How much is the IB Chemistry IA worth?
In the Chemistry course first assessed in 2025, the scientific investigation is the same requirement at SL and HL: 10 hours, 20% of the final assessment and 24 available marks. Confirm that this is the guide used for the student's assessment session.
What is the IB Chemistry IA word limit?
The current Chemistry guide sets a maximum overall report length of 3,000 words and lists items that are excluded, including data tables, equations, calculations, citations, the bibliography and headers. Check the guide and school instructions before final submission.
What are the current IB Chemistry IA criteria?
The current SL and HL scientific investigation uses four criteria: Research design, Data analysis, Conclusion and Evaluation. Each criterion has six available marks, giving 24 marks in total, and the criteria are judged independently using a best-fit approach.
How many weaknesses should a Chemistry IA evaluation include?
The current public criterion does not prescribe a universal number. Select specific weaknesses or limitations that genuinely arise from the investigation, explain their relative impact, and connect each one to a realistic and relevant improvement.
Can a Chemistry IA evaluation say human error?
The phrase alone is generic and does not identify what happened or how it affected the investigation. Name the actual methodological issue, connect it to evidence in the data or procedure, explain its relative impact and propose an improvement that addresses that cause.
Can AI write a Chemistry IA evaluation?
Students must author and understand their assessed report. AI may be used only when the school and teacher permit the specific use, and permitted assistance or incorporated output must be acknowledged as required. It should not invent weaknesses, data or analysis or replace the student's judgement.
