NYS 8th grade science is the Intermediate-Level Science Test (ILS) — a cumulative test covering Grades 6-8 NYSSLS standards, 53 interactive CBT items across 10 phenomenon-based clusters, and the direct bridge to Regents Living Environment / Earth Science / Chemistry.
Grade 8 NYS Science is the Intermediate-Level Science Test (ILS) — a cumulative assessment covering Disciplinary Core Ideas from Grades 6, 7, AND 8 under the New York State Science Learning Standards (NYSSLS). Spring 2024 was the first operational administration under NYSSLS at Grade 8; pre-2024 tests aligned to 1996 standards are retired and not comparable.
The 2024 administration had 25 multiple-choice items + 28 constructed-response items = 53 items, organized into 10 question clusters built around real-world phenomena — significantly more items than the Grade 5 Elementary-Level Science Test (34 items in 7 clusters). Sample clusters span energy transfer (skateboarding mechanics, kinetic and potential energy), genetics and evolution (heredity, natural selection), physics (Newton's laws, waves), Earth systems (plate tectonics, climate change), and life sciences (cells, ecosystems, food webs). Each cluster presents a phenomenon and asks 4-7 linked items demonstrating 3D learning across DCI (content) + SEP (practice) + CCC (crosscutting concept).
NYSSLS at Grade 8 covers NGSS MS-PS (matter, motion, energy, waves), MS-LS (cells, ecosystems, heredity, evolution), MS-ESS (Earth's history, weather, climate change, human impacts), and MS-ETS (engineering design). Roughly two-thirds of test points come from Science and Engineering Practices + Crosscutting Concepts; only one-third is pure content recall — the same radical shift as Grade 5.
44% of New York eighth-graders scored Level 3 or higher on the 2024-25 NYSSLS Intermediate-Level Science Test — up from 34% in 2024 (+10 ppt). More than half of NY eighth-graders still aren't proficient, but the 10-point jump reflects classrooms adjusting to the new format. The Grade 8 NYSSLS test is the direct bridge to the Regents Living Environment (most common Grade 9-10 Regents science), Regents Earth Science, and Regents Chemistry — Regents Living Environment in particular shares the 3D-learning structure and phenomenon-based items.
NYS uses 4 performance levels: Level 1 (below standard), Level 2 (partially proficient), Level 3 (proficient), Level 4 (excels). Level 3 or higher is the federal 'on grade level' target.
Spring 2026 is the first year of universal computer-based testing across every NYS Grades 3-8 test. NWEA is the statewide CBT vendor. New digital item types include drag-and-drop, hot text, multi-select, inline choice, dynamic graphing, and (for Math) the equation editor. Paper administration is available only as an IEP/504 accommodation. Free practice on the NYSED Question Sampler (nysed.gov/state-assessment/question-sampler) and CBTSupport.nysed.gov.
Up from 34% in 2023-24 (+10 ppt). 2024 was first operational year under NYSSLS — not comparable to pre-2024 tests aligned to 1996 standards. More than half of NY eighth-graders still aren't proficient.

Grade 8 NYSSLS Intermediate-Level Science covers Disciplinary Core Ideas cumulatively across Grades 6, 7, and 8 — significantly broader than the Grade 5 elementary test. Three disciplines: Physical Sciences (MS-PS — matter, motion, energy, waves), Life Sciences (MS-LS — cells, ecosystems, heredity, evolution), and Earth & Space Sciences (MS-ESS — Earth's history, weather, climate change). Engineering, Technology and Applications of Science (MS-ETS) threads across all three. Two-thirds of test points come from Science and Engineering Practices + Crosscutting Concepts, not pure content.
| Reporting Category | % of Test | What's Tested |
|---|---|---|
| Physical Sciences (MS-PS) — DCIs across Grades 6-8 | ~25-35% | MS-PS1 (matter — atoms, molecules, chemical reactions, conservation of mass), MS-PS2 (motion and forces — Newton's laws, force and motion), MS-PS3 (energy — kinetic, potential, energy transfer, thermal energy), MS-PS4 (waves — sound, light, electromagnetic spectrum, digital signal transmission). Phenomena include skateboarding mechanics, sound waves, chemical reactions. |
| Life Sciences (MS-LS) — DCIs across Grades 6-8 | ~25-35% | MS-LS1 (cells — structure, function, photosynthesis, cellular respiration), MS-LS2 (ecosystems — energy flow, biodiversity, ecosystem dynamics), MS-LS3 (heredity — DNA, inheritance, genetic variation), MS-LS4 (evolution — natural selection, fossil evidence, common ancestry). Phenomena include genetic traits across generations, ecosystem disruption, fossil records. |
| Earth & Space Sciences (MS-ESS) — DCIs across Grades 6-8 | ~20-30% | MS-ESS1 (Earth's place in the universe — sun, moon, planets, gravity), MS-ESS2 (Earth's systems — plate tectonics, rock cycle, water cycle, weather and climate), MS-ESS3 (Earth and human activity — natural resources, natural hazards, human impact, climate change). Phenomena include earthquakes and tectonic motion, climate change indicators, weather systems. |
| Engineering, Technology, Applications of Science (MS-ETS) | (threaded across all clusters) | MS-ETS1 (engineering design — define problems, design solutions, optimize, evaluate trade-offs). Not a separate reporting category by itself; engineering practices appear inside clusters across MS-PS, MS-LS, and MS-ESS, asking students to design or evaluate solutions to real-world phenomena (water treatment, renewable energy, ecosystem conservation). |
| Science & Engineering Practices + Crosscutting Concepts | ~67% of test points (threaded across all clusters) | The 8 SEPs (asking questions, modeling, planning investigations, analyzing data, mathematical reasoning, constructing explanations, arguing from evidence, communicating information) and 7 CCCs (patterns, cause-effect, scale, systems, energy-matter, structure-function, stability-change) are integrated into every item. Two-thirds of test points come from these — the radical shift from old NY science tests. |
Grade 8 NYSSLS Intermediate-Level Science is the direct bridge to Regents science exams — Living Environment (most common Grade 9-10 Regents science), Earth Science, and Chemistry. Spring 2024 was the first operational year under NYSSLS at Grade 8, a radical departure from the 1996-standards test that came before. The shift to 3D learning means every item integrates content (DCI) + practice (SEP) + crosscutting concept (CCC), with roughly two-thirds of test points coming from practice + concept, not pure content recall. The test is cumulative across Grades 6-8 — 53 items in 10 phenomenon-based clusters spanning matter and energy, cells and ecosystems, heredity and evolution, Earth's history and climate change. The CBT interface is more advanced than any other NY test: drag-and-drop sorting, dynamic graphing (students build their own graphs from data), and simulations let students manipulate variables and observe outcomes. The 44% Level 3+ rate in 2024-25 (up from 34% in 2024) reflects classrooms still adjusting to a fundamentally new test design. For families: strong Grade 8 performance — especially in MS-LS (cells, ecosystems, heredity, evolution) — directly previews Regents Living Environment, which shares the 3D-learning structure and phenomenon-based items. Investment in NYSSLS at Grade 8 pays off for the entire high-school science sequence.
Don't cram only Grade 8 content. The Intermediate-Level Science Test is CUMULATIVE across Grades 6-8 NYSSLS standards. Your child needs MS-PS content from Grade 6 (matter, atoms, forces, motion), MS-LS content from Grade 7 (cells, ecosystems, heredity), AND MS-ESS/MS-PS extensions from Grade 8 (Earth systems, climate, energy, waves). Six months of weekly review (one DCI per week) beats a March cram. Use Mystery Science middle-school content, the NYSED released items, and the Question Sampler clusters.
Practice with the NYSED Question Sampler clusters specifically. The interactive CBT — drag-and-drop sorting, dynamic graphing, simulations — is significantly more advanced than NYS Math or ELA. Fifteen to thirty minutes of practice clicking through Grade 8 clusters on nysed.gov/state-assessment/question-sampler removes the digital learning curve. Question Sampler clusters released after 2024 are the most realistic preview available.
Drill three-dimensional thinking. Every item integrates DCI (content) + SEP (practice — analyzing data, constructing explanations, modeling, arguing from evidence) + CCC (crosscutting concept — patterns, cause-effect, systems, energy-matter, structure-function, stability-change). Train your child to identify each on practice items: 'What science content is this testing? What scientific practice is the question asking? What crosscutting concept connects it?' This metacognitive habit transfers directly to NYSSLS items and to Regents Living Environment.
Treat Grade 8 as Regents Living Environment / Earth Science / Chemistry prep. The Grade 8 NYSSLS test is the direct bridge to Regents science exams (most NY students take Regents Living Environment in Grade 9 or 10). The 3D-learning structure and phenomenon-based items transfer directly to Regents Living Environment in particular. Strong Grade 8 performance in MS-LS (cells, ecosystems, heredity, evolution) directly previews Regents Living Environment content. Use the Grade 8 result to identify gaps before high-school science begins.
Build data-interpretation skills. Roughly two-thirds of NYSSLS test points come from SEPs and CCCs, not pure content — and the most-tested practice is analyzing data. Items present graphs, scatter plots, tables, and simulations, then ask students to identify patterns, draw conclusions, or evaluate claims based on the data. Weekly practice reading scientific graphs (from kids' science magazines, news articles, NYSED released clusters) compounds across the test. This is also the highest-leverage skill for high-school science and AP Biology / Chemistry.
Cumulative content across Grades 6, 7, and 8 under NYSSLS. Physical Sciences (matter — atoms, chemical reactions; motion and forces — Newton's laws; energy — kinetic, potential, thermal; waves — sound, light), Life Sciences (cells, ecosystems, heredity and DNA, evolution and natural selection), Earth & Space Sciences (Earth's place in universe, plate tectonics, rock cycle, weather and climate change, human impact), and engineering design threaded throughout. The test uses 10 question clusters built around real-world phenomena.
Yes — and the interactive CBT is more advanced than NYS Math or ELA. The NWEA platform supports drag-and-drop sorting, dynamic graphing (students build graphs from data), simulations (manipulate variables and observe outcomes), and multi-part item bundles. Phenomenon-based clusters present text, images, video, or data — students interact with the phenomenon before answering. Practice on the NYSED Question Sampler is more important here than for any other subject.
Single session, single day, untimed (since 2016). Schools plan a minimum of 120 minutes of administration time — longer than Grade 5 (90 minutes) reflecting the higher item count (53 vs. 34). Most eighth-graders finish within 120-150 minutes, with constructed-response items and interactive simulations taking the most time. As with every NYS test, no clock cuts a student off who is still working productively within the school day.
53 items total — 25 multiple-choice + 28 constructed-response — organized into 10 question clusters built around real-world phenomena. Each cluster typically has 4-7 linked items including 2-4 constructed-response items asking students to explain reasoning, propose explanations from data, model phenomena, or evaluate engineering solutions. The 28 CR items at Grade 8 (vs. 15 at Grade 5) reflect higher expectations for explanation depth at the intermediate level.
NGSS-derived Disciplinary Core Ideas across Grades 6-8: MS-PS1 through MS-PS4 (matter, motion, energy, waves), MS-LS1 through MS-LS4 (cells, ecosystems, heredity, evolution), MS-ESS1 through MS-ESS3 (universe, Earth systems, human impact), and MS-ETS1 (engineering design). Plus the 8 Science and Engineering Practices (asking questions, modeling, analyzing data, etc.) and 7 Crosscutting Concepts (patterns, cause-effect, systems, energy-matter, etc.) threaded into every item.
It is one of the hardest NYS tests by proficiency rate — 44% Level 3+ in 2024-25, well below Math (47% at Grade 8) and ELA (52% at Grade 8). The radical NYSSLS shift to 3D learning (content + practice + concept in every item) and the cumulative format (covering 3 years of standards) explain most of the difficulty. The +10 ppt jump from 34% in 2024 to 44% in 2025 reflects classrooms adjusting to the new format. More than half of NY eighth-graders still aren't proficient — read as the toughest middle-school science test in NY's history.
A real-world phenomenon — like skateboarding energy and friction, genetic inheritance across generations, gravitational forces and orbital motion, Earth processes (plate tectonics, weather systems), or climate change indicators — that anchors 4-7 linked items. Students see the phenomenon presented with text, images, video, or data, then answer items demonstrating 3-dimensional learning across DCI (content), SEP (practice — modeling, analyzing data, constructing explanations), and CCC (crosscutting concept — patterns, cause-effect, systems, energy-matter). 10 clusters at Grade 8.
No — the legacy hands-on Performance Test (a separate event scored as part of the pre-2024 assessment) has been retired with the 1996 standards. Under NYSSLS, classroom-based 'ILS Investigations' (Intermediate-Level Science Investigations) are still required throughout the school year, but they are used for instruction, not as a separately scored portion of the state test. Phenomenon-based simulations and 3D-learning clusters on the CBT now carry the assessment weight the Performance Component used to carry.
