2.1 Analyzing Primary & Secondary Sources

Why Source Analysis Decides Your Score

Of the roughly 35 questions on the GED Social Studies test, most present a stimulus — a passage, a document excerpt, a paraphrased summary, or an item scenario where two or three questions share one source — and ask you to interpret it rather than recall an outside fact. GED Testing Service calls this cluster of skills the Social Studies Practices (SSP), and three of the eleven practices govern how you read any written source no matter which content domain it comes from: SSP.1 (Drawing Conclusions and Making Inferences), SSP.2 (Determining Central Ideas, Hypotheses and Conclusions), and SSP.7 (Evaluating Reasoning and Evidence). Because these practices cut across Civics and Government (50% of the test), U.S. History (20%), Economics (15%), and Geography and the World (15%), weak source-reading skills cost you points on every domain, not just one. This is why the GED Testing Service's own Assessment Guide for Educators: Social Studies lists the Social Studies Practices as a separate assessment axis, layered on top of the content domains — every real test item is tagged with one content topic and one practice.

Primary Source vs. Secondary Source

A primary source is a document, artifact, or account created by a participant or witness at or near the time of the event: the Declaration of Independence, the U.S. Constitution, a Federalist Paper, a president's inaugural address, a Congressional debate transcript, a Supreme Court opinion (such as Brown v. Board of Education), a photograph, a letter, a diary entry, or a political cartoon published at the time. A secondary source is created afterward by someone analyzing, summarizing, or interpreting primary material: a textbook chapter, an encyclopedia entry, a historian's essay, or a modern documentary narration.

The GED frequently blends the two in a single item scenario: a short primary excerpt followed by two or three questions, sometimes cross-referenced against a secondary summary of the same event. (Comparing two treatments of one topic is its own tested skill, SSP.8 — covered in Section 2.4.)

SSP.1: Drawing Conclusions and Making Inferences

This practice has two parts: (a) determine the details explicitly stated in a source and make logical inferences from them, and (b) cite specific evidence to support that inference or analysis, attending to the precise wording of the passage. The GED almost never rewards outside knowledge on a source-based item — the correct answer must be traceable to the text you were given, even if you happen to know more about the topic from your own studies.

The classic trap is the "beyond-the-text" answer choice: a statement that is historically true and sounds authoritative, but is not actually supported by the specific excerpt on screen. If a passage about the Homestead Act says settlers received 160 acres after five years of residence, an answer choice claiming the Act "ended westward expansion" may be true-sounding but is not something the excerpt states or implies — eliminate it even if you recall it's factually accurate elsewhere.

SSP.2: Determining Central Ideas, Hypotheses and Conclusions

A passage's central idea is the main point everything else supports — distinct from a supporting detail, an example, or a piece of evidence. This practice also asks you to describe people, places, environments, processes, and events and the connections between them, and to judge whether new evidence in a follow-up passage corroborates (supports) or challenges (contradicts) a stated conclusion. A common item format gives you a paragraph and asks, "Which sentence best states the main idea?" — the wrong choices are usually true supporting details lifted straight from the text, which makes them tempting but too narrow to be the central idea.

SSP.7: Fact vs. Opinion vs. Reasoned Judgment

This practice requires telling apart three categories inside the same document: a fact is a verifiable statement ("Congress passed the Civil Rights Act in 1964"); an opinion is a personal judgment that cannot be verified ("the Civil Rights Act was the single greatest law in American history"); and a reasoned judgment is a conclusion that is backed by cited evidence and logical reasoning — not a bare opinion, because it rests on facts the author lays out, but not a pure fact either, because it is still an interpretation. The GED also frames this as distinguishing an unsupported claim from an informed hypothesis grounded in evidence — the informed hypothesis will point to specific data or quotations in the passage; the unsupported claim will not, even if it sounds confident.

How These Skills Show Up in Item Types

Multiple-choice items (four options) are the most common way source analysis is tested, but fill-in-the-blank items may ask you to supply a word or short phrase that demonstrates you inferred a vocabulary term's meaning from context, and drop-down items embedded in a passage are especially used to test whether you can select the logical conclusion a piece of text-based evidence supports.

Worked Example

"We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness. — That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed."

Stem: According to this excerpt, from where does a legitimate government's authority come?

Working it: the passage explicitly states government is "instituted" to "secure these rights" and gets its "just powers" from "the consent of the governed." An answer choice like "the consent of the people it governs" is directly supported (SSP.1a); a choice like "a monarch's divine right" is contradicted; a choice like "military strength" is a beyond-the-text distractor never mentioned in the excerpt at all.
