ISLAMABAD - Portraying miserable state of school level education in Pakistan, the Economic Survey 2010-11 released on Thursday, revealed that a large number of schools had been functional without basic infrastructure and 15,996 government schools in the country are with out buildings. The quality of existing learning environment is evident from the fact that a large number of schools are missing basic facilities - 32.7 per cent schools up to elementary level, 32 per cent are without boundary walls, 33.6 per cent without drinking water facility, 35.4 per cent without latrines and around 60 per cent are without electricity. The survey suggests that for higher accessibility of education, particularly for girls, in low-income households and to enhance the enrolment, the existing schools should be upgraded with the provision of necessary infrastructure to improve both output and quality of education.
