The first official Age-Graded Tables were compiled by WAVA and published by National Masters News in 1989. Revisions (taking into account improved performances at all ages) were released in 1991, 1994, 2006, 2010 and 2014 (minor revision). The tables can be applied to five-year age groups or individual ages from 8 to 100. The only official use of the Age-Graded Tables by WMA is in scoring multi-event competitions. But the Age-Graded Tables have been incorporated into track meet management software by Hy-Tek and others and used to determine age-graded winners in many other competitions, especially road runs.
