One of ACUS's primary statutory functions is to make recommendations for action by federal agencies, the President, Congress, and the Judicial Conference of the United States to improve administrative procedure.

Recommendations are developed by committees of ACUS members, typically with the support of expert consultants and ACUS staff, and are adopted by the full membership at twice-yearly plenary sessions. Adopted recommendations are published on the ACUS website and in the Federal Register. The Chair and ACUS staff undertake activities to encourage federal agencies to carry out recommendations adopted by ACUS.                                    

ACUS sometimes adopts “Statements,” which express the agency's views on a particular matter without making a formal recommendation. Statements are developed through the same process as recommendations but typically set forth issues, conclusions from a study, or comments, rather than recommendations. ACUS has adopted 20 statements.
