Welcome to the world of Chemistry Internal Assessment (IA) drafting! As the International Baccalaureate (IB) curriculum evolves, so do the requirements for IB Chemistry. In this blog post, we will provide valuable tips to help students prepare and write their Chemistry IA drafts, along with a key note on the changes introduced to the Internal Assessment in the 2023 IB Chemistry Syllabus.

  1. Understanding the 2023 IB Chemistry Syllabus Changes:

The new IB Chemistry syllabus emphasizes a holistic approach, focusing on both theoretical knowledge and practical application. It encourages students to integrate various aspects of chemistry, promoting a deeper understanding of the subject.The main changes to the new syllabus include:

Renaming and Criteria Adjustment:

  • The new IB Chemistry syllabus redefines the internal assessment research as “The scientific investigation,” replacing its former title, “The individual scientific investigation” from the 2014 Guide.
  • The assessment now focuses on four equal criteria (Research design, Data analysis, Conclusion, and Evaluation), each carrying 6 marks, totaling 24 raw marks, which are then scaled to account for the 20% internal assessment weighting.

2. Emphasis on Advanced Cognitive Skills:

  • The restructuring of criteria, with half the marks allocated to Conclusion and Evaluation, highlights a heightened emphasis on advanced cognitive skills.
  • Enhanced Experimentation: The revised IA places a higher emphasis on experimental design and execution. Students are encouraged to delve into more comprehensive and sophisticated experiments, fostering critical thinking and analytical skills.
  • Interdisciplinary Connections: Explore connections between chemistry and other disciplines. Highlighting these connections can significantly enrich your IA, demonstrating a broader understanding of how chemistry interfaces with fields like biology, environmental science, or even technology.
  • Data Analysis and Evaluation: There’s a renewed focus on critical data analysis and evaluation. Demonstrate your ability to interpret experimental results accurately and draw meaningful conclusions. Incorporating statistical analysis tools and techniques could elevate the quality of your IA.

3. Time Allocation and Collaboration:

  • The latest guidelines maintain the 10-hour time allocation for the research project.
  • A more flexible approach to collaboration is introduced, allowing students to work in small groups, with one or two peers. Collaboration is encouraged, but each student must maintain a unique research question. Methodologies can be shared, but variables and data must remain distinct for individuality.

4. Changes in Written Report Structure:

  • The written report undergoes structural changes with a maximum word count set at 3,000 words.
  • The 2023 guide provides specific instructions on what constitutes a word, deviating from the 2014 Guide, which used a page range of 6-12 pages. The new word count guideline offers a clearer framework for students to structure their reports.

Tips on Writing Your Chemistry Internal Assessment Draft:

Now that we understand the changes in the 2023 IB Chemistry Syllabus, let’s delve into practical tips to help students excel in their IA drafts.

1. Choose Your Topic Wisely:

  • Select a topic that aligns with your interests and the curriculum.
  • Ensure the topic allows for a feasible and meaningful investigation.

2. Clearly Define Your Research Question:

  • Craft a concise and focused research question that can be effectively addressed within the scope of the IA.

3. Conduct Thorough Background Research:

  • Familiarize yourself with existing literature related to your topic.
  • Highlight key concepts, theories, and methodologies that will inform your investigation.

4. Demonstrate Experimental and Analytical Skills:

  • Design and carry out experiments with precision, using accurate scientific terminology and specific details to convey.
  • Approach with an analytical mindset, breaking down complex ideas into smaller components and providing logical explanations.
  • Utilize advanced analytical techniques when applicable.

5. Incorporate Quantitative and Qualitative Data:

  • Balance your IA by including both quantitative data and qualitative observations.
  • Use appropriate units, measurements, and scientific language.

6. Interpretation of Results:

  • Comment on the extent to which the data supports the hypothesis.
  • Discuss the strengths and limitations of your investigation.
  • Provide suggestions for improvement.

7. Be Organized and Structured

  • Writing should be organized and structured.
  • Present information in a logical sequence, following a clear outline or framework. 
  • Ensure that the IA is clear, concise and easy to follow.  

8. Adhere to the Assessment Criteria:

  • Refer to the revised assessment criteria to ensure your IA meets the expectations outlined in the updated syllabus.
  • Pay attention to changes in emphasis and any new requirements.

9. Seek Guidance and Feedback:

  • Regularly communicate with your teacher, seeking guidance and feedback to refine and enhance your draft.
  • Proofreading and using the mark scheme to evaluate and improve the draft are essential. 
  • Seeking external grading help like a Chemistry IA tuition can be helpful.


In conclusion, navigating the changes in the 2023 IB Chemistry Syllabus is crucial for successfully writing your Internal Assessment. By choosing a well-defined topic, conducting thorough research, and addressing the reflective statement, you can showcase your skills in line with the updated assessment criteria. Keep these tips in mind, and you’ll be well on your way to excelling in your Chemistry IA. Good luck!
