Which court is described as the federal appellate level immediately below the Supreme Court?

The Circuit Court of Appeals is indeed the federal appellate court level immediately below the Supreme Court. In the federal judiciary system, the Circuit Courts of Appeals serve as the first level of appeal for decisions made by District Courts. These courts review cases to determine if there were any legal errors made during the trial that could impact the verdict or the application of law.

Once cases have been decided in the Circuit Courts, the next step for appeal is to the Supreme Court of the United States, which has the discretion to choose which cases to hear. The structure supports a hierarchical system of justice, where appeals from lower courts may be addressed with a mechanism in place to ensure that a higher court can evaluate the determinations made by the Circuit Courts.

Other options like District Courts primarily handle trial-level cases rather than appeals, and the State Supreme Court pertains to state-level judicial systems rather than federal appellate jurisdiction. The mention of a "Supreme Court Division" does not align with the established court structure within the United States federal system. Thus, the designation of the Circuit Court of Appeals as the federal appellate court directly under the Supreme Court is accurate and reflects the correct understanding of the hierarchy within the federal judicial framework.
