What balance we've struck is that coaches keep track of their results - say, to the nearest 4 inches in the long jump pit, we've labeled the edge in 4" increments and see how they fare without making a fuss of it.

Then, at the close of the season, we typically note that everybody has made significant progress, and then it's time for 'Listen, Ken, when we first started outdoor season, you jumped here - and now (big stride!) - now you jump HERE.'

I would be most surprised if any kid felt under pressure to improve from their previous best; however, kids, like adults, tend to like both to make progress and to know that others notice, too.
