This paper presents the findings of a study which aimed at exploring the washback of the Secondary School Certificate (SSC) English examinations on English teaching and learning practice at secondary schools in Bangladesh. For this purpose, a qualitative research (employing interviews with English teachers, FGDs with students and classroom observations protocol) was conducted in 12 secondary schools. The results from data analysis indicate that the SSC English tests had strong negative washback on English teaching-learning practice at secondary schools resulting from a lack of a congruence between the objectives of the curriculum and the format of the tests, teachers' lack of adequate understanding about the curriculum and present assessment system, respondents' negative attitudes towards the test, and pressure from the schools and the parents to ensure good grades in the final examination. Consequently, teachers and learners adopted such teaching and learning approaches which are highly examination-oriented. The study puts forward some suggestions on how positive washback could be generated. The findings of the study have implications for the decision makers, designers of curricula, assessment and testing, teachers, and teacher trainers involved in the Bangladeshi educational system and elsewhere.
