Each individual is counted only once per career stage, and is included in any career stage where they made progress during the year (for example, if a candidate both tested and reported hours in 2020, they would appear in both career stages). If a Record holder chose not to identify their race, they are not factored in when calculating the breakdown by race; if a Record holder chose not to identify their ethnicity, they are not factored in when calculating the breakdown by ethnicity.
