In response to a question (that may include an image) the respondent writes an answer in essay format. Three fields may be edited when creating the essay question: the question title, the body of the question, and feedback that can be displayed at a time chosen by the facilitator.
The essay question will not be assigned a grade until it has been reviewed by a teacher question, the grader will be able to enter a custom comment in response the respondent's essay and be able to assign a score for the essay.
Normally, the student can type their answer using the rich-text editor. However, if there is more than one essay question on a page, the rich-text editor is only used for the first essay question.
