## Overview

The Grade Level Appropriateness evaluator assesses whether AI-generated text is suitable for independent reading at a specified grade band.

The evaluator considers:

* Flesch-Kincaid grade level
* Word count
* Text structure – Organization complexity, connections between ideas, text features
* Language features – Vocabulary, sentence complexity, figurative vs. abstract
* Purpose – Explicitly vs. not explicitly stated, concrete vs. abstract
* Knowledge demands – Discipline-specific knowledge, references, allusions
* Student background knowledge – What students at a given grade level would already know

| **Grade + Reasoning**                      | Evaluate and improve the complexity of your AI-generated content<br /><br />**Example**: Validate that your LLM prompts produce grade-appropriate content; aggregate reasoning across runs to diagnose and fix systemic complexity issues |
| **Alternative grade + Scaffolding needed** | Adapt content for a wider range of learners<br /><br />**Example**: Make scaffolding suggestions (e.g., vocabulary pre-teaching, read-aloud) to help educators adapt content for mixed classrooms                                         |
