1.1 Life Science: Biology Exam Facts

What changed in the biology Regents transition

The current New York biology Regents is the Regents Examination in Life Science: Biology. The older Regents Examination in Living Environment is still relevant during the transition because some students were taught under the older course and may still sit for that legacy exam, but NYSED's 2026 administration directions identify June 2026 as the last administration of Living Environment. For daily prep, the first job is not to memorize two separate labels. It is to confirm which exam your school scheduled and then study the format, evidence expectations, and course standards that match that exam.

Life Science: Biology is not just a renamed Living Environment test. NYSED's educator guide connects the current exam to the New York State P-12 Science Learning Standards, often shortened to NYSP12SLS. Those standards are three-dimensional: Science and Engineering Practices, Disciplinary Core Ideas, and Crosscutting Concepts are meant to work together. That is why the current exam gives you phenomena, data, models, and design problems instead of asking only isolated vocabulary recall.

Official format snapshot

The legacy Living Environment exam is different. The 2026 administration directions describe it as based on the Living Environment Core Curriculum, organized into five parts, and made up of 85 questions. That difference is a major Regents trap.

If you prepare for Life Science: Biology by practicing only old five-part Living Environment pacing, you may underpractice the current exam's cluster reading and constructed-response evidence habits. m. administration. Use that as a statewide schedule fact, but follow your school's reporting, admission, and make-up instructions.

Topic weighting tells you where breadth matters

The updated educator guide lists seven topic ranges: Structure and Function at 9-20%, Matter and Energy in Organisms and Ecosystems at 9-16%, Interdependent Relationships in Ecosystems at 14-27%, Inheritance and Variation of Traits at 14-27%, Natural Selection and Evolution at 14-24%, Earth's Systems at 2-9%, and Engineering, Technology, and Applications of Science at 2-11%. The ranges are wide because forms vary, but they show a clear pattern. Ecology, inheritance, and evolution can each be a large part of a form, while Earth-system and engineering ideas often appear by being woven into data, models, or solution design.

This also explains why a good study plan cannot be all flashcards. You need vocabulary, but you also need to use a graph to support a claim about carrying capacity, compare DNA evidence for common ancestry, interpret a feedback model, or evaluate an ecosystem solution against criteria and constraints. The current exam is designed so a biology fact often earns credit only when it is tied to the evidence in the cluster.

Investigations and admission to the exam

Life Science: Biology does not have a separate Regents performance test. Instead, students complete required Investigations during the course. NYSED identifies these as hands-on, three-dimensional tasks embedded in instruction. Successful completion is required for admission to the Life Science: Biology Regents, and the definition of successful completion is left to local discretion. The key scoring point is simple: investigation scores are not reported to the State and are not included in the student's final written-test score.

Approximately 15% of the written exam measures content related to performance expectations addressed by the Investigations. That does not mean the written exam asks you to recite a local lab packet. It means the skills and ideas from those experiences, such as feedback, gene variation, ecological solutions, models, variables, and evidence, can show up in new contexts.

Regents traps to avoid

• Do not read 65 as a percent correct. NYSED explains that 65 is a scale score, not the raw percentage of questions answered correctly.
• Do not mix the current and legacy structures. Life Science: Biology uses 9-11 clusters and 45-55 questions; Living Environment has its older five-part, 85-question structure.
• Do not ignore constructed response. About 40% of the current form is constructed response, and each item is still worth one credit.
• Do not treat investigations as extra credit. They are required for admission as locally determined, but they do not add points to the final Regents score.

A strong first-week plan is to make a one-page exam fact sheet, then practice one cluster at a time. For each cluster, record the phenomenon, the biological system, the data source, and the claim the questions are building toward. That habit matches the exam better than racing through disconnected facts.
