What is on the HiSET

The HiSET is five subtests: Language Arts Reading, Language Arts Writing, Mathematics, Science and Social Studies. Almost every question is multiple choice, and Writing adds one essay.

What each subtest covers

  • Reading: literary texts (40%) and informational texts (60%), usually 400 to 600 words each, including poems, memoirs, essays and editorials.
  • Writing: organization of ideas (22%), language facility (43%) and writing conventions (35%) in drafts you revise, plus an essay arguing your own position on two texts.
  • Mathematics: numbers and operations (19%), measurement and geometry (18%), data, probability and statistics (18%) and algebraic concepts (45%).
  • Science: life science (49%), physical science (28%) and earth science (23%), mostly read through experiments, tables and graphs.
  • Social Studies: history (35%), civics and government (35%), economics (20%) and geography (10%), read through documents, maps and graphs.

What that means for your study

Algebra is almost half of the Math subtest, and life science is about half of Science, so those deserve the most time. Each subtest can be booked on its own day, so many people take their strongest one first.
