FCAT Science 8th Grade Practice Test

Fifty-two questions on the benchmarks Florida tests in grade 8 science, weighted by category the way its blueprint is.

A student tests whether the amount of fertilizer changes how tall bean plants grow. Four groups of plants get 0, 5, 10 or 15 grams, and she measures their height after three weeks. What is the test variable (independent variable)?

Time limit
160 minutes
Session
One session; a short break follows the first 80 minutes. A student still working may continue as long as a typical school day lasts.
Items
48 to 54, all multiple choice. In spring about 8 to 10 of them are field test items that do not count toward the score.

Facts: where a question's fact is stated in the benchmark or in the glossary of the specifications (Appendix C), that is the source named; every other fact rests on the federal page named on the question (NASA, NOAA, the U.S. Geological Survey, the National Park Service, the U.S. Energy Information Administration, the National Human Genome Research Institute, the National Cancer Institute), each read 2026-10-07. Licence: Own work. Questions, answer choices and explanations were written for this site from the state's public benchmarks and the public pages named on each question. Nothing is copied or reworded from a Statewide Science Assessment, an FCAT test, a released test, a sample item of the state or another practice test.

How it works

Unofficial practice for Florida's 8th grade science test, still called FCAT science; its name today is the Statewide Science Assessment. Every question is our own, written from the state's benchmarks. Not affiliated with the Florida Department of Education.

What the grade 8 science test covers

Four reporting categories: Earth and space science, physical science and life science at 27 percent each, and the nature of science at 19 percent. The blueprint draws on grades 6 and 7 too, so cells, body systems, forces, weather and the rock cycle sit beside the grade 8 benchmarks on stars, atoms, chemical change and photosynthesis.

Where each answer comes from

Every question is tied to one Florida benchmark. Where the benchmark or the glossary of the state's test specifications states the fact, that is the source. Every other fact rests on a federal page named under the answer, such as NASA for space, the U.S. Geological Survey and NOAA for Earth, water and weather, the National Human Genome Research Institute for cells and heredity.

  • Florida writes "test variable (independent variable)" and "outcome variable (dependent variable)". Learn both names for each.

Questions and answers

Is FCAT science still given in 8th grade?

Not under that name. The grade 8 test is now the Statewide Science Assessment. FCAT Science was first given in 2003, and Florida moved to FCAT 2.0 in 2011.

How many questions are on the 8th grade science test in Florida?

The state's 2026-27 fact sheet gives 48 to 54 items, all multiple choice.

How long is the Florida 8th grade science test?

It is a single 160-minute session with a short break at the halfway point, after 80 minutes. Students who need more time may keep working for up to a typical school day.

What is a passing score on the 8th grade science test?

Grade 8 scores run from 140 to 260 in five achievement levels. Level 3 starts at 203, and the state's fact sheet calls that lowest Level 3 score the passing score. A percent right here cannot be turned into a scale score.

Do 8th graders in Biology 1 take the science test?

No. A middle grades student enrolled in Biology 1 takes the Biology 1 end-of-course assessment and not the grade 8 Statewide Science Assessment. Florida law does not allow a student to be tested on both.
