Basic Education in Science Fiction or Fantasy

By basic education I mean a lot of those things that most of us take for granted, like reading and writing and basic arithmetic. In a less developed world, whether it's fantasy or science fiction, we may have a setting where the children are expected to work. The same can exist in science fiction depending on the technological level and what's currently going on. We don't need to invent an entire curriculum for what people learn, we can just decide on the basic level of education for most people in our setting. Unless we need a character to have a specific kind of ignorance compared to everyone else, this is usually fine.
