Knowing the IB Chemistry IA rubric inside and out is crucial for achieving high scores on this internal assessment, as an experienced IB writer with a wealth of experience assisting students in succeeding will tell you. In my view, your final grade in IB Chemistry IA will depend on how well you adhere to the grading criteria. But have no fear; you will have accomplished half of your goal if you thoroughly grasp and carefully implement the Chemistry IA requirements.
What Are the Requirements for the Chemistry Internal Assessment?
To begin, what is the IB Chemistry Internal Assessment? Simply put, you lead a chemistry-related study as a student. But it’s not just because you’re interested. You must show that you are interested and fully understand chemistry ideas. The IB Chemistry IA rubric tells you how your IA will be graded by breaking it down into specific criteria that will help you focus your work in a structured way. I’ve seen that keeping the format clear and well-organized is essential for getting good grades on the IA.
One crucial part of your Chemistry IA is following specific rules and formalities. Your study has to be sound from a scientific point of view and also has to follow these structure rules:
- Make sure the work doesn’t go over 3000 words.
- At the beginning of your report, you need to clarify the subject of your study.
- At the start of the paper, put your IB candidate code or the codes of other group members if they apply.
- Also, you must write the number of words at the beginning of the work.
- The document’s text should all be aligned, and the data in tables should be in the middle of their cells.
- Last but not least, don’t forget to give a number to each page of your report.
Even though these rules may seem simple, I know from experience that even small mistakes can lower your score. Keeping everything neat and well-organized makes your work look more professional and keeps the examiner’s attention on your research instead of writing errors.
When I teach students, I first tell them that the IA is about how well you can think critically and explain what you found. The rubric keeps you on track so you don’t get too off track.
What Are the Grade Boundaries for IB Chemistry IA?
From what I’ve seen, knowing the grade boundaries for the IB Chemistry IA is essential for making attainable goals. There are several parts to the IB Chemistry IA grading criteria, and each part counts toward your total score. You should know what you must do to get a good grade at each grade level.
If you take the IA, you will usually get 24 points. Your final grade is based on your total score. Here’s a rough guide to the grade boundaries:
- 7 (excellent) – 21-24 points
- 6 (very good) – 17-20 points
- 5 (good) – 13-16 points
- 4 (satisfactory) – 9-12 points
- 3 (mediocre) – 5-8 points
- 2 (poor) – 1-4 points
- 1 (very poor) – 0 points
To get the best grade limit, you must closely examine every part of your IA: research design, data analysis, conclusion, and evaluation.

The Full Breakdown of IB Chemistry IA Rubric
A well-planned strategy is essential while dissecting the IB Chemistry IA grading criteria. As an experienced IB writer, I can tell you that you must carefully consider every part of the rubric. Let’s review all the requirements to ensure you have the best possibility of getting excellent scores.
Criterion A. Research Design (6 Points)
The research design is the most essential part of an IA since it lays the groundwork for the inquiry and establishes the overall tone. Starting with a specific research question that names the variables you’ll be studying and how they connect is an excellent place to start. To get all six points, you need to set the stage for the reader to comprehend your inquiry. It requires detailing the chemical components, outlining the chemical processes, and identifying essential terms.
Finding a reliable approach is, in my opinion, of the utmost importance. Explain your approach selection, provide a rundown of all the tools you’ll need, and provide a plan for how to carry out the study in a logical order. IB examiners place a premium on topics such as safety, ethics, and the environment, so cover these bases. Take the following example:
- Make sure to include both independent and dependent variables in your research question.
- Specifically, address the subject at hand by providing a relevant theoretical framework.
- Explain how you plan to measure these factors.
- Talk about the frequency, range, and accuracy of the measurements.
- Make sure to include safety and ethical concerns.
You should approach data from large-scale activities (like school experiments) as if you were conducting a database inquiry. If you don’t want to fail your IA, pay close attention to the data-filtering and sampling processes and make sure your approach is still reproducible in terms of clarity and detail.
Criterion B. Data Analysis (6 Points)
Data analysis is about making sense of all the data you’ve collected. I’ve seen students lose points in this area due to careless data processing or failure to account for uncertainty. Data selection, processing, and interpretation should all be part of your analysis. When looking for patterns or trends, I find that visual representations of data, such as graphs or tables, are the most useful.
To get all six points, no matter the Chemistry IA topic, accurately capture and analyze your data. Accurate and clear communication at each stage and appropriately annotated graphs and tables using units, decimal places, and significant numbers are required. In addition to ensuring your data is reliable and relevant to your research question, you must resolve any doubts. As an example, you need to:
- Clearly outline the steps used to capture and process the data.
- Please provide proof that uncertainty is being considered.
- Use figures, graphs, and tables to back up patterns and trends.
- Verify that there are no significant mistakes in the data processing.
In my view, if you take the time to present your facts correctly, examiners will see that you understand the research’s theoretical and practical components.

Criterion C. Conclusion (6 Points)
This part allows you to address your research question by synthesizing your results. In my opinion, it is crucial to back up your conclusion with evidence in addition to stating it. Compare recognized scientific literature, such as published articles or textbooks, and ensure that your conclusion aligns with the analysis. This comparison will more convincingly support your results. Your conclusion should include all six points:
- Respond directly to your research question while maintaining coherence with the facts.
- Make sure that your analysis is well-supported and justified.
- Reference relevant scientific works, such as journal articles and textbooks, in your analysis.
- Analyzed reference data, including any uncertainties.
In my view, if you provide a good comparison to other sources, examiners will see that you’re not only deriving results from your experiment but also putting them in a broader scientific perspective.
Criterion D. Evaluation (6 Points)
At long last, it’s time to put your inquiry to the test in the assessment. You should point out your technique’s good and bad parts and provide practical suggestions for fixing them here. From what I’ve seen, being as detailed as possible is critical. For example, if your measurements were imprecise, discuss how it affected your findings and suggest how to fix it. Find and discuss your investigation’s strengths if you want your assessment to get full marks:
- Draw attention to certain flaws in the methodology.
- Give an account of how these flaws impacted your ability to regulate variables and the accuracy of your data.
- Provide practical solutions to these issues.
In my view, a robust method of displaying critical thinking is the assessment, which is often disregarded. You demonstrate your comprehension of the intricacies of scientific research by identifying areas that might be improved in your inquiry.
What Are the Common Mistakes to Avoid in Chemistry IA?
Based on my observations, a handful of common errors students tend to make in their IB Chemistry IA may result in significant mark deductions. To improve your score, familiarize yourself with these typical mistakes and find ways to prevent them.
Students failing to address the IB Chemistry IA grading criteria adequately is a significant problem I have seen. Focusing on the science is essential, but so is ensuring you follow the rubric’s requirements. Other typical blunders to avoid include:
- Making the process too complicated. In many cases, less is more. A simple approach with good data is preferable to a complicated one with lousy execution.
- Data gathering is inadequate. If you don’t get enough raw data or don’t consider measurement uncertainties, your analysis can be compromised.
- Forgetting to assess the outcomes. Always evaluate your results critically and note any restrictions. If you skip this, your IA will seem unfinished.
- Report that is not well organized. It could be tough to follow your IA if you don’t number the pages, include your candidate code, or display the facts clearly in tables.
Finally, remember that first impressions are lasting impressions. It doesn’t matter how good your content is if your IA is a disaster.
