Enrolment and success rates are very crucial for any educational system in the world but they are more important for the developing countries like Bangladesh. Gender differences in enrolment and success rates are also emerging issues. This study investigated the enrolment and success rate’s status in secondary educational system of Bangladesh along with internal efficiency rates involving completion rate, retention or survival rate, dropout rate and gender parity index. Some tests of hypotheses of homogeneity were also conducted. Among the findings higher female enrolment rate, lower female success rate, higher male completion rate, survival rate and higher female dropout rate were perceived along with different location, types of schools variations. Some policy implications were suggested with acknowledgement of some flaws in the female stipend Program in Bangladesh.
