1789-1801, 1802-1869
- Circuit courts organized by judicial district (e.g. U.S. Circuit Court for the District of Massachusetts) and assigned to judicial circuits

1801-1802
Circuit courts organized by judicial circuit (e.g. U.S. Circuit Court for the First Circuit)
- Three circuit judgeships for each of the First through Fifth Circuits; Sixth Circuit held by one circuit judge and district judges of Tennessee and Kentucky
1869-1911
- Circuit courts organized by judicial district and assigned to judicial circuits
- Circuit judgeships established for each circuit; circuit courts held by justices of the Supreme Court of the United States, circuit judges, district judges, or combinations thereof.
