What are the five criteria in the IB Mathematics AI IA rubric?<\/strong><\/p>\nThe five criteria are Criterion A (Presentation), Criterion B (Mathematical Communication), Criterion C (Personal Engagement), Criterion D (Reflection), and Criterion E (Use of Mathematics). Together they sum to 20 marks.<\/p>\n
How many marks is each criterion worth in the IB Mathematics AI IA?<\/strong><\/p>\nCriteria A, B, C, and D are each worth 3 marks. Criterion E is worth 6 marks. The total available score is 20 marks.<\/p>\n
What does the IBO mean by personal engagement in the IB Mathematics AI IA rubric?<\/strong><\/p>\nPersonal engagement refers to the degree to which a student demonstrates genuine intellectual curiosity and independent thinking throughout the exploration. It is not simply about choosing a personally interesting topic; it is about how a student responds to unexpected findings, asks follow-up questions, and makes creative or original analytical decisions during the investigation.<\/p>\n
What is the difference between mathematical communication and use of mathematics in the IB AI IA rubric?<\/strong><\/p>\nMathematical communication (Criterion B) assesses how you express your mathematics: Notation, labelling, consistency, and formatting. Use of mathematics (Criterion E) assesses what mathematics you apply and how correctly and deeply you apply it. A student can use sophisticated mathematics incorrectly and still score highly on Criterion B if the notation is clean and consistent, though they would score poorly on Criterion E.<\/p>\n
How is reflection assessed in the IB Mathematics AI IA?<\/strong><\/p>\nReflection is assessed on how critically and meaningfully a student evaluates their methods, results, and limitations. Top-band reflection appears throughout the paper, not only in a concluding section, and addresses the real-world implications of mathematical findings as well as the weaknesses of the chosen approaches.<\/p>\n
What does a top-scoring IB Mathematics AI IA look like under each rubric criterion?<\/strong><\/p>\nA top-scoring IA is coherent and concise (Criterion A), uses consistent and properly typeset notation throughout (Criterion B), demonstrates clear intellectual ownership of the investigation with responses to unexpected findings (Criterion C), contains critical evaluative commentary after each major mathematical milestone (Criterion D), and applies correct, course-level mathematics with demonstrated understanding rather than formulaic application (Criterion E).<\/p>\n
How does the IBO moderate IB Mathematics AI IA marks submitted by schools?<\/strong><\/p>\nThe IBO selects a sample of marked student work from each school and has trained examiners independently score that sample. If there is a consistent gap between the teacher’s scores and the examiner’s scores, the IBO applies a moderation adjustment to all student marks in that school. The adjustment can be positive or negative depending on the direction of the discrepancy.<\/p>\n
Conclusion<\/strong><\/p>\nAt Times Edu, our 1-on-1 tutoring approach means every student receives targeted feedback on each criterion before submitting a final draft. If you are working on your IB Mathematics AI IA and want an experienced consultant to review your topic selection, aim statement, or full draft against the official rubric, we invite you to book a personalised academic roadmap consultation. A single structured session can identify exactly where your marks are at risk and how to recover them before the submission deadline.<\/p>\n\n\n
