Grade 8 is the second and last grade where Ohio tests science on the state test — physical-science-heavy, covering matter, forces, and energy — with 63% of eighth graders reaching grade level in 2025.

Grade 8 science is the second and final grade where Ohio tests science on the state test (the other is grade 5), so it carries extra weight as a measure of science learning before high school. It's a physical-science-heavy test.
The test measures Ohio's Learning Standards in Science across three reporting categories: Earth & Space Science, Life Science, and Physical Science — with physical science (matter, forces and motion, and energy, including the conservation of matter and Newton's laws) as the core. Earth and space topics include plate tectonics and the universe, and life science includes cells and heredity.
In 2025, 63% of Ohio eighth graders scored Proficient or above (scale 700+ — "on grade level") in science — close to grade-5 science (64%).
Ohio's State Tests are online, two-part tests on Cambium (paper as an accommodation). Grade-8 science is concept-based; no calculator is needed.
Proficient + Accomplished + Advanced (scale 700+ = on grade level). One of only two OST science grades. Basic and Limited are below grade level.

Grade 8 science on the OST is organized into three reporting categories from Ohio's Learning Standards in Science, with Physical Science (matter, forces, energy) as the core. Exact per-category weights are in ODEW's blueprints and not restated here.
| Reporting Category | What's Tested |
|---|---|
| Physical Science | The core of grade-8 science: structure of matter, forces and motion (Newton's laws), and energy, including the conservation of matter and energy. |
| Earth & Space Science | Plate tectonics and Earth's history, and the universe and objects in the solar system. |
| Life Science | Cells, heredity, and the diversity and interactions of living things. |
Prioritize physical science — matter, forces and motion, and energy are the core of grade-8 science. Concrete examples (conservation of mass, Newton's laws) make them stick.
Review across the two-year gap — because science isn't tested in grades 6 or 7, eighth graders can arrive rusty. Steady review beats cramming.
Practice interpreting data and diagrams — the online test uses charts, models, and experiments your child should read confidently.
Connect concepts to real experiments — grade-8 science rewards understanding cause and effect, not just memorized facts.

No. Science is tested on the OST at only grades 5 and 8. There's no science test in grades 3, 4, 6, or 7, so grade 8 is one of just two science checkpoints before high school.
In Spring 2025, 63% of Ohio eighth graders scored Proficient or above (on grade level) in science — close to grade-5 science (64%).
'On grade level' means Proficient or above (scale score 700+). Basic and Limited are below grade level.
