Nationwide Testing Association, Inc. began substance abuse testing programs for the workplace in 1986, primarily for USDOT regulated employers. As Drug Free Workplace guidelines became more prevalent nationwide in the early 1990’s, NTA, Inc. added those services for non-DOT regulated employers. In addition to our substance abuse management programs, we offer a full range compliance, training and investigative reporting services. Substance abuse management is one of the better tools in the prevention of any potential threats to staff, customers, and shareholders. Studies have shown that drug and alcohol testing programs reduce costs associated with absenteeism, accidents, and counterproductive work. NTA, Inc. will customize a substance abuse testing program to meet your specific needs.
