Employees in a defined pool are chosen using a scientifically generated random process, so every person has an equal chance of selection at each draw. The selection is documented to keep the program defensible, and selected employees are notified and tested promptly to preserve the integrity of the random draw.
Random drug testing is a program in which employees are selected for drug or alcohol testing on an unannounced, scientifically random basis rather than on a fixed schedule. Because employees cannot predict when they will be selected, it works as an ongoing deterrent to substance use and helps maintain a drug-free workforce.
