AQA A-Level Geography skills and fieldwork: a complete overview of cartographic, statistical and enquiry skills and the NEA

What skills and fieldwork actually demand

Geographical skills are the practical backbone of AQA A-Level Geography. They are embedded across both written papers as AO3 and tested most fully in the geographical fieldwork investigation (the non-examined assessment). The examiners want you to calculate, apply and critically interpret maps, graphs, statistics and qualitative sources, and to plan, carry out and evaluate a fieldwork enquiry. This guide walks through the skill set and the investigation, then sets out how each is assessed. The matching dot-point page works through the detail with practice questions; this overview ties it together.

Cartographic and graphical skills

You must read and use a wide range of maps: Ordnance Survey maps (grid references, scale, relief, distance), GIS, and thematic maps such as choropleth (rates over areas), proportional-symbol (absolute quantities at points), isoline and flow-line maps. You must also construct and interpret graphs: line, bar, scatter and pie charts, plus specialist forms, logarithmic scales, triangular graphs (for three-part data), kite and radial diagrams, and dispersion graphs. The skill examined is not just drawing them but reading patterns and limitations (for example, why a choropleth implies false uniformity within each area).

Statistical skills

AQA expects confident handling of:

• Central tendency: mean, median and mode.
• Dispersion: range, interquartile range and standard deviation.
• Percentage change and proportion.
• Spearman's rank correlation coefficient, with significance testing against critical values.

The higher-order skill is interpretation: a statistic is meaningful only when tested for significance against the sample size, and correlation never proves causation.

The fieldwork enquiry process and sampling

Fieldwork follows the enquiry process: forming a question or hypothesis, designing a methodology (with justified sampling and a risk assessment), collecting primary and secondary data, presenting it appropriately, analysing it, drawing a conclusion and evaluating the whole enquiry. Choosing and justifying a sampling strategy is central:

• Random: unbiased but can cluster or miss areas.
• Systematic: even coverage and simple, but can miss periodic patterns.
• Stratified: ensures all relevant sub-groups are represented in a varied population.

The strategy must fit the aim and population, and the justification is credited.

The geographical fieldwork investigation (NEA)

The geographical fieldwork investigation is a student-devised, 3,000 to 4,000 word enquiry based on the student's own fieldwork, worth 60 marks (20 percent), marked by the school and moderated by AQA. It chiefly assesses AO3, with some AO1 and AO2. The marks concentrate on a tightly scoped question, a justified methodology, sound analysis, and above all a critical evaluation of reliability, validity, limitations and improvements. Students complete at least four days of fieldwork covering physical and human geography, which underpins it.

How skills are examined

A typical AQA profile for skills:

• Resource and data response. Reading maps, graphs, photographs and tables in both papers, and describing patterns precisely.
• Calculation. Working out percentages, measures of dispersion and Spearman's rank, with units and significance.
• Critical interpretation. Judging reliability, bias and the limits of data and methods.
• The investigation. Planning, carrying out and evaluating an independent enquiry.
