My daughter is a The Divergent Series fan and when I read the first book of the Series recently, I could swear that I had read something very similar during my teens in the 1980s.
It was a short story about a young boy who was going for an important test that day with his sibling, and he was very worried about the outcome because their society places people in certain careers based on that test.
Eventually the boy gets an "invalid" result and runs away from the test facility and after several pages gets caught and told that he is one of the people that should be able to create tests and decide the fate of other people. Can anyone remember this story?
