Administrative law judge

An administrative law judge (ALJ) in the United States is a judge and trier of fact who both presides over trials and adjudicates the claims or disputes (in other words, ALJ-controlled proceedings are bench trials) involving administrative law.

ALJs can administer oaths, take testimony, rule on questions of evidence, and make factual and legal determinations. And depending upon the agency's jurisdiction, proceedings may have complex multi-party adjudication, as is the case with the Federal Energy Regulatory Commission, or simplified and less formal procedures, as is the case with the Social Security Administration.

Federal appointment and tenure

The Administrative Procedure Act of 1946 (APA) requires that federal ALJs be appointed based on scores achieved in a comprehensive testing procedure, including a four-hour written examination and an oral examination before a panel that includes an Office of Personnel Management representative, an American Bar Association representative, and a sitting federal ALJ. Federal ALJs are the only merit-based judicial corps in the United States.
