### MCAS STE Biology: Using Mathematics in Science - Objectives

The MCAS STE Biology is exam assesses high school students' level of academic understanding of biology as set by the Massachusetts Curriculum Framework standards. The MCAS STE Biology exam is scored based on five content areas including biochemistry and cell biology, genetics, anatomy and physiology, ecology, evolution and biodiversity. Because mathematical equations are essential in understanding all scientific data, questions related to using math in science could be part of any or all of these content areas.

The MCAS STE Biology exam is comprised of 40 multiple-choice questions and five open-ended responses. A scaled score of 220 or higher is required on one of the four STE exams in order to qualify for graduation.
