IB Chemistry IA Tutor — Expert Guidance for Your Internal Assessment
Your IB Chemistry Internal Assessment (IA) is a significant piece of work. It is worth 20% of your final IB Chemistry grade — for both Standard Level and Higher Level. That is a substantial portion of your overall score.
We offer IB Chemistry IA Tutor from top IB schools. We teach you. We guide you. We mentor you. You do the actual work. That is non-negotiable.
Our tutors are subject-matter experts. Many have worked as IB examiners for Chemistry. They know the official IB rubrics inside out — not just what they say, but how they are applied in practice. We do not paste the rubrics plainly on a page. Instead, we walk you through each of the four assessment criteria and show you exactly how to meet them in your own writing.
- Experienced IB teachers
- IB examiners
- One-to-one IB Chemistry IA tutor
- Helping students with Internal Assessments since 2017
Key Takeaway: We teach you how to approach your Chemistry IA. Your investigation remains your own work.

What Is the IB Chemistry IA?
The IB Chemistry IA is your own scientific investigation. It is your chance to explore a chemistry topic that genuinely interests you. You design an experiment or study, collect data, analyse it, and write a structured report of up to 3,000 words.
The IA is assessed using four official criteria:
Research Design – your question, background, and methodology
Data Analysis – how you record, process, and present your data
Conclusion – how you answer your question using your evidence
Evaluation – how you assess weaknesses and suggest realistic improvements
Each criterion is worth up to 6 marks, giving a total of 24 marks. Knowing the rubric is one thing. Knowing how to apply it in your own work is another. That is where our IB Chemistry IA tutor makes the difference.

Supporting Students Since 2017
We have been helping students with Internal Assessments since 2017.
The IA is not just another assignment. It contributes 20% of your total IB Chemistry mark. A well-executed IA can support your final grade. A poorly executed one can pull it down.
Why Is the IA So Important?
The IA is not just another assignment. It contributes 20% of your total IB Chemistry mark. A well-executed IA can support your final grade. A poorly executed one can pull it down.
But there is more to it than grades. The IA teaches you to think like a scientist. You learn to ask testable questions, control variables, handle uncertainties, and evaluate your own work honestly. These skills matter for university and beyond. The IB designed the IA to be a meaningful learning experience.
What Does Our IB Chemistry IA Tutor Cover?
We offer dedicated, one-on-one online tutoring for IB Chemistry, both SL and HL. Our IB Chemistry IA tuition covers every stage of the IA process, from the very first idea to the final submission.
Finding a Suitable Topic and Research Question With IB Chemistry IA Tutor
Coming up with an IA idea is often the hardest part. Your topic does not need to be completely original. But it should allow for a focused investigation. You can take an existing idea and modify it — change a variable, use a different material, or apply it to a new context.
We help you brainstorm. We show you how to turn a broad area of chemistry into a focused, investigable research question. Your question may clearly state your independent and dependent variables. Alternatively, it may involve two correlated variables, depending on the nature of your investigation. The IB allows both approaches, and we teach you how to frame either one correctly.
We also help you choose something you find genuinely interesting. When you are curious about your topic, it often shows in the quality of your work — not because “personal engagement” is a separate criterion, but because engaged students tend to think more deeply and write more thoughtfully.
Your topic can relate to a real-life example, but that is not a requirement. What matters is that your question is testable and leads to a coherent investigation.
Developing Your Research and Methodology
Once you have an idea, we help you develop it. We guide you in:
- Writing a clear, reproducible method
- Identifying and controlling your variables
- Including safety, ethical, and environmental considerations
- Justifying every experimental choice you make
We do not write your method for you. We teach you how to write one that an examiner could follow and repeat. That is a key part of the Research Design criterion.
We also help you analyse methodology from scratch. We walk through each step so you understand why you are doing what you are doing.
Strengthening Your Investigation
Your investigation should not feel like a random series of experiments. Examiners assess your work against the criteria. They want to see a cohesive investigation — one where every part connects to your research question.
We help you strengthen your IA through in-depth research. We show you how to use readily available materials like textbooks, journal articles, and reputable online sources to build your background knowledge and support your hypotheses.
Your introduction should be clear and concise — not overly descriptive. It should set up your question and explain the scientific context.
Illustrations such as graphs, tables, and diagrams should be clearly labelled and relevant. We teach you how to present these so your work is easy to follow. The official guidance does not require an illustration for every “experiment” — the IA is one scientific investigation — but appropriate visuals strengthen your report.
Data Analysis and Quantitative Work
Your research question should involve quantitative analysis. That means you need measurable numerical data. The IB also expects that quantitative data should be supported by qualitative observations where appropriate. We teach you how to integrate both effectively.
We help you:
- Record raw data in clear tables with correct units and uncertainties
- Process your data using averages, rates, graphs, and calibration curves
- Handle uncertainties properly — this is where many students lose marks
- Justify any data treatment, including decisions about outliers
Comparisons are important too. You may compare your results to literature values or to different conditions in your experiment. These comparisons must be clearly defined so the examiner can see exactly what you are comparing and why.
Writing a Strong Conclusion
Your conclusion must directly answer your research question. It should not be vague. Use your processed data and specific values to support your answer.
We teach you to compare your findings with accepted scientific literature and cite your sources properly. Reasonable conclusions are mandatory. A conclusion that does not answer the research question will not score well.
Your evaluation is equally important. Be honest about the weaknesses in your investigation. Suggest realistic, evidence-based improvements. Do not just list problems. Show the examiner that you understand the limitations of your own work.
Structure, Presentation, and Templates
We provide templates to help you design and format your IA. These are not fill-in-the-blank shortcuts. They are structural guides that show you the expected writing pattern for each section.
Using a template helps you understand the flow of a good IA. It keeps you organised and ensures you do not miss anything important. We explain why each section exists and what the examiner expects to find there.
Teacher’s Advice: A well-executed IA with depth and clarity is likely to score better than a long, unfocused one. A simpler investigation done thoroughly can score as well as — or better than — a complex one done poorly. Focus on doing your chosen investigation well.
How Our IB Chemistry IA Tutor Support You Throughout the Process
We do not just give you a few sessions and leave you alone. We offer ongoing external support throughout the IA process.
You can ask questions whenever you get stuck. We are here to help you work through problems — not to solve them for you.
We also evaluate your research as you go. We check that your method is competent, your data is sound, and your analysis is on track. We give constructive feedback so you can improve before your final submission.
We help you stay on track with clear planning and milestones. The IA is a long project. It is easy to fall behind. We break it down into manageable steps and help you keep moving forward.
Teacher’s Advice: Good overall planning helps you produce a strong IA. It keeps you organised and reduces stress. It also helps you present your work in a logical order, which makes it easier for the examiner to follow.
What Examiners Actually Assess
Examiners assess your IA against the four published criteria. They do not mark based on personal engagement, effort, or their personal inclination toward you. The process is standards-based.
They want to see:
- A clear, focused research question
- A reproducible method with justified choices
- Proper data handling and uncertainty analysis
- A conclusion that is justified by evidence
- A thoughtful evaluation of weaknesses and improvements
- Proper citations and academic integrity
Your IA must be understandable to the examiner. That means clear writing, logical flow, and proper structure. We teach you how to present your work clearly so the examiner can follow your thinking.
Teacher’s Advice: A well-executed IA with depth and clarity is likely to score better than a long, unfocused one. What matters is how well you meet each criterion. Focus on doing your chosen investigation well.
Understanding the IB Chemistry IA Assessment (Official Facts)
Before we go further, let us clarify what the IB actually requires. This information is based on the official IB Chemistry Guide (February 2023, updated November 2024) and IB Chemistry Examiner Instructions 2026.
| Feature | Official IB Specification |
|---|---|
| Official Name | Scientific Investigation |
| Weighting | 20% of the final grade |
| Total Marks | 24 marks |
| Time Allocation | 10 hours |
| Word Limit | Maximum 3,000 words |
| HL vs. SL | The IA requirements are the same for both levels |
Teacher’s Advice: The allocated time includes teacher explanation of requirements, student work, consultations, progress monitoring, and authenticity checks. The investigation involves the collection and analysis of quantitative data, supported by qualitative observations where appropriate.
The Four IB Assessment Areas (What You Are Actually Marked On)
Your IA is assessed across four areas. Each criterion is worth up to 6 marks, giving a total of 24 marks. We organize our tutoring around these exact areas.
Research Design
You are assessed on how clearly you communicate your research question, scientific context, and methodology. Your procedure must be detailed enough for someone else to reproduce it.
Data Analysis
You are assessed on how you record, process, and present your data. This includes the correct use of significant figures, appropriate representation of uncertainty, and suitable calculations.
Conclusion
You are assessed on whether you answer your research question using evidence from your data. A strong conclusion uses evidence from the investigation, applies relevant chemistry, and places the findings in an appropriate scientific context.
Evaluation
You are assessed on your critical reflection. You must explain the relative impact of specific methodological weaknesses and suggest realistic, justified improvements.
Teacher’s Advice: The investigation should not simply replicate a standard or well-known experiment. However, an existing practical or investigation can be adapted and extended to create a genuine investigation. We help you find a topic that is both original and feasible.
The Dos and Don’ts of an IB Chemistry IA
We cover all the important dos and don’ts.
Do:
- Choose a topic you are genuinely interested in
- Make sure your research question is testable and involves quantitative data
- Support your quantitative data with qualitative observations where appropriate
- Cite all sources properly
- Include uncertainties and justify your data treatment
- Write a clear, concise introduction
- Evaluate your work honestly
Don’t:
- Copy someone else’s IA or use a generic topic
- Delete outliers without justification
- Write a vague conclusion
- Ignore safety or ethical considerations
- Wait until the last minute
Teacher’s Advice: If your idea is lengthy but lacks focus, it may be better to simplify it. A clear, well-structured investigation is always preferable to a messy, overcomplicated one.
