The main focus on YA literature comes from written examples and exercises. Brooks will ask you to go back in time to your teenage years and focus on your preoccupations. She also lists teen character traits, plots that involve family and school issues, as well as settings youth would most likely be chilling at.
Although, adding a list of YA literature classes students may take in American Universities doesn't help us Canadians, she does explain the variety of awards (YALSA) YA books can merit as well as publishing houses, and manuscript format and submitting procedures.
