Quran lessons can be seen on some pictures at the Tuba Camii (from 1984), where I ran into a group of kids memorising the Quran. I was shown around by their teacher who explained they lived here as interns (in rooms I was shown also, downstairs from the mosque) for two years, after which some would become imams, others would become lay workers. The Quran was taught here, the general education was at a nearby school.
