Assess students' understanding of U.S. federalism by testing knowledge of the constitutional division of powers (enumerated, reserved, concurrent), key clauses and Supreme Court precedents that shape federal-state relations (e.g., Commerce Clause, Necessary and Proper, 10th Amendment), and the effects of federalism on policymaking in areas such as education, healthcare, and the environment; include brief case-study analysis and short-answer items that require explaining conflicts, cooperation mechanisms (grants, mandates, preemption), and contemporary policy examples.
