This indicator is the sum of reported incidents of non targeted attacks on schools, universities and other educational facilities. Non-targeted attacks are not directed at schools but have an impact upon them, either because they may lead to the closing of educational facilities or result in damages to their buildings.  For example, threats that lead to the closing of schools because of security issues related to armed conflict are also considered non targeted attacks and are, therefore, included.

This indicator is the sum of reported incidents of targeted attacks on schools, universities and other educational facilities. Target attacks are attacks directed at schools, universities and other educational facilities. They might take various forms: airstrikes, ground strikes, bombing/shelling, explosions, looting, burning vandalism, etc.
