For the timed tests (handstand,sprint,jump,rope) 9 year olds are compared with other 9 year olds across the country, 10 year olds compared with other 10 year olds, and then points are awarded (10 pts to the top 10% in that category, etc). 10 year olds can on average jump higher and run faster than 9 year olds, so usually a faster time is required to get in the same percentile.
