Overview
The Purpose evaluator assesses how clearly a text communicates its central purpose – whether it is to inform, persuade, explain, describe, or entertain. The evaluator analyzes whether a text’s intent is explicitly stated, indirectly hinted at, or masked (e.g., text may present as neutral information, but be building a persuasive argument).At a glance
The evaluator was built and validated using the model and temperature below (other configurations will produce different results and may have lower accuracy):

Interpreting results
High or low complexity scores are not inherently good or bad. A higher complexity score simply indicates a text that requires more interpretation by readers.Example: A “Very complex” or “Exceedingly complex” text may be ideal if
the instructional goal is identifying implicit or persuasive intent. However,
that same text may not be a good fit if the instructional goal is content
comprehension.
Accuracy and validation
This evaluator is provided as Early access. Comprehensive accuracy measures
are still evolving, and validation testing is ongoing.
Exceedingly complex texts aren’t common in lower grades and the benchmark
dataset doesn’t include many examples of them. Use caution when applying this
evaluator to higher grade levels where such texts are more frequent.
