US Constitution and Federalism
Codification, separation of powers, checks and balances, amendment, federal-state relations and comparison with the UK constitution and devolution.
How to study A-level Politics
Build durable knowledge of institutions, concepts and thinkers, then maintain a dated evidence file for elections, office-holders, cases, party positions and political events.
Core concepts
Concept 1
The US Constitution distributes power through federalism, separated institutions and checks and balances.
Exam cue: Name the constitutional provision or principle before using an example.
Concept 2
Formal amendment is difficult, so interpretation, political practice and institutional development also shape constitutional change.
Exam cue: Separate legal power from the political capacity to exercise it.
Concept 3
US federalism and UK devolution differ in constitutional entrenchment, sovereignty and the position of territorial units.
Exam cue: Make comparison explicit using one criterion on both systems.

Memory anchors
Codified Constitution
A codified constitution consolidates fundamental rules in an authoritative constitutional text.
Federalism
Federalism constitutionally divides power between national and state governments.
Separation of Powers
Separated institutions allocate legislative, executive and judicial functions to distinct branches.
Checks and Balances
Checks and balances allow branches to limit and influence one another.
Amendment
The formal US amendment process requires exceptional agreement across federal institutions and states.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
