Direct Answer: Living Environment Ended, but the Lab Rule Did Not
The Regents Examination in Living Environment is no longer administered. NYSED gave the final legacy exam on June 18, 2026. If your school is preparing you for a biology Regents now, the current test is the Regents Examination in Life Science: Biology.
That distinction changes which practical work you must complete:
| If you are checking... | What controlled admission |
|---|---|
| The legacy Living Environment exam through June 18, 2026 | 1,200 laboratory minutes with satisfactory reports plus four required Living Environment laboratory activities |
| The current Life Science: Biology exam | The 1,200-minute science laboratory requirement with satisfactory reports plus three required Life Science: Biology Investigations |
The old four labs remain useful for understanding archived Living Environment scores, reviewing old Part D questions, and strengthening biology concepts. They do not replace the three Investigations required for admission to the current Life Science: Biology exam.
The 1,200-Minute Requirement Still Matters
The NYSED Science FAQ says a student must complete 1,200 minutes of laboratory experiences with satisfactory documented laboratory reports to qualify for a science Regents. That equals 20 hours. The laboratory time is in addition to the classroom instruction required for the science course.
Current policy permits any combination of hands-on and simulated laboratory experiences to satisfy the 1,200 minutes. Older NYSED documents sometimes say "hands-on" because they predate the January 2023 regulation change; the current Science FAQ controls.
The FAQ also answers practical record questions that many prep pages omit:
- The requirement must be met before admission to the Regents, although a school may set a local target date for completion and submission.
- Once the laboratory requirement is met for a specific science Regents exam, it does not expire for a later administration of that same exam.
- Laboratory minutes from a sending school may count for a transfer student. A district may request an attestation stating how many successful minutes were completed.
- Passing the course itself is not the admission test. NYSED describes circumstances in which a student who did not pass the course may still sit after completing the course of study and the laboratory requirement.
- For the legacy required activities, satisfactory reports were to be kept on file for at least six months after the examination.
If your record is uncertain, do not estimate your own minutes. Ask your teacher, counselor, or test coordinator to confirm in writing:
- the exact Regents title you are scheduled to take;
- your recorded laboratory minutes;
- whether the associated reports are satisfactory and on file;
- whether all required Investigations for the current course are complete; and
- whether transfer-school minutes need an attestation.
The Four Required Legacy Living Environment Labs
NYSED's Laboratory Activities for Living Environment Part D required every legacy candidate to complete these activities before the exam:
| NYSED number | Required lab | Central idea | High-value review move |
|---|---|---|---|
| #1 | Relationships and Biodiversity | Evolutionary relatedness, biodiversity, structural and molecular evidence | Compare test results and cite the specific similarity that supports the closest relationship |
| #2 | Making Connections | Homeostasis, experimental design, pulse, fatigue, variables and graphing | Identify the changed and measured variables, then support a conclusion with the data |
| #3 | The Beaks of Finches | Variation, competition, natural selection and population change | Explain how feeding success affects survival and reproduction without saying an individual evolves |
| #5 | Diffusion Through a Membrane | Diffusion, indicators, selective permeability and osmosis | Track which molecules cross, predict indicator changes, and explain movement down concentration gradients |
The numbering is not a typo. NYSED's Part D memo listed Activities #1, #2, #3, and #5 and explained that Activity #4 was still under development and had not been released. No required Lab #4 entered the legacy program before the exam ended.
The four required activities could count toward the 1,200-minute total, but completing only these packets did not automatically prove 1,200 minutes. Schools still had to document the total laboratory time and satisfactory reports.
What the Final Part D Actually Counted
The June 2026 administration directions describe the final Living Environment form precisely:
| Part | Question style | Raw credits |
|---|---|---|
| A | Multiple choice | 30 |
| B-1 | Multiple choice | 13 |
| B-2 | Multiple choice and constructed response | 12 |
| C | Constructed response | 17 |
| D | Multiple choice and constructed response based on required labs | 13 |
| Total | Five scored parts | 85 |
NYSED's Part D materials state that a form tested at least three of the four required laboratory activities. That did not mean students could safely skip one: the tested combination was not announced in advance.
Part D was not a separate hands-on practical performed on exam day. It was a written 13-credit section using multiple-choice and constructed-response questions based on the required laboratory experiences and laboratory skills. Several competing pages call it a "lab practical," which can mislead students about the administration format.
The Final Passing-Score Math
A Regents score of 65 is a scale score, not 65% raw correct. NYSED issued a different raw-to-scale conversion chart for each administration.
On the official June 2026 Living Environment conversion chart, a raw score of 40 out of 85 converted to 65. A raw 39 converted to 64. The January 2026 and earlier charts used different mappings, so "40 raw always passes" is also wrong.
This makes every raw credit useful near the boundary, but it does not justify promising that a particular Part D score guarantees a pass. A student's final result depended on the total raw score across all five parts and that administration's conversion chart.
How to Review Each Legacy Lab Accurately
Relationships and Biodiversity
Focus on the chain from evidence to evolutionary inference. Structural similarities, DNA information, amino-acid evidence, chromatography patterns, and indicator results can support a conclusion about relatedness. The strongest answer names the observed match and explains why greater similarity supports a closer relationship; it does not merely name a species.
Making Connections
Treat this as experimental-design and homeostasis practice. Identify the hypothesis, independent variable, dependent variable, comparison or control, constants, repeated trials, and measured trend. Pulse rate and squeezes before fatigue are outcomes only when the particular investigation measures them. Always follow the variables defined in the prompt.
The Beaks of Finches
The tools represent different beak variations, and the available objects represent food resources. Feeding success can affect survival and reproduction. The population changes over generations when a heritable variation becomes more or less common; an individual bird does not reshape its inherited beak because it "needs" to adapt.
Diffusion Through a Membrane
The model membrane is selectively permeable. Small molecules such as iodine and glucose can cross it, while the much larger starch molecules remain inside the model cell. Iodine indicates starch with a blue-black color, and Benedict's solution is used to test for reducing sugars such as glucose. Explain movement using particle size and concentration gradients rather than saying the membrane "chooses" molecules.
What Replaced Part D for Current Students
Life Science: Biology has no legacy Part D. NYSED replaced the four Living Environment activities with these three course Investigations:
- Structure and Function: Balancing Act – Exploring Feedback and Homeostasis
- Inheritance and Variation of Traits: Unraveling the Mystery of Lactose Tolerance
- Interdependent Relationships in Ecosystems: For the Birds – Designing Solutions
NYSED's Investigation availability memo uses "Lactose Tolerance" for the released second Investigation and notes that the earlier planning memo called it "Lactose Intolerance." The availability memo and current educator guide establish four points:
- Successful completion of the three Investigations is required for admission, with "successful completion" defined locally.
- Investigation scores are not reported to NYSED and are not included in the final written-test score.
- The Investigations may count toward the 1,200 laboratory minutes.
- Approximately 15% of written-test questions measure content related to the Performance Expectations addressed by the Investigations, not recall of the specific task steps.
That last distinction matters. Current students should practice using models, identifying patterns, analyzing data, evaluating evidence, and explaining biology in unfamiliar contexts. Memorizing the order of the four old Part D procedures is not a current-exam strategy.
A Two-Path Action Plan
If you are auditing a legacy Living Environment record
- Confirm that the exam was taken no later than June 18, 2026.
- Use the conversion chart for the exact administration, not a generic raw-score calculator.
- Check the school's laboratory record if eligibility or documentation is disputed.
- Use the four lab summaries above to interpret archived Part D questions and rating guides.
If you are preparing for the current Life Science: Biology exam
- Confirm 1,200 documented laboratory minutes and satisfactory reports.
- Confirm successful completion of all three required Investigations under your school's standard.
- Practice cluster-based data and model questions instead of relying only on old five-part exams.
- Use current biology practice and the Life Science: Biology study guide for the exam now administered.

Bottom Line
The four required Living Environment labs and 13-credit Part D belong to a legacy exam that ended June 18, 2026. Their science remains useful, but current candidates must satisfy the 1,200-minute laboratory rule and complete the three Life Science: Biology Investigations. Confirm your recorded eligibility with your school, then study for the exam title you will actually take.
