Found out how it works at son's school.
20 percent of team are tested each testing period.
Everyone's name in a hat and 20% of kids names or drawn each time.
I guess it is possible some could never be tested and some could be tested everytime. No big deal, but was curious how it was done at other schools.
Thought thier might be a uniform policy for all schools. Apparently each school can administer it's testing as they see fit. As important as it is to rid drugs out of sports you would think their would be a more uniform system of testing. JMO
