The HiSET^® Science Test measures your knowledge of life science, physical science, and Earth science, and space science. You will be tested with questions that are similar to the science covered in grades 9 through 12. Over half of the science questions measure your basic understanding, principles, concepts, and vocabulary associated with physical science, life science, and Earth and space science.

The science test is 80 minutes long and contains 50 multiple choice questions from the areas of Physical science, Life science, and Earth and space science.

The test features questions that are based on science-related passages, graphs, tables, charts, and diagrams. More than half of the science test may include visuals, which means you’ll spend as much time studying a chart or graph as you will reading a question.

The HiSET Science subtest measures your ability to use science content knowledge, apply principles of scientific inquiry, and interpret and evaluate scientific information. Most of the questions include descriptions of scientific investigations and their results. Scientific information is based on reports that might be found in scientific journals. Graphs, tables and charts are used to present information and results.

The HiSET science questions use material from a variety of content areas such as: physics, chemistry, botany, zoology, health and astronomy. You may be asked to identify the research question of interest, select the best design for a specific research question and recognize conclusions that can be drawn from results. You may also be asked to evaluate the adequacy of procedures and distinguish among hypotheses, assumptions and observations.
