Regulatory agencies have been given extensive powers to address public concern about the use of pesticides. To receive a pesticide applicator license in most states, individuals must pass certain federal and state certification examinations (Farm Chemicals Handbook, 1996). Training programs may or may not be effective in preparing individuals to pass federal and state required certification examinations. The study discussed here examined the effectiveness of a pesticide training program conducted under federal law. Data collected from course providers and license applicants reveal that this educational program substantially improved the performance of license candidates and should be continued and expanded.
