Random testing is exactly that - random. Employee names are entered into a computer system, and the computer selects those to be tested.
For employers who are required to perform DOT testing, the percentages are required and set by the operating administration regulating the employer, such as the FMCSA or FAA. Refer to this document for Best Practices for DOT Random Drug and Alcohol Testing issued by the U.S. Department of Transportation:
For non-DOT testing, the employer has to make decisions regarding which employee categories to include in the random pool, the frequency of testing, and the percentage of the employees to be selected for testing. The computer needs the employee names, a unique identifier, such as an SSN or employee ID #, the frequency of testing (monthly, quarterly, etc), and the percentage of the employee population to test through the yearly program (25%, 50% etc). Computer generation of the folks to be selected is important so that there is a system to produce unbiased random selections of personnel subject to drug and alcohol testing. In addition, there should be safeguards in place so that the software operator can in no way manipulate the selection process.
