Following the low quality of teachers in Egypt, they lack basic psychological background that would allow them to deal with students. Corporal punishment is a common practice in Egyptian schools even though it has not been deeply discussed in literature. An example was brought to the media's attention in 2011 when a pre-K teacher was caught on video consistently beating his students harshly. A study conducted by UNESCO on educational equity in world's 16 most populous countries placed Egypt in the middle range in terms of equity of primary and secondary enrollments across governorates in Egypt. But when the wealth component is added to education attainment, the results are not very encouraging. There are significantly higher enrollment rates in wealthier regions at both the primary and secondary levels. This confirms that more efforts are needed to reduce the wealth gap in educational attainment  Academic weekly holidays are on Fridays and sometimes, in addition to, either Thursdays or Saturdays. In addition to some of the state official holidays, religious or secular, there are two main vacations. The school summer vacation starts at the beginning or middle of June and ends around the middle of September. Winter vacation starts from the middle of January and goes to the beginning of February.
