IB Internal Assessment Rubric and Grading Criteria

Throughout my years involved with the International Baccalaureate (IB) program, both as a student once and now a seasoned IB writer, I’ve gathered insights and strategies that have proven invaluable. Today, I’m eager to share this goldmine of knowledge with you, focusing on the cornerstone of your IB success: understanding and mastering the IB Internal Assessment Rubric and its grading criteria.

Breaking Down the IB Internal Assessment Rubric

Each IA rubric component, whether your research question, methodology, analysis, or conclusion, is crucial in your overall score. For instance, a well-defined research question sets the stage for a focused and coherent investigation. Similarly, a robust methodology underpins the credibility of your findings. Hence, understanding these components is crucial. Furthermore, integrating examples that align with each criterion can significantly bolster your IA.

The IA rubric varies by subject, but it generally assesses students on criteria such as research question formulation, investigation methodology, analysis and evaluation of results, and the overall presentation and structure of the work. Here’s an overview of the general criteria that can be applied across various subjects.

1. Criterion A. Focus and Method

Criterion A emphasizes the clarity, focus, and feasibility of the research question and the coherence and appropriateness of the methodology chosen to address it. This lays the foundation for a focused investigation.

2. Criterion B. Knowledge and Understanding

Criterion B assesses how well students demonstrate their knowledge and understanding of the topic relevant to the research question. It also evaluates the application of theoretical concepts and the analytical depth they bring to their research topic.

3. Criterion C. Critical Thinking

Critical Thinking, covered in Criterion C, assesses the student’s ability to analyze and evaluate sources, data, or information critically. It examines how well students can synthesize information to construct logical arguments or conclusions.

4. Criterion D. Presentation

The presentation, detailed in Criterion D, concerns how the research is organized and presented. It requires students to adhere to academic conventions, including proper citation and referencing techniques, ensuring the work is coherent and scholarly.

5. Criterion E. Engagement

Finally, Criterion E reflects on the student’s reflection on their research process, the challenges they faced, the skills they developed, and their engagement with the topic, indicating their motivation and interest.

Who Will Grade the IA in the IB?

In the IB Diploma Programme, the Internal Assessment is primarily marked by the student’s teacher within the school. This approach allows for a detailed and personal assessment of the student’s work, drawing on the teacher’s understanding of both the subject criteria and the student’s skills and efforts throughout the research process.

After the teacher assigns a grade to the IA, a sample of IAs from the school is sent to external IB examiners for moderation. This process ensures consistency and fairness in grading standards across schools and countries. Moderation may result in the teacher’s marks being adjusted upwards or downwards to align with the global standard set by the IB for that subject.

The dual grading system, which includes internal and external assessments, is designed to maintain the integrity and international standardization of the IB Diploma Programme. It ensures that students around the world are assessed against the same criteria. It supports a comprehensive assessment of students’ skills and knowledge, considering both their teachers’ detailed insights and the objective standards of the IB.

Grading Criteria for All Types of IB Internal Assessments

As someone deeply immersed in the International Baccalaureate for many years, I’ve had the opportunity to guide countless students through the rigorous path of completing their Internal Assessments. Drawing from my extensive experience, I’d like to share some insights into the grading criteria for all IAs across the IB curriculum. These reflections are grounded in the general IB criteria and my observed nuances.
