I found this in Arabic that explains it quite well. In some situations, parents are able to home school their children: if schools are bad and students don’t perform as well (or lose their “morals”), if they need assisted learning, or if they are high school students they can take some school courses online and only attend the exams (such as doing the IGCSE). Also seems like there are some institutions that help parents home school children.

We had a building guard in the apartment block where my parents lived who was an Egyptian national and had a daughter and a son and refused to send his daughter to school even though it was illegal in Jordan to not do so. However, most likely due to shitty beliefs + bad economy + Jordanian law for foreigners means that his daughter never made it to school and was just “married off” as soon as possible. My parents pleaded with him right and left but he would not budge. Reporting it to the authorities would most likely mean the girl would have been mistreated. I’m in no way saying this is a normal thing in Egyptian society based on this one perdon, but I’m trying to say that it happens a lot with a certain demographic and those kids need our help as adults around them.
