Assessment

Internal Assessment Practical work in integrated throughout each topic in the programme of study. Here the students will have the opportunity to develop a detailed and extensive Practical skills portfolio. HL students are expected to carry out 60 hours of practical work throughout the course. The internal assessment is integral to this, providing students an opportunity to pursue their personal interests. The work is marked on the following criteria; Research design, Data analysis, Conclusion, Evaluation. IB students are required to complete a “Collaborative sciences project”, during which they collaborate with other scientists from the full range of subjects. Throughout the programme, their personal skills, ability to work independently and awareness of wider ethical aspects of the subject are assessed. External Assessment The assessment structure is almost identical for SL and HL and is broken down as follows: 20% from Internal Assessment of practical work (externally moderated) 80% from two written examinations: •Paper 1: o1A multiple choice questions (HL 40 marks) o1B Data based and experimental work (HL 35 marks) •Paper 2: Structured and extended response questions. (HL 90 marks)
