Nigeria accounts for over 50% of the world's out-of-school children

More than half the world's children who are not being educated are in Nigeria. 60% of Nigerian children not attending school live in the North of the country.

Most affected were girls, street children and the children of nomadic groups.

In a speech delivered to educationists in Kano, Adamu Husaini , Permanent Secretary of Nigeria's Ministry of Education said it was "sad to note" that the highest number of out-of-school children in the world - 10.5 million out of 20 million - were in Nigeria.

He added:The recent decades witnessed heavy donor agencies and government intervention on education to address the problems. But, the reality remains that there is still low attendance and low attainment and completion rate among the marginalised and vulnerable groups"
