What this skill is asking
The extended writing response is the essay in Section 1 of the Georgia Milestones American Literature and Composition EOC, and understanding what it asks is the first writing skill. It is source-based: you read two passages, then write an essay that draws and cites evidence from them, not a stand-alone opinion piece. The prompt sets the mode (usually argumentative or informational/explanatory), and the whole essay is scored on a seven-point two-trait rubric. This page covers the nature of the task, how it differs from a personal-opinion essay, the modes, and how it is scored. The transferable skill is reading the task as a contract, write from the source, in the mode the prompt names, toward the rubric, so you do not waste effort on an essay the task did not ask for.
A source-based task, not an opinion essay
The defining feature is that the essay comes from the passages.
The most common misconception is that the essay is a general-opinion piece on the prompt's topic. It is not: it argues or explains from two specific passages. This is why reading the passages well, the comparing-and-synthesizing skill, feeds directly into the essay. A reliable first move is to read the prompt, identify the mode, then read the passages hunting for the evidence you will use.
How it is scored, and what that means for you
Knowing the rubric tells you where to spend effort: most of it on the controlling idea, evidence, and organization (the 4-point trait), with time reserved for a proofread (the 3-point trait). The essay is a true extended task that takes real time to plan and write; in this site we describe writing-task knowledge in prose and cap any single practice item's marks at the genuine raw tariff (the rubric runs 0 to 7), rather than inflating it.
Reading the task as a contract
Try this
Q1. What does it mean that the extended writing response is "source-based"? [Recall]
- Cue. It means the essay responds to two passages you read in Section 1, and its evidence must come from those texts, not from outside opinion or invented examples, so the essay argues or explains from the source.
Q2. Why does a fluent essay that ignores both passages score poorly? [Short explanation]
- Cue. Because the idea-development trait rewards specific, relevant evidence from the passages; an essay that never refers to them leaves that requirement unmet, and fluency or clean grammar cannot replace the missing text evidence, so the larger-weighted trait suffers.

GA Milestones Am Lit (EWR)4 marksExplain what makes the extended writing response 'source-based' and how that changes how you write it, compared with a stand-alone opinion essay. (Knowledge of the task; the essay's idea-development trait is scored 0 to 4.)Show worked answer →
Source-based means the essay responds to two passages you read in Section 1, and your evidence must come from those texts, not from outside opinion or invented examples. This changes how you write: you read the passages first, find evidence that supports your idea, and cite or paraphrase it, so the essay argues from the source.
Compared with a stand-alone opinion essay (which invites your own examples), the source-based essay rewards specific, relevant text evidence. The idea-development trait (0 to 4) rewards drawing on the passages, so an essay of general opinion that ignores the texts cannot score well, however fluent.
GA Milestones Am Lit (EWR)3 marksA student writes a fluent essay on the prompt's topic but never refers to either passage. Why will this essay score poorly, and what should the student do instead? (The full essay is scored on a seven-point rubric, 4 for ideas plus 3 for conventions.)Show worked answer →
It will score poorly because the response is source-based: the idea-development trait rewards specific, relevant evidence from the passages, and an essay that ignores them leaves that requirement unmet. Fluency and clean grammar cannot replace evidence from the texts.
Instead, the student should read both passages, build a controlling idea, and develop it with evidence drawn and cited from the texts. The whole essay scores on the seven-point rubric (Idea Development, Organization, and Coherence, 0 to 4, plus Language Usage and Conventions, 0 to 3), and ideas carry the larger share.
