Economic Skills You Need To Demonstrate (DP IB Economics): Revision Note
Introduction to the assessment objectives
IB Economics assesses four broad skills, known as assessment objectives (AOs)
These skills are signalled in exam questions through command terms (such as 'define', 'analyse', 'evaluate' or 'recommend')
Understanding how these skills work together will help you interpret questions accurately and avoid writing the wrong type of answer
AO1: Knowledge and understanding
AO1 is about showing that you know and understand Economics
In exams, this means you should be able to:
define economic terms accurately
explain economic concepts and theories clearly
use correct economic terminology throughout your answer
AO1 is most visible in short questions (such as definitions or brief explanations), but it underpins all answers
Without accurate knowledge, examiners cannot reward analysis or evaluation
Examiner Tips and Tricks
In practice, vague definitions or incorrect terminology immediately limit your marks, even in longer answers
Typical command terms linked to AO1
Define
List
State
Describe
Outline
AO2: Application and analysis
AO2 focuses on your ability to use economics in context
This means you must be able to:
apply economic theory to real-world situations
use information from texts, tables, diagrams or data
explain how economic concepts operate in the specific situation described
AO2 is especially important in Paper 2 and Paper 3, where answers must be clearly linked to the stimulus material provided
Correct theory that is not applied to the context cannot score highly
Examiner Tips and Tricks
In practice, simply explaining theory is not enough - you must show how it fits the situation in the question
Typical command terms linked to AO2
Explain
Analyse
Comment on
Distinguish
Apply
AO3: Synthesis and evaluation
AO3 is about thinking like an economist: weighing up arguments and reaching justified conclusions
This involves:
building clear economic arguments
using theory and evidence together
considering different perspectives or outcomes
making balanced judgments
AO3 is essential in higher-mark questions, such as Paper 1 (15 marks), Paper 2 part (g), and the Paper 3 policy recommendation
Examiner Tips and Tricks
In practice, evaluation is not opinion. It must be based on economic reasoning, evidence, and context
Typical command terms linked to AO3
Discuss
Evaluate
Examine
To what extent
Justify
Recommend
AO4: Use and application of skills
AO4 refers to the technical skills used in Economics
This includes your ability to:
draw and label diagrams accurately
carry out calculations correctly
interpret numerical and graphical data
organise your answers clearly and logically
AO4 is particularly important in Paper 2 and Paper 3, but diagram skills and clear written structure are relevant across all papers
Examiner Tips and Tricks
In practice, technical mistakes (missing labels, wrong units, incorrect rounding) often cost easy marks
Typical command terms linked to AO4
Calculate
Draw
Sketch
Label
Plot
Derive
Determine
Show
How these skills work together in exams
Most IB Economics questions assess more than one skill at the same time
For example, a 15-mark question may require AO1 (knowledge), AO2 (application), AO3 (evaluation), and AO4 (diagrams)
Command terms tell you which skill to prioritise, but strong answers usually combine several skills effectively
Understanding this skills framework will help you decide:
how much to write
whether to include diagrams or calculations
and how much evaluation is required
Command terms (how questions signal what to do)
Command terms are classified according to the AO levels
Cognitive demand progresses from AO1 → AO3, while AO4 command terms are skills-based (for example calculations, diagrams, and data handling)
How to use this in exams
Most exam questions assess more than one AO at the same time
Command terms indicate the dominant skill being targeted, so students should use them to decide how much explanation, data use, diagram work, and evaluation is required
AO1 questions require precision and accuracy (definitions, brief descriptions).
AO2 questions require you to apply theory to a context or stimulus AND develop clear analytical links
AO3 questions require you to build an argument AND make balanced judgments (evaluation must be supported by analysis)
AO4 questions require technical skills (accurate diagrams, correct calculations, and correct interpretation/handling of data)
