According to the World Bank, the estimated net attendance rate for primary and secondary education in Afghanistan was 59% in 2018. This rate was higher for boys (65%) compared to girls (53%). The attendance rate varied across different regions of the country, with higher rates in urban areas compared to rural areas.
However, since the Taliban took control of Afghanistan in August 2021, there have been significant changes in the education system. The Taliban initially announced that girls would be allowed to attend school, but later issued restrictions that limited their access to secondary and higher education. As a result, the percentage of children attending school, particularly girls, may have declined.
Given the ongoing developments and challenges in Afghanistan, it is difficult to provide a precise and up-to-date figure for the percentage of children attending school. For the most current and accurate information, I recommend consulting reputable sources such as international organizations, reports, and news agencies that track education statistics in the country.
