The Congregation of Holy Cross has been working on evangelisation and education in Bangladesh for more than 170 years. This study examines the educational mission of the Congregation in Bangladesh. The study is conducted from a historical perspective. The paper is based primarily on the examination of written documents -- primary and secondary -- and field work involving oral history interviews. The study identifies four primary aims of Holy Cross education in Bangladesh. The paper argues that they have distinctive educational aims at the nation's elite education both through English and Bengali medium, and villages' primary and secondary level education. The study illustrates that there has been a shift of emphasis on the educational mission over the years. A significant contribution to the changing mission of Holy Cross education has been the independence of Bangladesh. Another factor that contributed significantly to changes in Holy Cross education has been the Catholic Church itself and the structure of Catholic life, as a result of Vatican II. Mission models that emerged after the Council emphasised social justice and religious pluralism. Those teachings of the Church brought changes to the educational missions of Holy Cross in Bangladesh.
