What Marksy checks for each SEHS IA 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 A: Research design

6 marks
  • The research question is focused and placed in a specific scientific context.
  • Method choices (variables, controls, range, repeats, data sufficiency) are explained, not just listed.
  • The procedure has enough detail for another student to reproduce it.

Criterion B: Data analysis

6 marks
  • Raw and processed data are traceable, with units and uncertainties.
  • Calculations, graphs, and any statistics are correct and fit the research question.
  • Uncertainties are propagated or discussed where they matter.

Criterion C: Conclusion

6 marks
  • The answer to the research question is explicit and backed by your processed data.
  • The claim is no stronger than the evidence allows.
  • The result is compared with published values, theory, or other studies.
  • Explain what the findings could mean for health or performance.

Criterion D: Evaluation

6 marks
  • Weaknesses are specific to this investigation, not generic.
  • The report explains how much each weakness affected the results.
  • Improvements are realistic and target the weaknesses you identified.
