In a poetry essay, evidence is more than a quotation dropped into a paragraph. It is the foundation of every claim, and the way a student selects and handles it reveals how well they understand the poem. Duffy's compressed style makes this especially important, since a single word can carry a great deal of meaning. Teachers who grade evidence use carefully can diagnose problems that otherwise hide behind confident prose.

The first thing to check is length. Students who quote whole stanzas often avoid the harder task of choosing the most revealing phrase. Shorter quotations force them to focus, and they make it easier to analyze individual words and sounds. When marking, reward essays that select brief, precise evidence and penalize those that rely on large extracts without commentary.

Next, examine how the quotation is integrated into the student's own sentence. A well-embedded quotation reads smoothly and supports the point being made, while a poorly integrated one interrupts the flow and leaves the reader unsure of its purpose. Feedback can model this by showing how the same quotation could be woven into a sentence more naturally. Small stylistic changes often improve both clarity and confidence.

From quotation to analysis

The most important question is what the student does after quoting. Many essays stop at identifying a technique, saying that a phrase uses alliteration or a metaphor. Stronger essays explain what that technique contributes to the speaker's tone, the poem's mood, or its larger argument. A useful comment is to ask the student what the reader feels or understands because of the choice, and to write that explanation in the next sentence.

• Selects short quotations that directly support the claim
• Embeds evidence smoothly within the student's own sentences
• Zooms in on individual words rather than whole lines
• Explains the effect of the technique, not just its name
• Uses evidence from across the poem, not only the opening stanza

Spotting patterns that need intervention

Evidence problems often show up as patterns across a class. Perhaps many students quote only from the beginning of the poem, or rely on the same two or three lines. Noticing this tells you where to focus teaching, such as a lesson on how a poem develops across stanzas. Marking can feed directly into planning when you track these trends.

Pay attention too to evidence that is accurate but not relevant. A student may choose a well-known line because it is memorable, even though it does not support the point being made. Feedback should ask them to check whether the quotation truly matches the claim. This habit of testing evidence against argument is central to all academic writing.

Efficient assessment of evidence

Because evidence appears in every paragraph, assessing it thoroughly can be time-consuming. One approach is to grade only evidence on a first pass, highlighting each quotation and marking it as effective, adequate, or weak. This gives you a quick overview of the student's approach before you consider other criteria. AI tools like GraideMind can support the process by identifying quotations and flagging where analysis is thin, leaving the final judgment to you.

When giving feedback, choose one or two examples from the essay rather than commenting on every quotation. Praise the strongest example and explain why it works, then suggest how a weaker one could be improved. This approach is easier for students to absorb and produces more lasting change. A focused comment is usually more effective than a dense page of annotations.

Teaching evidence skills directly

Consider short, low-stakes exercises that isolate evidence skills. Ask students to find the single most important word in a stanza and explain why in three sentences. Or give them a paragraph with an overlong quotation and have them cut it down. These activities build habits that carry over to full essays.

Use your own marking to build a shared vocabulary around evidence. Terms like embed, zoom in, and explain effect become familiar when you use them consistently in feedback and in class. Over a term, students begin to apply these ideas without prompting. The result is stronger, more confident analysis across the board.
