What it grades
Four kinds of answer. Every kind of assignment.
Your answer key tells it what each question is. It grades each one the way a teacher would.
Multiple choice
Circled, ticked, bubbled or written — the chosen letter is read, even when the student changed their mind and crossed one out.
Numeric
Compared as a value, not a string. Fractions, decimals, scientific notation and units all match — and a tolerance on the key marks a range.
Short answer
One mark per distinct idea, never the same idea twice, and a student's own valid example counts. Two things are yours to set: whether wording must match the key's term, and whether spelling counts.
Essay
Judged against named criteria you can read before grading — Common Core writing standards ship built in, or paste your school's own rubric — and reported back per criterion.
Every format
Whatever you assign.
Photos (including iPhone HEIC), PDF, DOCX, DOC, PPTX, XLSX, XLS, ODT, ODS, IPYNB, Pages, Keynote, Numbers and plain text. The full list →
When it isn't sure
Flagged for you, with the reason.
A crossed-out answer, an ambiguous digit, a blank — the question comes to you next to the photo of the student's work instead of being silently scored.
Q7 · Diego Torres
Two answers written, neither crossed out — "12" and "21". Your call.
Your scale
Your school's grades, not ours.
Pick the scale, set the boundaries and the pass mark, and every export follows it.
