Only those who have the appropriate certifications and expertise can value a business in the context of submitting expert testimony in a court of law or for filings with the Internal Revenue Service. Since 1991, The National Association of Certified Valuators and Analysts (NACVA) has been at the forefront of the valuation / appraisal industry. They have trained and certified experts through developing a rigorous 45 hour course, extensive testing, and peer reviewed test case valuations. In addition, they require 40 hours per year of continuing education.
