Independent Contractors


Abt Associates frequently partners with technical experts for short-term assignments. It is our policy that, when needed, we will contract for services from qualified individuals through the use of consulting agreements. A consulting agreement is entered into only after a good faith assessment is made to determine if the individual meets the definition of an independent contractor, consistent with U.S. Internal Revenue Service (IRS) guidelines, state laws and international standards.
