The tests are scored in points according to a scale established as follows:
The zero (0) score characterizes the basic level that a person should be able to achieve. This "median" rating will serve as a switch between the insufficient performances (which will then be negative) and those superior (which will then be positive)
The Levels themselves can divided into different categories:
ratings -1 to -5: insufficient performance.
rating 11 and higher: exceptional performance.
rating 5 to 10: athletic performance.
ratings 3 and 4: superior performance.
ratings 1 and 2: average performance.
The base level is obviously variable with age so as to be adapted to each one and to make it possible to evaluate the progressions, or regressions, in particular in the children, teenagers...
This level is also depending on gender. With younger children, level is more or less the same with girls and boys. Difference must be taken into account from pre-adolescence around 11-13 years.
