How the Criterion Service Works

Powered by the patented e-rater® engine, the Criterion service provides teachers supplemental feedback to help improve students’ writing skills — saving time and helping to enhance classroom instruction.

Get actionable feedback

Criterion provides holistic scores that closely align with human scores and that are specific to grade/level and measure overall writing quality. Furthermore, it gives diagnostic trait feedback in five key categories — grammar, usage, mechanics, style, and organization and development — which are used by the student to guide the revision process.

Easily gauge progress

  • Instructors create their own essay topics or select from the Criterion topic library.
  • Students write their essays online.
  • The Criterion tool automatically scores their writing and provides instant feedback.
  • Students use feedback to revise and resubmit their essays.
