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. To use e-Rater for an assignment it must be enabled during the assignment creation.

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.
