e-rater® Grammar Check Technology

The e-rater grammar feedback technology, developed by ETS®, automatically checks submissions to an assignment for grammar, usage, mechanics, style and spelling errors; providing in depth feedback with on paper marks. 


Note: There is a 64,000 character limit for ETS e-rater checking. Papers in excess of this limit are not eligible to receive grammar checking.

When is e-rater® feedback released? 


e-rater® grammar and spellcheck comments are automatically available to you immediately after submission.


Note: It may take up to a minute for the e-rater feedback to load onto the paper.
