Appropriateness

Evaluator last updated June 24, 2026.

Overview

The Appropriateness evaluator assesses whether a piece of feedback correctly identifies whether a student’s response has met the task goal and thus does not require further revision. The evaluator considers:

Accurate task assessment (whether the response meets the task’s relevant requirements)
Revision-need identification (distinguishing between feedback that should direct revision and feedback that should signal “move on”)
Appropriate signal when the task is complete (signaling the student can move on when the goal is met)

Input type	Teacher feedback on a student writing response
Supported grades	8–9
Rubric	Productive Coaching rubric developed by Quill.org ↗ and Leanlab Education ↗, in partnership with Anastasiya A. Lipnevich ↗

The evaluator was built and validated using the model and temperature below (other configurations will produce different results and may have lower accuracy):


Model used	GPT-5.4
Temperature	1.0
Optimization	DSPy + GEPA (Genetic-Pareto) prompt optimization against expert-annotated labels

Inputs

Input	Description	Required
Student text	Student’s written response	Yes
Feedback text	Teacher feedback to be evaluated	Yes

Example input

{
  "student_text": "Some people think AI-powered pets are a good alternative to real pets because they could help around the house etc.",
  "feedback_text": "You're right, the AI pets could help around the house. Can you find some other details from the article that you could add to make your claim stronger?"
}

Output

Field	Description
Appropriate feedback score	Binary judgment (1 / 0). A 1 applies when the feedback’s stance matches reality — it directs revision when the response doesn’t meet the goal, or signals “move on” when the response does. A 0 signals feedback that misses needed revision (telling the student they’re done when they aren’t) or asks for revision when the response already meets the task goal.
Reasoning	High-level summary of why the feedback received this judgment
Key features	One entry per factor driving the judgment (accurate task assessment, revision-need identification, appropriate signal when the task is complete), each marked met (1) / not met (0) with a justification
Proposed adjustment	Suggested moves to align the feedback’s stance with the task goal, for developers iterating on prompts or for teachers using the decision instructionally

Example output

{
  "reasoning": "The relevant task goal is to produce a claim with at least one relevant supporting reason or piece of evidence. The student does make a clear claim: AI-powered pets are a good alternative to real pets. The support given is that they could help around the house, which is a relevant reason, but it is very vague and weakened by \"etc.,\" so it does not function as sufficiently specific support on its own. That means the response still needs revision to meet the claim-and-support goal. The teacher feedback correctly recognizes the basic idea as relevant, but then clearly asks the student to add other details from the article to strengthen the claim. That is a clear revision signal and matches the fact that the student needs to revise rather than move on.",
  "key_features": {
    "accurate_task_assessment": {
      "met": 1,
      "justification": "The feedback treats the response as needing improvement, which matches the student text because the support is too vague (\"help around the house etc.\") to fully meet the claim-and-evidence goal."
    },
    "revision_need_identification": {
      "met": 1,
      "justification": "The teacher clearly signals revision is needed by asking the student to add more details from the article, which is the correct next step for this incomplete response."
    },
    "appropriate_signal_when_task_complete": {
      "met": 0,
      "justification": "This feature is not applicable because the student response does not yet meet the relevant task requirements, so a move-on signal would not be appropriate."
    }
  },
  "proposed_adjustment": "The feedback already meets the criterion. It could be even stronger by naming the problem more directly, for example: \"Your claim is clear, but your reason is too vague right now. Add one or two specific details from the article to explain how AI pets help around the house.\"",
  "appropriate_feedback_score": 1
}

Interpreting results

Output	How to use it
Appropriate feedback score + Reasoning	Evaluate whether your generated feedback is solving the correct problem. Validate that your prompts respond to actual student need rather than defaulting to a fixed stance (always affirm, or always find something to fix)
Key features + Proposed adjustment	Pinpoint and correct the specific failure mode. Require the model to assess whether the response meets the task goal before deciding to direct revision; target the specific failure direction
