During the second year of the IB Biology HL class, students have the opportunity to research, design, perform, and write up their own investigation. This project is known as an internal assessment (IA). Students will spend 10 hours doing this investigation which will provide 20% of the overall assessment for the IB biology score (the IB score, not the class grade).
There is a large variety and range of possible investigations; each student must complete an investigation that is unique and adequately different from those of other students in the course. Students can choose from:
The Internal Assessment is assessed (that means ‘graded’) using very strict IB criteria. All IB science teachers world-wide must use the same criteria and apply them in the same way—quite a challenge!! To ensure that everyone is following the rules and applying the criteria correctly, schools must send samples of graded student lab reports to IB for monitoring. If a teacher is being too hard or too soft, that teacher’s marks which were awarded to students will be adjusted accordingly.
The IB Biology Internal Assessment is graded using five IB Internal Assessment Criteria. A maximum score of 24 points* is possible, awarded for the following five criteria:
