You should also know that it is possible to get credits whether or not you've actually had any schooling. I went to a therapeutic boarding "school". I went to class, perhaps, 3 weeks of my entire 7 month stay. When in class it was impossible to learn anything because of the level of abuse dealt with, and because we attended classes that had been in progression since the beginning of the year, without us. Kids attend school for one third of the time (at best) that the school runs. School is a "privilege", and if your participation depended on where you were in the program, whether you were doing some "work assignment" (kids handled all maintenance duties at school) or some other sundry slave or recruitment service. Suffice to say, there was NO actual education, however this "school" issued diplomas. So, you can get some kind of "credit" or "education", but it will only exist on paper.
Of course the idea that education is possible in a situation where you have been abducted and imprisoned without any form of due process, in an act of extraordinary rendition, is absurd.
I’m sorry, if parents have any level of competency they would know better than to expect education in such a circumstance.
