In 1983 the National Association of Legal Investigators approved a continuing education program that requires all Certified Legal Investigators to complete the equivalent of fifty continuing education hours every three years.

The units can be earned through attendance at NALI seminars and those approved seminars offered by other associations; by completing approved courses offered through colleges, universities, and other schools; by giving lectures and by writing articles that meet the NALI Commission for Continuing Investigative Education's standards.
