Will the award be sponsored like the Campbell’s? Will the award be named for a person? How will the votes be tallied? How will the category be defined? By age, by marketing category, or by general ‘teen’ designation? Will the award be for science fiction/fantasy or speculative fiction? Will the award be called ‘YA’, ‘teen lit’, or some other such thing? Will there be a word length limit, such as 40,000 words? Details of the sunset clause? The issue of dual eligibility?
The Sasquan report has a good breakdown on how various other awards determined what was YA, what was middle grade, and the pros and cons of using marketing categories.
The report of this year's YA Award Committe doesn't have a direct link (yet). It can be found starting on page 37 of the pdf of the WSFS Agenda for the Business Meeting. If you don't want to read through the pdf, the good news is that the YA Award Committee decided that the Award should be treated like the Campbell Award (not a Hugo), so that a strict definition of what constitutes YA wouldn't be needed, nor would a word limit (which is what determines several of the categories of the Hugos).
The bad news is that the Committee couldn't decide on a name for the award. The report goes into their decisions against naming the award after any one particular author. Instead, they recommended, if the award proposal passed, to create a committee to collect and evaluate name ideas. Which means an actual award would be delayed at least another year.
The Facebook page for YA Hugo Proposal posted that the YA Award proposal passed. That page will also put up links to where you can submit suggestions for the name of the award once links or an email is announced.
For those interested in the procedure of the meeting, Rachael Acks Liveblogged from the Business Meeting on August 19, 2016. The section on the YA Award is 1015-1029. The August 20 meeting covered the YA Award from 1144-1201 (there's also a quick summary).
Here's hoping next year's WorldCon in Helsinki will finally see the creation of a Young Adult Award!
