Frequently asked

Do I need my school's approval to use AI grading?
For pilots on your own students, most districts require at minimum a data-processing review. Share the vendor's DPA and FERPA statement.
Will students know their work was graded by AI?
Best practice is disclosure. Every tool we recommend supports a teacher-review step so the final grade is yours.
