What this dot point is asking
Edexcel requires you to understand the independent investigation, the non-examined assessment: its nature and requirements, the independent fieldwork-based enquiry of 3000 to 4000 words using primary and secondary data, its structure through the enquiry process, and how it is assessed. It is worth 70 marks and 20 per cent of the A-Level. It is not examined in a written paper, so you only need to understand the process, not revise it for a timed exam.
The nature and requirements
The investigation must arise from the student's own fieldwork, of which Pearson requires a minimum of four days across the two years, spanning both physical and human geography. The question or hypothesis is devised by the student, although teachers may advise on feasibility and safety. The topic should be grounded in the specification, linking to a model, concept or debate from the physical or human content so that the enquiry is genuinely geographical rather than a generic survey.
The enquiry process
The report is structured around the geographical enquiry process, the same sequence used in fieldwork throughout the course.
- Purpose: a focused question or hypothesis, a clear aim, located context and links to geographical theory.
- Methods: a justified sampling strategy (random, systematic or stratified), primary data collection and relevant secondary data, with a risk assessment and consideration of reliability.
- Presentation: appropriate cartographic, graphical and statistical techniques to display the data.
- Analysis: interpretation of the data, including suitable statistical tests where relevant, with reference back to the theory.
- Conclusion: a clear answer to the question, supported by the evidence.
- Evaluation: a critical assessment of the reliability, accuracy and limitations of the methods and data, and how the enquiry could be improved.
Why the investigation matters
Although it is not sat as a written exam, the investigation develops exactly the skills the written papers reward: precise data handling, statistical reasoning, and the ability to connect evidence to theory and reach a justified, critically evaluated conclusion. The independence and evaluation it demands are the qualities that separate the highest grades across the whole qualification.
Examples in context
Example 1: a physical investigation. A student tests whether river velocity increases downstream on a local river, collecting primary data at several sites with a flow meter and secondary discharge data from a gauging station. They present the data with located graphs, analyse the relationship with a statistical test, conclude in relation to the Bradshaw model, and evaluate the reliability of their instruments and sampling. The enquiry links directly to the water cycle and drainage-basin theory.
Example 2: a human investigation. A student investigates whether environmental quality varies with deprivation across wards of a town, combining a primary environmental-quality survey with secondary Index of Multiple Deprivation data. They map and graph the results, test the correlation, conclude in relation to theories of inequality and place, and evaluate the subjectivity of their survey. This links to the diverse-places and regenerating-places content and shows synoptic thinking.
Try this
Q1. Explain why a risk assessment is a required part of the investigation. [4 marks]
- Cue. Fieldwork carries physical hazards; a risk assessment identifies them and sets controls, which is both a safety requirement and evidence of a well-planned, independent methodology.
Q2. State two ways the conclusion and evaluation differ in purpose. [2 marks]
- Cue. The conclusion answers the question from the evidence; the evaluation judges the reliability and limitations of the methods and data and suggests improvements.
Exam-style practice questions
Practice questions written in the style of Pearson Edexcel exam questions on this dot point, with worked answer explainers. The year tag is the paper they imitate, not the source.
Edexcel NEA (style)6 marksExplain why a focused, theory-linked research question is essential to a successful independent investigation.Show worked answer →
A question on enquiry design (AO3 with AO2). Explain that the research question or hypothesis sets the focus and scope for the whole investigation: it determines which data are relevant, which methods and sampling are appropriate, and what conclusion can be reached. A question that is too broad cannot be answered with the time and data available, while one that is too narrow or untestable yields little. A good question is focused, answerable and grounded in specification theory, such as a model, concept or debate from the physical or human content.
The strongest answers explain that a clear question makes the later stages, data collection, presentation, analysis and conclusion, coherent and defensible, and allows meaningful evaluation against a stated aim. Reward the explicit link between question design and the quality of the whole enquiry, ideally contrasting a workable question with an unworkable one.
Edexcel NEA (style)6 marksAssess the importance of the evaluation section in determining the quality of an independent investigation.Show worked answer →
A question on evaluation (AO3 with AO2). Explain that the evaluation assesses the reliability, accuracy and limitations of the methods and data, the validity of the conclusion, and how the investigation could be improved. For assessment, argue that evaluation is a major marked component because it demonstrates critical understanding: a confident conclusion that ignores its data's limitations is weaker than a measured conclusion that acknowledges them and suggests realistic improvements.
The strongest answers note that evaluation shows the student understands the whole enquiry process and can think like a geographer, tying the investigation back to its question and to wider geographical context. Reward a judgement that evaluation is essential to an honest, high-quality investigation rather than an optional add-on.
