About the HI Biology I EOC Exam
The Hawaiʻi Biology I End-of-Course Exam is the required statewide high school science assessment for students enrolled in Biology I under ESSA. It evaluates NGSS-based biology proficiency and is administered online near the end of the course. OpenExamPrep free practice uses English-language four-option MCQs as a study aid for NGSS biology knowledge and task decisions. It is not an official HIDOE form, not a full simulation of phenomena-based clusters or technology-enhanced tasks, and not a substitute for Biology I coursework or the secure EOC exam.
Exam sponsor: Hawaiʻi State Department of Education (HIDOE); EOC/science assessment systems. The requirements and fees below concern the certification or admission exam, separate from our free practice resources.
