CLEP History of the United States I Study Guide

About 70 percent of the questions on CLEP History of the United States I cover 1790 to 1877, not the colonial period most readers spend the most time studying. Plan 30 to 60 hours, front-load the antebellum decade and Reconstruction, and you skip 30 hours of textbook time on material that won't be tested.

The exam is 120 multiple-choice questions in 90 minutes, worth 3 ACE-recommended semester hours, $97 to register as of May 2026. If you have AP US History within the last two years, you can probably get there in 10 to 20 hours of focused review.

I took this exam for my degree at Thomas Edison State University, where it filled the HIS 113 slot. It's one of the more readable CLEPs if you are comfortable with a Brinkley-style survey textbook. It's also one of the first exams I'd recommend to anyone testing into a humanities or general-education requirement, because the question style is straightforward and the source material is everywhere.

Quick facts

How hard is it?

Honest answer: medium. It is harder than CLEP American Government (which is narrower) and easier than CLEP Western Civilization I (which spans more centuries and more geographies). What makes it easier than people fear: there is no essay, no short answer, no document-based question. It's all multiple choice, and partial knowledge often gets you to the right answer through process of elimination.

Common mistakes on this exam

Four patterns I see again and again, most of which would be obvious if you saw the score breakdown.

1. 01

   Studying like a high-school US History survey.

   Most readers spend the most hours on the colonies (Pilgrims, Jamestown, the French and Indian War). About 70 percent of the actual exam covers 1790 through 1877, where high-school surveys spend the least time.

2. 02

   Memorizing dates instead of cause and effect.

   Question stems on this exam read "Which of the following best explains..." far more often than "In what year did..." If you can recite the date of the Missouri Compromise but cannot say why it mattered, you will lose those points.

3. 03

   Skimming Reconstruction.

   The cutoff is 1877 for a reason. The 13th, 14th, and 15th Amendments, the Freedmen’s Bureau, sharecropping, the rise and collapse of Radical Reconstruction, and the Compromise of 1877 are all on the table. Most study guides spend 20 minutes here. Plan a real evening.

4. 04

   Ignoring the Cultural and Intellectual bucket.

   Twenty percent of the exam is transcendentalism, the Great Awakenings, antebellum reform writers, and the American Renaissance. Most free study guides skim it. Spend at least 4 to 6 hours here even if it feels off-topic; it isn’t.

Who should take it

Take this exam first if you have a recent US history course on your transcript (high school AP US History, a community-college survey, or strong homeschool coverage). The exam mirrors a standard first-semester US history survey, so recent coursework is a real edge.

Take it second or third if you are a working adult coming back to school after a long gap. Pair it with CLEP US History II (the second-semester counterpart) for a clean 6 credits in one general-education area.

Skip it (for now) if you are testing for a STEM-heavy degree and your school accepts CLEP US History as elective rather than gen-ed credit. In that case, knock out a math or natural-science CLEP first, where the credit lands inside your major's gen-ed requirement.

Strong fit:

• TESU, Excelsior, and Charter Oak students using CLEP for the lower-division humanities requirement
• Military service members using DANTES funding (CLEP is free for eligible service members and many veterans)
• Homeschoolers building a transcript that mixes dual enrollment and credit-by-exam

How to study

Plan for 30 to 60 hours of study time if you have not taken a US history course in the last five years. If you took AP US History within the last two years and scored a 4 or 5, plan for 10 to 20 hours of review.

1

Week 1

8 to 12 hours

Read or skim a survey textbook (Brinkley, Foner, or Tindall and Shi). One book, all the way through.

2

Week 2

8 to 12 hours

Watch a video survey to fill gaps. Khan Academy is the strongest free option.

3

Week 3

6 to 10 hours

Drill the post-1790 material. Eighty-four of the 120 questions live there.

4

Week 4

8 to 12 hours

Two full-length timed practice exams. Flying Prep's are scored on the 20 to 80 ACE scale.

5

Final 2 to 3 days

3 to 6 hours

Review your weakest content area only. Don't re-read the textbook.

Materials I'd actually pay for:

• Flying Prep CLEP US History I. This is the prep tool I built after I finished my degree, because nothing on the market handled CLEP the way it should be handled. You get spaced-repetition flashcards on every concept the exam tests, full-length practice exams scored on the 20 to 80 ACE scale, and a confidence score per content area that tells you when you're actually ready to sit. If you only buy one prep tool, this is the one I'd buy.
• The official CLEP Examination Guide for US History I ($10 PDF). Sample questions written by the same people who write the actual exam. Worth the $10 for the question-style calibration alone.

Materials I'd skip:

• Princeton Review and REA prep books. They treat the exam as something to memorize, when it is actually structured around thematic understanding. You will over-prepare on dates and under-prepare on cause-and-effect.
• Modern States as a study tool. The course content is shallow and the videos are slow. Take their free course only for the exam voucher: completing it earns a $97 CLEP fee waiver, which is real money. Then ignore the course content and study with a tool that takes the exam seriously.
• Quizlet decks scraped from random users. Half have factual errors that will train wrong answers into your head.

What this exam covers

College Board publishes the breakdown by theme; the chronological emphasis is documented separately and is the more important framing for study planning.

• Political institutions, political developments, and public policy25%
• Social developments25%
• Cultural and intellectual developments20%
• Economic developments15%
• Diplomacy and transnational interactions15%

Chronological emphasis

1500-1789 (30%)

1790-1877 (70%)

Political institutions, political developments, and public policy (25 percent)

The biggest single bucket and the one where College Board most rewards readers who understand the documents, not just memorize their dates. Expect questions on:

• Colonial governance structures (royal, proprietary, charter), colonial assemblies, and Salutary Neglect
• The road to independence: the Stamp Act, the Townshend Acts, the Declaration, the Articles of Confederation
• The Constitution and the Bill of Rights, ratification debates (Federalists vs. Anti-Federalists), and the rise of the first party system
• Jacksonian democracy, the spoils system, the Bank War, and the Indian Removal Act
• Antebellum political crises: the Missouri Compromise, the Compromise of 1850, Kansas-Nebraska, Dred Scott
• The Civil War as a constitutional crisis and the Reconstruction-era amendments (13th, 14th, 15th)

Social developments (25 percent)

Tied for the largest bucket. The exam puts heavy weight on the lived experience of different American populations, not just political leaders. Topics include:

• Indigenous societies before contact and the demographic collapse from disease and displacement
• The development of slavery in the Chesapeake versus the Lowcountry versus the North, and how slave codes evolved
• Immigration waves: Scots-Irish, German, and the mid-19th-century Irish and German waves
• Women's roles, the cult of domesticity, and the Seneca Falls Convention (1848)
• Reform movements: temperance, abolition, prison and asylum reform, public schools (Horace Mann)
• Religious revivals: the First and Second Great Awakenings

Cultural and intellectual developments (20 percent)

The bucket students prepare for least and lose the most points on. Plan to know:

• Puritan thought, the Half-Way Covenant, and Jonathan Edwards
• The Enlightenment in colonial America (Franklin, Jefferson)
• Transcendentalism (Emerson, Thoreau) and the American Renaissance (Hawthorne, Melville, Whitman)
• Education reform and the rise of the public school
• Antebellum reform literature, including Uncle Tom's Cabin

Economic developments (15 percent)

More concept than memorization. Focus on:

• The mercantile system and the Navigation Acts
• Tobacco, rice, and indigo as colonial cash crops, and the shift to cotton after 1793
• The Market Revolution: canals, the Erie Canal, early railroads, the factory system
• Hamiltonian finance: the national bank, assumption of state debts, the tariff
• Sectional economies leading into the Civil War

Diplomacy and transnational interactions (15 percent)

The smallest bucket but a high-yield study target because the topics are finite:

• Anglo-French rivalry and the French and Indian War
• The XYZ Affair, the Quasi-War, the Louisiana Purchase
• The War of 1812 and the Treaty of Ghent
• The Monroe Doctrine
• Manifest Destiny, the Mexican-American War, and the Treaty of Guadalupe Hidalgo

Test day

The exam runs for 90 minutes and contains approximately 120 questions. You get a built-in clock, an erasable note board (at test centers), and the option to flag questions for review. Some questions are unscored pretest items, so don't panic if a question looks unfamiliar; College Board uses live exams to test new questions.

The exam is computer-based and delivered at one of the roughly 2,000 CLEP test centers nationwide, or remotely via College Board's remote-proctoring partner. Remote proctoring requires a webcam, a quiet room, a clear desk, and a government-issued ID. The remote test costs the same $97 plus a remote-proctoring fee.

Score is reported as a scaled score from 20 to 80. The ACE-recommended passing score is 50. Most institutions follow ACE's recommendation, but each school sets its own credit-granting policy, so confirm with your registrar before you sit.

You'll see your score on screen at the end of the exam. There is no essay component for this CLEP, so the score is final at submission.

A few practical test-day notes that will save you points:

• Pace yourself at 45 seconds per question. Ninety minutes for 120 questions averages 45 seconds each. If you're spending 90 seconds on a single question, flag it and move on. You can always come back.
• Read every answer choice before selecting. CLEP often includes one answer that is partly true and one that is fully true. The first plausible option isn't always the best.
• Don't leave anything blank. There is no guessing penalty on CLEP exams. An educated guess is always better than a blank.
• Use process of elimination on the cultural questions. If you don't recognize a name, you can usually rule out the wrong era or wrong region from the answer choices alone.
• Don't change answers without a reason. Your first instinct is usually correct on a thematic survey exam. Change an answer only if you spot a specific reason your first choice was wrong.

After passing

A passing score is worth 3 semester hours under ACE's recommendation, typically applied to a first-semester US history survey course (HIS 113, HIST 1301, or your school's equivalent). At the Big Three (TESU, Excelsior, Charter Oak), this maps cleanly to a lower-division humanities or social-sciences general-education slot.

Natural next exams:

• CLEP History of the United States II: 1865 to the Present, the second-semester counterpart, also worth 3 credits at the ACE recommendation
• CLEP American Government if you found the politics-and-policy bucket easy
• CLEP Western Civilization I or II if you liked the survey format and want to fill another humanities slot

Send your official score report to one school for free at registration. After that, additional reports cost $20 each. Most students should send the report directly to their degree-granting institution, not to multiple schools, unless they're transferring.

FAQ

How many questions are on the CLEP History of the United States I exam? Approximately 120 multiple-choice questions, with 90 minutes to finish. Some questions are unscored pretest items.

What's a passing score on CLEP US History I? The ACE-recommended passing score is 50 on a 20 to 80 scale. Most schools follow ACE's recommendation, but each institution sets its own credit policy, so verify with your school's registrar.

How many credits is CLEP US History I worth? ACE recommends 3 semester hours of lower-division credit, typically applied to a first-semester US history survey course.

How long should I study for CLEP US History I? Most adult learners need 30 to 60 hours. If you took AP US History within the last two years and scored a 4 or 5, you can probably get there in 10 to 20 hours of focused review.

Is CLEP US History I harder than CLEP US History II? About the same difficulty for most students. US History I has more content per year (you cover roughly 380 years), while US History II compresses 160 years into the same 120 questions, which means more density per decade. Pick the one whose era you find more interesting and start there.

What time period does the exam emphasize most? About 70 percent of the questions cover 1790 to 1877. The colonial era (1500 to 1789) is roughly 30 percent. Plan your study weight accordingly.

Can I take CLEP US History I online? Yes. College Board offers remote proctoring for most CLEP exams, including this one. You'll need a webcam, a quiet room, a clear desk, and a government-issued ID, and the proctoring fee is added to the $97 exam fee.

What's the best free study material for CLEP US History I? Khan Academy's US History course is the best free option for actually learning the material: well-paced, accurate, and stronger on the post-1790 era than most free alternatives. Modern States offers a free course but the content is shallow; take their course only for the $97 exam voucher it awards on completion, and study elsewhere.

Does CLEP US History I count toward a history major? Usually no. Most colleges accept it as general-education credit or as elective credit, not as a substitute for an upper-division history course in a history major. Check with your specific program.

How quickly can I get my score? You see your unofficial score on screen immediately after the exam. Official score reports are available to your designated school within a few business days.
