(1) Criteria for judging:

(a) If you include the cover in the judging scorecard at all, it should be of little importance, unless your contest is specifically designated as integrative of the visual and writing arts.

(b) Title and description matter a little bit, sure. But most contests I've seen place far too much importance on them. The focus really needs to be on the body of the text.

(c) Not including grammar, spelling, and punctuation in the grading rubric is ridiculous.

-If your judges can't master the basics of written communication, they should not be judging a writing contest.

-If you can't master those essential building blocks, you shouldn't be hosting a writing contest.

(2) Key points:

(a) Having minors judging mature works is unethical. Full stop. (Though, note that I don't personally consider minor expletive use 'mature.' Others may vary in their definition.)

(b) Once results are in, it's not very considerate to publicly post everyone's scores, or even just the scores of winners.

-Unless an entrant got a perfect score, it may well make them feel bad, especially if others got higher scores, and everyone can see. The same goes for unflattering critical comments as for sharing numerical scores.

-I know I don't like it when my scores have been posted publicly, or critical comments have been made (either publicly or privately). I don't enter contests to get critical feedback, however, so for others it might vary.
