IB Chemistry IA rubric/Chemistry IA Criteria 2025
The Internal Assessment (IA) for IB Chemistry, effective from the May 2025 examination session, is evaluated based on four primary criteria, each contributing equally to the overall score. Each Chemistry IA Criteria is scored out of 6 marks, totaling a maximum of 24 marks, which constitutes 20% of the final grade.
The demanding curriculum pushes students to engage with various fields, while the Theory of Knowledge (TOK) course promotes critical analysis. The Extended Essay (EE) sharpens research and writing skills, reflecting the standards of higher education. Moreover, the Creativity, Activity, and Service (CAS) component encourages holistic personal growth. IB alumni emerge well-equipped for university life, having developed crucial skills such as time management, adaptability, and problem-solving, all essential for achieving success in higher education and future endeavors.
