2021 AP Test Changes Due to COVID-19

Due to the ongoing COVID-19 coronavirus pandemic, AP tests will now be held over three different sessions between May and June.

Your test dates, and whether or not your tests will be online or on paper, will depend on your school. To learn more about how all of this is going to work and get the latest information on test dates, AP online review, and what these changes means for you, be sure to check out

What Are the New AP US History Guidelines?

The AP US History course has undergone a few revisions in recent years.

First, in 2015, APUSH was revised to focus more on developing students’ skills for understanding history rather than just memorizing concepts and dates. (That update was controversial; you can read

a summary of the controversy here

if you’re interested.)

The US History guidelines were

revised again in 2019

to refine the skills-based requirements that the College Board put in place a few years ago.

We will briefly break down these new 2019-20 guidelines before getting into the chronology of US History and notes.

AP US History has three broad learning objectives:

  • Historical thinking skills (basically how you analyze what you learn)
  • Reasoning processes (historical thinking skills)
  • Thematic learning objectives (themes to look for in each period covered in AP US History)

APUSH is now also

divided up into nine units

, which each correspond to a specific time period.

We’ll quickly go over the three learning objectives below so you know what to look for as you dig into the AP US History notes, which are arranged chronologically by unit/time period.

The 6 Historical Thinking Skills for AP US History

The AP program wants to help US History students develop historical thinking skills, rather than just having them memorize a string of facts about a certain place or time period.

Especially since AP US History is notorious for requiring students to memorize tons of dates, facts, and names, the current curriculum aims to develop history skills so that the course isn’t mostly memorization-based.

Each APUSH exam question will test one or more of these skill-based objectives as well as one or more of the thematic objectives.

So keep these skills in mind as you go through the chronological notes.

Your AP US History teacher should be working on these skills with your class. If they’re not,

we recommend getting a prep book

, which will review the skills in detail and show you how to demonstrate them in the essays.

Now then, let’s look at each of these skills in detail.

Skill 1: Developments and Processes

Students should be able to identify important historical concepts, developments with significant historical impacts, and historical processes.

Skill 2: Sourcing and Situation

This skill is

all about understanding historical sources

. Students should be able to distinguish between primary and secondary sources and also be able to identify where a source came from, the source’s perspective, its intended audience, and its purpose.

Additionally, students should learn how to vet the reliability of a source and understand how the source’s perspective affects how it can be used in historical interpretation.

Skill 3: Claims and Evidence in Sources

Students should learn how to analyze arguments in primary and secondary sources. This includes identifying a source’s claim, picking out its substantiating evidence, and evaluating the quality and persuasiveness of the argument.

Students should also be able to explain this process

, especially when comparing two different sources.

Skill 4: Contextualization

With this skill, students learn to describe and analyze the context of various historical events, developments, and processes. More importantly, students should understand how to situate a particular historical event within its broader historical context.

Skill 5: Making Connections

Using historical reasoning processes (which we’ll get to in a moment), students should know how to analyze patterns and create connections between historical developments and processes. Students should also be able to explain these connections and their implications.

Skill 6: Argumentation

This skill is all about developing and defending an argument. Students should know how to make a historically defensible claim, use historical reasoning to make a point, and back up that point with evidence. Students will also learn how to corroborate, qualify, or modify an existing argument.


The 3 Reasoning Processes for AP US History

These reasoning processes are new to the 2019-20 APUSH update, and they help reinforce the new skills-based approach to US History.

These three reasoning processes are tools students will learn to use in order to develop a historical thinking mindset

that allows them to intellectually engage with historical subject matter.

Reasoning Process 1: Comparison

Students should develop the ability to make logical and accurate comparisons between different historical developments, periods, and processes. This involves picking out similarities and differences, explaining them, and connecting them to greater historical significance.

Reasoning Process 2: Causation

With this reasoning process, students should learn how to discern, describe, and explain the causes and/or effects of different historical developments and processes. This includes explaining the relationship between events, understanding the differences between primary and secondary causes, and describing the short- and long-term effects of events.


students should be able to explain how relevant context influenced a historical development or process

and discuss its significance.

Reasoning Process 3: Continuity and Change

Students should learn how to identify, describe, and explain patterns of continuity and change over time. Also, students should be able to explain the relative historical significance of specific historical developments in relation to larger historical patterns, developments, and/or events.

Have you ever heard the phrase “missing the forest for the trees”? The same goes here—the AP program doesn’t want you to memorize a bunch of years and names without understanding the larger relevance of them.

The 8 Thematic Learning Objectives for AP US History

Beyond just the basic facts of US history and broad historical thinking skills, the AP program wants you to get a bigger-picture understanding of major themes and developments across America’s history, just as you would in a college course.

The goal is to be able to connect these themes between different periods in US history and be able to discuss them in an essay.

As we get into the concept outline, which breaks down APUSH by time periods/units and where we are linking to notes,

think about these themes and see whether you can connect them to the outline notes

. These are important themes to trace throughout all of your AP US History studying!

  • Theme 1: American and National Identity (NAT):

    How and why definitions of American and national identity and values have developed, including citizenship, constitutionalism, foreign policy, assimilation, and American exceptionalism

  • Theme 2: Work, Exchange, and Technology (WXT):

    The factors behind the development of systems of economic exchange, particularly the role of technology, economic markets, and government

  • Theme 3: Geography and the Environment (GEO):

    The role of geography and both the natural and human-made environments on social and political developments in what would become the United States

  • Theme 4: Migration and Settlement (MIG):

    Why and how the various people who moved to and within the United States both adapted to and transformed their new social and physical environments

  • Theme 5: Politics and Power (PCE):

    How different social and political groups have influenced society and government in the United States, as well as how political beliefs and institutions have changed over time

  • Theme 6: America in the World (WOR):

    The interactions between nations that affected North American history in the colonial period, and on the influence of the United States on world affairs

  • Theme 7: American and Regional Culture (ARC):

    How and why national, regional, and group cultures developed and changed as well as how culture has shaped government policy and the economy

  • Theme 8: Social Structures (SOC):

    How and why systems of social organization develop and change as well as the impact these systems have on the broader society

AP US History Notes by Unit and Time Period

The AP US History course is

organized by units, or chronological periods

, as well as the historical skills and themes discussed above. In other words, this is your basic “first A happened, then B, then C” structure that you’re probably used to from past history classes, as well as the specific dates, names, and events of history.

After all, a great essay about the development of democracy in America would be weakened if you didn’t know the year the Constitution was ratified!

That was in 1788, by the way.

So yes, chronology is the easiest way to think about history.

But remember to think about the eight themes and try to connect them to the basic facts you’re learning.

For example, when thinking about secession, you should know when the Southern states seceded (in 1860 and 1861),

but you could also connect the “American and Regional Culture” theme to explain why

: “The belief in a distinctly Southern way of life and a refusal to abandon it drove the Southern states to secede.”

In short, understanding the overarching themes will help you gain a broader understanding of the names and dates you’re learning. Plus, being able to write about them will take your essays from good to great.

The following chapter outlines come from

AP Study Notes

. The source is

The American Pageant


one of the

best AP US History textbooks


The time periods don’t always exactly match up with AP’s guidelines, which is going to be true for most textbooks (there are only a few out there written exclusively for APUSH).

But we have organized the outlines so they mostly match up with the AP US History’s units and division of the timeline.

Whether you’re using

The American Pageant

or not, these outlines should provide you with useful overviews, which can help you study over the course of the year or in the run-up to the AP exam in May.

Unit 1: 1491-1607 (4-6% of Exam)

Unit 2: 1607-1754 (6-8% of Exam)

Unit 3: 1754-1800 (10-17% of Exam)

Unit 4: 1800-1848 (10-17% of Exam)

Unit 5: 1844-1877 (10-17% of Exam)

Unit 6: 1865-1898 (10-17% of Exam)

Unit 7: 1890-1945 (10-17% of Exam)

Unit 8: 1945-1980 (10-17% of Exam)

Unit 9: 1980-Present (4-6% of Exam)

Notice that the textbook’s chapters

fall roughly within the APUSH guidelines for chronology

in terms of the amount of time spent on each period.

All US history textbooks approved by the College Board will have good coverage of all chronological topics, so if you have chapter guides or notes from your own APUSH class’s textbook, you can (and should!) use those as well.
