Exam Facts, Format & Scoring

Quick Answer: The current Regents Examination in Earth and Space Sciences (ESS) has 45-55 questions arranged in 9-11 phenomenon-based clusters, about 60% multiple-choice and 40% constructed-response, with a 3-hour time limit. You pass with a scale score of 65 (a converted score, not 65% correct). New-standards students must complete required Investigations first; legacy Physical Setting/Earth Science students complete a Laboratory Performance Test. Its final administration is June 2026.

Two Exams During the Transition

The New York State Education Department (NYSED) is moving Earth science assessment to the New York State P-12 Science Learning Standards (NYSP12SLS). That creates two exams you might encounter in 2026:

• Regents Examination in Earth and Space Sciences (ESS) — the new, three-dimensional, standards-aligned exam. First administered June 2025.
• Regents Examination in Physical Setting/Earth Science — the outgoing legacy exam, whose final administration is June 2026.

The single most important first step is to confirm which exam your course prepared you for. Your classroom instruction, not your preference, determines which test you take. The two exams use different reference tables and a different question style, so studying the wrong format wastes effort.

How the ESS Exam Is Built

The ESS exam is phenomenon-based. Instead of isolated facts, questions are grouped into clusters built around a real-world storyline: a passage, a diagram, a data table, a map, or a photograph. You read the stimulus, then answer several linked questions about it. Expect 9-11 clusters and 45-55 total questions.

Questions come in two forms:

• Multiple-choice (MC) — four options, one best answer; roughly 60% of the test.
• Constructed-response (CR) — you write, calculate, label, plot, or explain; roughly 40% of the test. CR items reward showing work, using correct units, and citing evidence from the stimulus.

Because clusters bundle questions, a misread stimulus can cost you several points at once. Slow down on the storyline before answering.

The Lab / Investigations Requirement

New York ties Earth science assessment to hands-on work. For the ESS exam, students must successfully complete the required science Investigations during the course before they are eligible to sit the written test. Importantly, Investigation scores are not reported to the State and are not part of the final written-test score — they are an eligibility gate, not points on your transcript exam grade.

For the legacy Physical Setting/Earth Science exam, the parallel requirement is the Earth Science Laboratory Performance Test, a separate hands-on practical that students take in addition to the written exam.

Missing the lab/Investigation requirement can bar you from the written test, so treat it as a real deadline, not optional homework.

Scoring: Why 65 Is Not 65 Percent

NYSED reports Regents results on a 0-100 scale score, and 65 is the passing standard. This is a scale score, not a raw percentage. NYSED converts your raw score (points earned) into a scale score using a conversion chart published for each administration. Because of how the standards-referenced scale is set, the number of raw points needed for a 65 changes slightly from exam to exam and is usually well below 65% of the points.

Key scoring facts:

• A scale score of 65 meets the diploma assessment requirement.
• Scoring uses rubrics for constructed-response items, awarding partial credit for partially correct work.
• There is no penalty for guessing on multiple-choice, so never leave an MC blank.
• NYSED does not publish one fixed statewide pass-rate benchmark; outcomes are reported by administration, school, district, and subgroup.

What Content Is Tested

The ESS exam draws from six official content areas defined by the NYSP12SLS, with weights that overlap because the exam emphasizes connections across systems. Plan your study time roughly in these proportions:

• Space Systems (20-31%) - Earth-Sun-Moon geometry, seasons, tides, eclipses, the solar system, stars, and evidence for the universe.
• History of Earth (11-20%) - relative and absolute dating, fossils, unconformities, geologic time, and glaciation.
• Earth's Systems (20-31%) - plate tectonics, the interior, minerals, rocks, weathering, erosion, deposition, streams, and groundwater.
• Weather and Climate (11-20%) - atmospheric variables, fronts, pressure systems, moisture, energy transfer, and climate controls.
• Human Sustainability (20-31%) - resources, energy choices, water quality, hazards, climate impacts, and risk reduction.
• Engineering and Applications (3-9%) - criteria and constraints, design tradeoffs, model limits, and evidence-based solutions.

Notice that Earth's Systems, Space Systems, and Human Sustainability can each be nearly a third of the test, so they deserve the most review time. Because clusters mix content areas, a single storyline about a coastline might pull from weather, Earth's systems, and sustainability at once - so study the connections, not just isolated chapters.
