To set a valid criterion-referenced standard, the fitness gram scoring has both scientific knowledge and measurement expertise. They set standards based on expert judgment, knowledge of the score distribution of the field test and the criterion test within the population, and the relationship between the field test and the criterion measure. The standard represents the level of risk for the health outcome related to the fitness
component being tested. Fitnessgram uses a range of scores called the Healthy Fitness Zone for their tests.
