Early Release

This evaluator reflects early-stage work. We’re continuously improving its accuracy and reliability.
Take a look at the evaluator files.

​
What it is

The Grade Level Appropriateness Evaluator helps you assess whether AI-generated text is suitable for a given grade band. When you run a passage through the evaluator, it returns a structured output that includes:
  • Grade: The target grade band where the text can be read independently.
  • Alternative_grade: A fallback grade band where the text may still be useful with extra support.
  • Scaffolding_needed: Specific supports (like vocabulary pre-teaching) that make the text accessible outside the target band.
This gives you a clear signal about text difficulty and how it can be adapted, so you can generate content that matches learners’ needs.

​
Why it matters

One of the most pressing questions educators and edtech companies face is, Is this text appropriate for a particular grade level? Grade-level appropriateness is more than just a readability check. For edtech products, ensuring that AI-generated text aligns with the right grade band is critical for:
  • Educational accuracy: Students need texts that are neither too simple nor too advanced in order to build skills effectively.
  • User trust: Teachers and schools expect content that matches curriculum standards. Grade-level alignment helps your product earn credibility.
  • Personalization: With alternative grade bands and scaffolding recommendations, you can offer your users suggestions for adapting content to diverse classrooms where reading levels vary.

​
How it works

This evaluator will output the appropriate grade levels for the text. During the evaluation, the Grade Level Appropriateness Evaluator will conduct multiple analyses:
  • Quantitative analysis: Word count and Flesch-Kincaid grade level.
  • Qualitative analysis: Text structure, language features, purpose, and knowledge demands.
  • Student background knowledge: The background knowledge the student would need to comprehend the text.
It will then give you 4 pieces of information:
  • Target grade band: The text is appropriate for independent reading.
  • Alternative grade band: The text is appropriate for supportive reading (e.g., read-aloud).
  • Scaffolding: The scaffolding needed for supportive reading (e.g., pre-teaching of vocabulary).
  • Reasoning: A synopsis of the reasoning used by the evaluator to arrive at the grade level.
