Former test chair....also my DD tested (and passed!)her Juvenile FS today
Dance and Moves are supposed to get cleaner ice. Higher tests are supposed to get cleaner ice. Sometimes a test chair has to work around a schedule...either a skater or a judge. For example today, there a senior and 2 junior moves tests (all same warm up). They were followed by a Preliminary Moves and Preliminary Free Skate, and then 2 Intermediate Moves tests. The 2 Preliminary tests were sisters. One had soccer try-outs so they needed to test early.
Sometimes I would put pre-pre and preliminary moves/FS first, because they only require one judge. If one of my judges was coming from work or a long distance away, I would usually do the one judge tests first. That way I could keep my schedule moving. I have had judges get lost or stuck in traffic before.
Usually free skates get put before an ice cut/scrape/resurface, but not always. Today, there were a Jr FS, IM FS, and 2 Juv FS right after the intermediate tests. This was to accomodate a coach who had SRM, JRM, IM, and IF tests. That way she could leave and not wait until all the rest of the moves and fs tests were done. The Preliminary FS tests were done at the end of the test session.
