Fischer wrotedo those schools teach schools teach anything in arabic? The kids don't know arabic at all
I don't know about specific schools, but a cousin recently moved to Lebanon. She's 13 and could barely understand arabic, never mind reading or writing. She went to IC (International College) in Zgharta (?). She was in a special program for a while, where they taught her remedial arabic, and now, apparently, she's doing very well and can read and write just as well as everyone else.
Also, similar story with another family. They moved back, the kids who I believe were 10 and 11, didn't know any Arabic. They ended up going to College des Apotres in Jounieh, which is a French system school. They also were part of a special remedial program for French and Arabic. After only a few months, they were able to join everyone else in their respective classes.
I'm not saying it's an easy process, but I believe kids at that age can do well, and adjust pretty quickly if they are willing to work hard.
