NudgeLearn Grader docs
Updated 19 September 2026
One page per task. Each one says what to click, what the limit is, and what happens when the step does not work, in the words the product actually uses on screen. Where a behaviour has a cap, a refusal or a case it cannot handle, the page names it rather than leaving you to find it on a stack of thirty. Nothing here is a product tour: if you want to know what the grader is before deciding whether to use it, the tour and the FAQ do that job, and our measured agreement with official examiners is published in full. A free account grades 20 items, so every step below can be tried before anything is paid for.
Setting up
Done once, and everything else gets easier afterwards.
- Connect Google Classroom to NudgeLearn Grader
Where the Connect button is, what Google asks permission for, and the six steps from course to graded.
- Connect Canvas to NudgeLearn Grader
Canvas takes a pasted web address and a personal access token. Where to make one, and what gets checked.
- Add students to a class
One at a time, or paste a column from your gradebook. What is skipped, and the row limit.
- Build an answer key for an assignment
One blank copy builds a key you can edit. It does not count against your graded items.
Getting the work in
File types, page limits, and the things that stop a batch starting.
- What you can upload for an essay
Every accepted file type, and the Google Docs sharing setting that a link needs.
- The Grade button is greyed out, or nothing happens
Five conditions keep the button disabled. Here is the whole list and what clears each one.
- One essay per file, and the 8-page limit
One file is one student. A longer PDF is refused by name rather than silently cut short.
- Split a scanned class stack into one paper per student
Say how many pages each paper runs and the stack splits in order. Plus the page ceiling.
Getting the grades out
Into a gradebook, by sync or by file.
- Send grades back to Google Classroom or Canvas
What gets sent, what gets skipped, and the Google rule that refuses some assignments.
- Export grades as CSV
Two exports, their exact columns, and what a blank cell means in each.
Changing and removing grades
After the first pass, including what a second pass costs.
- Re-grade a paper after changing a rubric or key
It bills again, it overwrites your edits, and the score can move. Restore is free.
- Delete graded student work
One paper, a selection, or everything matching a filter. What goes with it.
Not a task, but often the next question
- How accurate it is, measured against official examiner scores, with the method and the limits
- What a graded item is, and what each plan includes
- The rubric library: 86 state and national writing rubrics
- How handwritten work is read, and what happens when it cannot be read
- Honest comparisons against the main alternatives, including where they beat us
