What belongs on a route sheet

Leave student names off. The table number finds the project, and the sheet is often left on a clipboard in a public hall.

Walking order without slots

Without slots, the assigner prints each judge's projects in walking order: room by room, row by row, table by table. It also tries, while it assigns, to give each judge projects close together, counting a room change as 4 steps, a row change as 2 and each table between as 0.1, up to 2 along one row, so a judge in the gym is not sent to the library and back.

Schedules with time slots

With slots, each visit gets a time. A judge is in one place at a time, is only given slots inside the hours they said they are there, and a project hosts at most as many judges at once as you allow: one for the classic walk round, the whole panel when judges interview together. One regional judging guide listed below plans about eight to ten minutes per project, which is a sensible slot with a short walk.

Worked example: twelve ten minute slots

The sample fair in the judge assigner was given 12 slots of 10 minutes from 09:00 to 11:00, one judge at a table at a time. The assigner filled 108 of 108 seats with 0 broken rules. This is Marcus Bell's route sheet as it prints:

Gaps in the times are free slots: a judge with fewer projects than slots gets breaks, which is where late interviews and lunch go.

Frequently asked questions

What is a judge route sheet?

A single page a judge carries round the fair: the projects they are to judge, in the order to visit them, with table numbers, rooms, times if the fair uses slots, and a box to tick when each is done.

Should judging use fixed time slots?

Use slots when students must be at their boards at set times, when judges arrive and leave at different times, or when several judges must not crowd one table. Without slots, judges walk their list in table order at their own pace.

How long should a slot be?

Long enough for the interview plus the walk to the next table. One regional guide plans eight to ten minutes per project; a hackathon guide plans about four minutes per judge visit, travel included.

What goes on the sheet besides the route?

The judge's name, the fair name and date line, and nothing that identifies a student. Scores go on the separate scoring packet, which the assigner prints with your own criteria.
