In West Bengal both English and Bengali medium schools are available and therefore the present study attempts to analyse the students'' level of achievement in English and Bengali languages in English and Bengali medium schools. We earnestly hope that the findings of the present study will help in redesigning the curriculum of English language teaching, and mother tongue teaching in the schools of West Bengal. The present study critically reviews the current English language teaching methodologies used in the Bengali medium school.
