The Historical Investigation (Component 3) is a non-exam assessment (NEA) requiring students to independently research and write an extended essay of 3500-4500 words on a topic of their choice. The investigation must be placed in the context of approximately 100 years, must not duplicate content from Components 1 and 2, and must ensure that all three components together cover a chronological range of at least 200 years. It requires the evaluation of primary sources and the analysis of differing historical interpretations.
The Historical Investigation (Component 3) is a non-exam assessment (NEA) that forms a compulsory part of the AQA A-Level History qualification, accounting for 20% of the total A-Level marks. This personal study requires you to independently research and write a 3,000–4,500 word essay on a historical question of your own devising, focusing on a period of at least 100 years. The investigation must be based on primary and secondary sources, and you are expected to demonstrate skills of analysis, evaluation, and argument. This component is designed to assess your ability to think like a historian, engaging with historiography and constructing a sustained, evidence-based argument.
The NEA is unique because it allows you to pursue a topic that genuinely interests you, whether it's the causes of the English Civil War, the impact of the Industrial Revolution on working-class women, or the debate over the origins of the Cold War. However, this freedom comes with responsibility: you must frame a focused question that is manageable within the word limit and for which sufficient sources exist. The investigation is marked on four objectives: AO1 (demonstrate knowledge and understanding), AO2 (analyse and evaluate sources), AO3 (analyse and evaluate interpretations), and AO4 (communicate substantiated judgements). Success requires careful planning, critical engagement with historians' views, and a clear, logical structure.
This component fits into the wider A-Level by complementing the examined units (Breadth Study and Depth Study). While those units test your ability to write under timed conditions and cover prescribed content, the NEA tests your capacity for independent research and extended writing. It mirrors the skills required at university level, making it excellent preparation for higher education. Many students find the NEA the most rewarding part of the course, as it allows them to become a 'mini-expert' on their chosen topic. However, it also demands strong time management and self-discipline, as the work is done largely outside of class time.
