Millennium Development Goal 2: Achieve universal primary education
Target: Ensure that, by 2015, children everywhere, boys and girls alike, will be able to complete a full course of primary schooling
The latest survey data indicate that around 90 per cent of children entering primary school remain in school until the final grade.
Higher enrolment in primary education is, however, leading to concerns that educational quality needs to keep pace to ensure that children completing primary school have a strong foundation for further learning.
Enhanced quality will have multiplier effects, enabling enrolled children to have higher rates of attendance and completion, better learning outcomes, and increasing rates of transition to the next level of education and to meaningful employment.
