Language Academic Essay Evaluation Redesign

For an academic center: essays move from slow manual marking to AI-assisted scoring, with teachers only on unclear or high-stakes cases.
Disclaimer: Client and school identifiers, and student records, are sanitized where needed.
Project Summary

The Result: Feedback moved from 24 to 48 hours toward under 30 seconds on the fast path. About 90% of essays clear without a teacher touch. Active revision rose toward 85% (from under 10%).

The Problem: Essays arrived by email or forms, sat in spreadsheets, and waited for human markers to score four criteria by hand. Big score gaps needed a supervisor. Students waited 1 to 2 days for a PDF.

What we did: We redesigned marking so AI drafts scores for clear essays, and teachers only review unclear or high-stakes cases.

How essays were marked before: slow hand scoring, spreadsheet queues, and long student wait times.

The new path: AI drafts clear scores fast; teachers only step in on unclear or high-stakes cases.

4. How it works

Automation drafts scores for clear essays. Teachers stay in control of anything unclear or high-stakes.

System decides

  • Intake essays and prepare them for scoring
  • Draft scores across the four language evaluation criteria for clear cases
  • Release fast-path feedback when confidence is high
  • Route unclear or high-stakes essays to a teacher queue

People decide

  • Review unclear essays before scores go out
  • Handle high-stakes cases that need a human call
  • Resolve big score gaps that once needed a supervisor
  • Own the final mark when the AI path is not enough
