CCEA A2 1 Comparative Government and Politics: a complete overview of the UK compared with the USA or the Republic of Ireland

CCEA A2 1, Comparative Government and Politics, is the first A2 unit of the CCEA A-Level Government and Politics course, set and marked by CCEA in Northern Ireland. This page is the index: below is a map of the unit, the assessment, and how to study each part.

What A2 1 covers

A2 1 is a comparative study of the United Kingdom against one of two comparators, chosen by the centre.

• Comparative approaches and the UK constitution. The purpose and methods of comparison, and the UK's uncodified, unentrenched constitution, which provides the baseline for both options.
• Option A: the UK and the USA. Comparing the two constitutions, Parliament and Congress, the Prime Minister and the President, the judiciaries, and the political process, framed by fusion versus separation of powers.
• Option B: the UK and the Republic of Ireland. Comparing the two constitutions, Parliament and the Oireachtas, the Prime Minister and the Taoiseach, the heads of state, the judiciaries, and the political process, framed by a shared parliamentary form over different foundations.

The central themes

Two themes run across whichever option is studied.

• Constitution shapes everything. The contrast between the UK's parliamentary sovereignty and the codified, entrenched constitutions of the USA and Ireland explains most of the other differences.
• Form versus foundation. Systems can share a form (for example a parliamentary executive) while differing fundamentally in their constitutional and electoral foundations.

Assessment structure

A2 1 is assessed by a written examination on the chosen comparative option.

• Shorter questions ask students to explain or analyse comparative features.
• Longer evaluation essays (to-what-extent questions) require a balanced, comparative argument and a substantiated judgement.

How to study A2 1

This unit rewards precise knowledge of both countries and disciplined comparison.

1. Master the UK baseline first. Comparison is impossible without secure knowledge of the UK system.
2. Learn paired points. For each institution, learn the position in both countries side by side.
3. Always compare, never just describe. Explicit, point-by-point comparison is the examined skill.
4. Explain the cause. Trace differences back to the constitution and electoral system.
5. Reach a judgement. Conclude with a substantiated verdict on the question set.
