Assign science fair judges without the spreadsheet all-nighter

How it works

  1. Paste the projects. One per row: a project code, title, category, division, table or board number, room, school, and optional student initials and special flags. A header row is read if there is one.
  2. Paste the judges. Name, school or employer, the categories they can judge, expertise tags, conflicts, the hours they are there, and the most projects they will take.
  3. Set the rules. Judges per project, projects per judge, whether a category match is required or preferred, no two judges from one school on a panel, and rounds and time slots if you run them.
  4. Assign. Hard rules are never broken silently: a project that cannot get every judge it needs is listed with the reason, judge by judge.
  5. Review and print. Drag a judge to another project and the conflict flags update as you move. Lock what you are sure of, rebalance the rest, and print route sheets and judge lists.

What you get

Fairness is your call

Judgegrid does not score projects and does not decide who is a good judge. The tool only applies the rules you enter, and it tells you plainly what it could not do. No rubric text is shipped: scoring packets carry the criteria you type.
