Which of the following is NOT a Cabinet-level position?

The High Commissioner of Education is not a Cabinet-level position in the United States. The Cabinet consists of the heads of the executive departments of the federal government, and these positions are typically referred to as "Secretaries" for departments like Agriculture, Defense, and Attorney General, which leads the Department of Justice.

A High Commissioner may hold a position in various contexts or jurisdictions, but in the U.S. federal government, there is no recognized Cabinet-level role with this title. This distinction is essential for understanding the structure of the U.S. government and the roles that operate at the executive level.
