In this paper we have given a methodology to estimate the correlation coefficient between Combined Admission Test (CAT) score and Cumulative Grade Point Average (CGPA) of the students by truncating the CAT score at different cut-off points. An expression for asymptotic variance of estimated value of correlation coefficient has been derived for testing the hypothesis H0: r = 0 against the alternative H1: r > 0.
