The IA is a research proposal. Treat it like one.

Break the task into four sections, make a clear methodological decision and justify your choices. The free pack below turns a large project into a sequence you can actually follow.

The four sections at a glance

The PsychExcel one-page overview allocates six marks to each section and keeps the full proposal under 2,200 words.

SectionMarksSuggested wordsMain job
Introduction6400 to 450Set out a real problem, identify who it affects, summarise two studies and state your aim.
Research Methodology6450 to 500Choose and justify the method, procedure and ethical decisions.
Data Collection6450 to 500Show the tool, justify its design and identify what could go wrong.
Discussion6600 to 660Discuss likely findings, possible change, your own bias and an additional method.

Use your official course guidance and teacher instructions alongside these learning resources.

Before choosing a topic

Three questions should have clear answers.

What is the problem?

Choose something that is genuinely going wrong for someone, not simply a topic you find interesting.

Who does it affect?

Define a specific group with features that matter to the problem.

What could change?

If you cannot name a policy, service, rule or practice that could change, the discussion becomes much harder.

Independent research writing

Structure first. Then strengthen the argument.

Although the Extended Essay is a different task from the IA, the same student feedback highlights the kind of support PsychExcel emphasises for research writing: structure, argument development and appropriate research choices.

“Her guidance helped me understand how to structure each section, develop my arguments and select suitable research papers. With her support, I became much more confident in my essay and ultimately achieved an A for my final EE grade!”
