Reading comprehension is the procedure of making meaning from text. The goal, therefore, is to gain an overall understanding of what is described in the text rather than to get meaning from isolated words or sentences. The objectives of the study were to compare the reading comprehension ability among the students with different Socio- Economic status (SES). It was tested by Socio- Economic Status Scale and two types of comprehension tests. Tests were administered on 684 samples from 16 schools of West Bengal. The collected data were analyzed by statistical procedure ANOVA. The major findings were observed that in M.C.Q. Test, students with high and moderate SES are better than low SES, whereas students with moderate and high SES do not differ from each other. In the performance of Cloze Test high and moderate SES are scored better than low SES, and also found high SES is better than moderate SES. In the performance of both test (MCQ Test & Cloze Test), students with moderate and high SES are better than students with low SES, and also found high SES is better than moderate SES. The probable causes behind this type of result were discussed.
