What Marksy checks for each Psychology EE criterion
You get a mark for each IB assessment criterion below. The points under each one are what Marksy looks for in your draft. See the mark bands
Criterion B: Knowledge and understanding
6 marksShow subject knowledge through relevant sources, concepts and accurate terminology.
Criterion C: Analysis and line of argument
6 marksAnalyse the research and connect the question, findings and conclusions.
Criterion D: Discussion and evaluation
8 marksWeigh the findings and assess the strengths and limits of the research.
Criterion E: Reflection
4 marks- This criterion uses the reflective statement on the RPF, rather than the essay itself.
Where Psychology EEs usually lose marks
Marksy flags these in your draft and links each one to the sentences it is about.
- Running your own studyA Psychology EE must be based on published research. Your own survey, experiment or interviews aren't allowed, so the essay is a review of other people's studies.Criterion A
- A key term that isn't defined"Performance" or "stress" can mean many things. Say how your key term is measured in the studies you use, and keep that meaning the whole way through.Criterion A
- Too much background on approachesExplaining every assumption of CBT or the biological approach eats your words. The guide says a short outline is enough. Spend the space on the studies.Criterion B
- Studies summarised one by oneA study-by-study list is description. Group studies by what they show, link them to theory, and build toward your answer.Criterion C
- Studies taken at face valueSay how each key study's sample, method and setting affect how far you can trust it, and how far it applies to the people in your question.Criterion D
- Only evidence that agrees with youThe guide's perfectionism example looks for studies that support and challenge the idea. Give the challenging evidence real weight before you conclude.Criterion D
Before you upload
- Cite each study with its authors and year, so every claim can be traced to a source.
- Say in your introduction how you define your key term.
- Leave out any data you collected yourself. A Psychology EE uses published studies only.

Questions before you upload

No. A Psychology EE is based on published research only, so collecting your own data isn't allowed. Peer-reviewed studies are the core of the essay.
The IA is a proposal for a study, with a data collection tool you design, marked by your teacher. The EE is a 4,000-word review of published research, marked by an IB examiner.
You won't need consent forms. Ethics can still matter in your evaluation: if a study you rely on used deception or a vulnerable group, say how that affects what it can tell you.
