IB Biology Higher Level (HL)

IB Biology HL is a two-year course that is designed to be the equivalent of a two-semester college introductory biology course. The goals of IB Biology HL are to help students develop a conceptual framework for modern biology and an appreciation of science as a process. Students will learn about biology in an internationally relevant context. Through hands-on experiences, students will develop the skills of a scientist.


A student’s IB score for this course is based on three external assessments and one internal assessment. The external assessments are written exams comprised of multiple-choice and free-response questions; these tests are taken at the end of the second year. The internal assessment requires each student to design their own experiment related to biology concepts and report their results and conclusions in a report similar to a paper published in a scientific journal.


Prerequisite: Proficiency in Chemistry or Chemistry Honors with Teacher Recommendation
