CCEA AS 1 Historical Investigations and Interpretations is one of the two written units of the AS-Level course. You study one option from a choice of twentieth-century investigations and are tested on both source evaluation and analytical essay writing. This overview maps the most popular options and how to approach the unit.
The popular options
The unit offers several options; three are especially widely taught.
- Germany 1919 to 1945
- The collapse of the Weimar Republic, the rise of the Nazi Party, the consolidation of dictatorship after 1933, the Nazi state in peace and war, and the persecution that led to the Holocaust. The unifying theme is how a democracy gave way to a total dictatorship.
- Russia 1914 to 1941
- The strains of the First World War on Tsarism, the revolutions of 1917, Lenin and the civil war, and Stalin's transformation of the USSR through collectivisation, the Five-Year Plans and the Terror. The unifying theme is revolution and the building of a one-party state.
- The USA 1917 to 1945
- Entry into the First World War and the retreat into isolationism, the 1920s boom and its social tensions, the Wall Street Crash and Great Depression, Roosevelt's New Deal, and the impact of the Second World War. The unifying theme is boom, bust and the growth of federal power.
How AS 1 is assessed
AS 1 is a written paper on your chosen option, combining source and essay tasks.
- The source-based question. Assess the value and reliability of primary sources to a historian studying a named issue, using provenance, content and tone, and your own knowledge.
- The essays. Build a sustained, analytical argument that answers the question and reaches a substantiated judgement.
How to study AS 1
This unit rewards precise knowledge and disciplined exam technique.
- Learn the option as causes and turning points. Track why change happened, not just what happened.
- Master precise detail. Names, dates and events are the evidence your essays and source answers need.
- Drill the source question. Work through provenance, content and tone, and judge value against context.
- Practise essays under time. A clear thesis, analytical paragraphs and a substantiated judgement win marks.
- Use CCEA past papers. Question style and mark schemes are board-specific.
