The HiSET (High School Equivalency Test) exam assesses knowledge equivalent to a U.S. high school diploma. It consists of five core subjects, each delivered as a separate subtest. Test-takers must pass all five to earn a HiSET credential, which is recognized in over 20 states and valid for college admissions, employment, and military enlistment.

1. Language Arts – Reading (65 minutes, 40 multiple-choice questions + 1 essay prompt in some formats): Evaluates comprehension of literary and informational texts, including fiction, poetry, drama, workplace documents, and nonfiction. Skills include identifying main ideas, themes, author’s purpose, inferences, and vocabulary in context.
2. Language Arts – Writing (120 minutes, Part I: 60 multiple-choice; Part II: 1 essay): Tests grammar, sentence structure, organization, and writing strategies (multiple-choice), plus the ability to compose a clear, persuasive essay supported by evidence.
3. Mathematics (90 minutes, 55 multiple-choice + grid-in questions; calculator allowed for most): Covers number operations, measurement, geometry, data analysis, statistics, probability, and introductory algebra. Real-world problem-solving is emphasized.
4. Science (80 minutes, 60 multiple-choice): Spans life science, physical science, and earth/space science. Questions focus on scientific method, data interpretation (graphs, tables), experimental design, and concepts like ecosystems, energy, weather, and chemical reactions.
5. Social Studies (70 minutes, 60 multiple-choice): Integrates history, civics/government, economics, and geography. Includes analyzing primary/secondary sources, maps, charts, and timelines; key topics range from U.S. history and world events to constitutional principles and economic systems.

Each subtest is scored 1–20 (8+ passing); the essay adds 1–6 points. Accommodations (extra time, separate room) are available for documented disabilities. HiSET aligns with College and Career Readiness Standards, preparing adults 16+ (state rules vary) for postsecondary success. Total testing time: ~7 hours, often split over multiple days.
