Every August, I tell my students to download the AP History Course and Exam Description (CED). Almost every one of them does. Then, like many AP teachers, I watch it quietly disappear into the depths of their Google Drive, never to be opened again.
Ironically, that was my fault.
During the first year of the redesigned AP History course, I did not spend much time with the CED in my classroom either. Like many teachers, I viewed it primarily as a planning document—a guide for building my curriculum rather than a resource for students.
That perspective changed because of my work with the AP History program.
Whenever discussions arose about whether a particular concept, event, or example belonged on the exam, the conversation always returned to one document: the Course and Exam Description. If there was uncertainty about what students were expected to know, we opened the CED. Again and again, it became the common reference point for our conversations.
Eventually, I had one of those moments that, in hindsight, seemed obvious.
If experienced AP educators continually returned to the CED to clarify expectations, why were my students not using it?
The challenge was that the CED is not written like a textbook. It intentionally operates at a higher level of abstraction. The Historical Developments do not provide lengthy narratives or exhaustive lists of names and dates. Instead, they present broad historical claims and leave room for teachers and students to supply the specific evidence that supports them. That flexibility is one of the document's greatest strengths, but it can also make the CED feel intimidating to students encountering it for the first time.
That was when I realized that the goal should not be simply to have students read the CED. They needed to learn how to work with it.
After a little trial and error, I developed a simple annotation strategy that transformed the CED from a document students ignored into one they referenced throughout the year. Rather than memorizing isolated facts, students began connecting Historical Developments to concrete evidence from their textbook, documenting their examples, and—perhaps most importantly—thinking about history the way historians do.
One of the biggest misconceptions about the Course and Exam Description is that it is only for teachers. Certainly, it serves as the blueprint for an AP course, but it is also one of the most valuable learning resources students already have.
The key is understanding what the Historical Developments actually are.
They are not lists of facts to memorize. They are historical arguments. Each Historical Development makes a claim about the past. Students are not expected simply to recognize those claims. They are expected to explain them, support them with evidence, and apply them in new contexts throughout the AP Exam.
The CED provides the framework. Your textbook, class discussions, primary sources, and other instructional materials provide the evidence.
Once my students began looking at the CED through that lens, everything changed. Instead of asking, "What do I have to memorize?," they began asking, "What evidence supports this Historical Development?" That subtle shift moved them away from passive studying and toward genuine historical thinking.
To help students bridge the gap between the broad historical claims in the CED and the concrete evidence they encountered in their textbook, I developed four simple questions. We ask these same four questions every time we encounter a Historical Development.
When my students first begin working with the CED, I tell them that we are not going to read it the way we would read a textbook. Instead, we are going to interrogate it. Every Historical Development has something to tell us, but we have to ask the right questions.
Over the years, these four questions have become one of the most valuable instructional routines in my classroom. Individually, they are simple. Together, they transform the CED into one of the most powerful study tools students will use all year.
The first thing students do is highlight every proper noun they see.
This is usually the easiest step because students are already comfortable identifying names, places, organizations, legislation, and historical events. If a Historical Development mentions the Missouri Compromise, Andrew Jackson, the Democratic Party, or the Second Great Awakening, those proper nouns are highlighted immediately. They become visual anchors on the page.
Students quickly discover, however, that many Historical Developments contain very few proper nouns. That is intentional. The CED is designed to describe broader historical patterns, not provide every example students should know. That is where the annotation process shifts from identifying information to constructing knowledge.
For every Historical Development, I ask students to add two or three additional examples from our textbook. If the CED discusses efforts to unify the American economy, students might add Henry Clay, the American System, protective tariffs, and the Second Bank of the United States. If it discusses sectional tensions, they might include the Missouri Compromise or the Tallmadge Amendment. Those examples do not come from Google or an AI search. They come directly from the course textbook.
I also encourage students to write a brief explanation showing how each example supports the Historical Development. The goal is not simply to collect evidence. The goal is to explain why that evidence matters.
By the time students finish a unit, every Historical Development has become connected to specific historical evidence. Instead of memorizing disconnected names and dates, students are organizing evidence around larger historical ideas.
Once the proper nouns are identified, students begin underlining the words that often receive the least attention—the adjectives, qualifiers, and descriptive phrases.
Ironically, these are often the most important words in the document.
Words such as regional, national, economic, political, gradually, increasingly, expanded, and continued may not seem exciting, but they often contain the historical thinking embedded within the CED.
Consider the difference between regional interests and national interests. Or the difference between saying democracy expanded versus saying it rapidly transformed. Those small wording choices communicate important historical arguments about change, continuity, causation, and comparison.
I often tell my students that if the proper nouns provide the evidence, the descriptive language explains why that evidence matters.
This step slows students down. Instead of racing through the CED, they begin reading it carefully, paying attention to the historical claims embedded in every sentence.
This is my favorite question because it is the moment annotation becomes historical thinking.
After identifying the claim, students ask themselves a simple question:
"If someone challenged this Historical Development, what evidence would I use to prove it?"
Now they are no longer highlighting words. They are constructing historical arguments.
Each Historical Development receives two or three concrete examples drawn from the textbook, along with a brief explanation of how those examples support the larger claim. As students work through the year, they begin to see that evidence is not simply something to memorize for a test. Evidence exists to support an argument.
That is exactly what students will be asked to do on the AP Exam, whether they are writing an LEQ, responding to an SAQ, or constructing a DBQ.
This is the step students resist the most in August and appreciate the most by April.
Every historical example they add must include a textbook citation.
That may sound like extra work, but it serves several important purposes. First, it encourages students to return to their textbook rather than relying on whatever appears in an online search. Second, it creates an organized record of where each example was learned. Months later, when students are reviewing the Monroe Doctrine or the Seneca Falls Convention, they already know exactly where to find the material.
Perhaps more importantly, citing evidence reinforces one of the most important habits of historical thinking. Historians do not simply make claims. They support those claims with evidence from identifiable sources. This annotation strategy helps students begin developing that same habit long before they write their first college research paper.
One of the biggest misconceptions about studying history is that success comes from collecting more information. Students often believe they need more flashcards, more review videos, or another study guide filled with names and dates. Historical knowledge certainly matters, but AP History has never been about memorizing isolated facts. It is about learning how to use those facts to explain the past.
That is exactly what this annotation strategy is designed to teach.
Notice what students are doing as they work through the CED. They identify historical claims. They analyze the language of those claims. They search for supporting evidence. They document where that evidence came from. In other words, they are practicing many of the same habits historians use every day.
Over time, something interesting begins to happen in the classroom.
Students stop asking, "Do I need to memorize this?"
Instead, they begin asking, "What evidence could I use to support this Historical Development?"
That may seem like a small change, but it represents a fundamental shift in how students think about history.
Rather than viewing history as a collection of disconnected facts, students begin organizing information around larger historical ideas. Henry Clay is no longer simply a name to remember; he becomes evidence for debates over the American System. The Missouri Compromise is no longer simply an event; it becomes evidence for sectional tensions during the Early Republic. Every person, event, law, and court case begins to serve a larger purpose because it helps explain a broader historical development.
Perhaps that is the greatest benefit of using the CED this way. Students begin to see history the way historians do—not as isolated pieces of information, but as evidence used to support larger interpretations about the past.
After all, is that not exactly what we are trying to teach in AP History?
When my students first download the Course and Exam Description in August, many of them assume it is just another PDF that they will never open again.
By the end of the year, it is usually one of the most well-worn resources they own.
It is filled with highlights, annotations, textbook citations, and examples collected over months of reading, discussion, and practice. More importantly, it has become a living study guide—one they built themselves rather than one someone else created for them.
The AP Course and Exam Description was never intended to replace a textbook. It was designed to provide the conceptual framework for the course. When students learn to annotate it with purpose, they begin connecting Historical Developments to concrete evidence and, ultimately, to stronger historical arguments.
If you have never asked your students to work directly with the CED, this year may be the perfect time to start.
You and your students may discover what mine did: the most underused AP History resource has been sitting in front of you all along.
It is not the textbook.
It is the Course and Exam Description.
