Understanding best practices for Consortium/Third-Party Administrators (C/TPA) is a crucial step in selecting and working with a drug and alcohol testing service provider.

C/TPAs play an essential role in the implementation of many corporate drug testing and alcohol testing programs. They manage all or part of an employer's program, maintain records and offer a variety of other related services agreed to by both parties, including subcontracting with specialized service providers as needed. Whether the C/TPA manages all or just a portion of the program, its main focus is to help keep the employer compliant with Department of Transportation (DOT) and Federal Motor Carrier Safety Administration (FMCSA) regulations and to alleviate both the effort and cost of establishing an in-house department responsible for the same.

While the number of C/TPA agents marketing suites of customized services to meet the particular needs of their clients continues to grow, selecting the right service provider for your organization has become increasingly more competitive and complicated. Before choosing your C/TPA, it is important to know how current state and federal regulations impact the work you do. Although each company (yours included) is unique and will have its own needs, a brief internal analysis will provide some foundational information to inform your future discussions with potential C/TPA service providers.

Questions To Consider In Discussions With Potential C/TPA Service Providers

  1. Does your company operate in one or multiple states?
  2. Do you have both non-DOT and DOT employees? (Learn more in Guidelines for Employers With Both DOT And Non-DOT Employees).
  3. Is there a Drug-Free Workplace program requirement in your state?
  4. Do you have internal resources such as a program manager or safety committee already in place to work with the C/TPA?

Once you have an understanding of how your operations may affect the services you require from a C/TPA, the next step is to research C/TPA best practices as they relate to your company. A review of C/TPA best practices will make your decision easier when selecting a drug and alcohol testing program that is the best fit for your organization. This review should be done as part of your preparation process and used as a part of the formal service provider interview. Details from the interview can be used to prepare specifics for the final contract.

Here are some examples of best practices that should be discussed with potential C/TPA services providers and used as part of a regular review cycle for those already under contract:
