The purpose of this study was to perform an IRT analysis of Wong and Law Emotional Intelligence Scale (WLEIS: Wong & Law, 2002). The sample consisted of 481university students in the province of Balochistan, Pakistan. After examining the unidimensionality of WLEIS four sub-scales, graded response model for seven ordered categories was applied (Samejima, 1969) using "ltm" an R package (Rizopoulous, 2006). Results indicated that the WLEIS sub-scales yield precise measurement for individuals with low to moderate trait levels and relatively imprecise measurement for individuals with high trait levels.
