In a written reply to a question in Rajya Sabha, HRD Minister Smriti Irani said, "Overall the annual average dropout rate at primary level has reduced from 5.6 per cent during 2012-13 to 4.3 per cent during 2014-15."
In a written reply to a separate question, Irani said lack of toilet facilities in schools for girl child has been one of the reasons for girls to dropout from schools.
Several other north eastern states - Mizoram (13 per cent), Arunachal Pradesh (10.9 per cent), Meghalaya (10.3 per cent) - have a dropout rate in double figures, far above the national avarage.
Assam has a dropout rate of 7.4 per cent while Sikkim had a dropout rate of 4.6 per cent during 2014-15. Tripura, however, was an exception, showing a dropout rate of 3.6 percent, lower than the national average.
