, dotted, short-dashed, and long-dashed lines represent results calculated by EE, IRT, KE, and IRTKE criterion respectively.
