Assessment Grading App for Teachers
The fastest way through the pile.
Scan a class set, mark question by question, and walk away with scores, comments and analysis — in one sitting.
Fewer taps. Faster marks.
Every tap the app can save you, it does.
One question, every student.
Mark Q3 across the whole class in a row. Faster, and your marking stays consistent from the first script to the last.
Tap a number, not a form.
A score keypad lives next to every answer. Score without leaving the page, then the next answer slides in.
Comment without typing.
Reusable snippets, stamps and dictation. Say it once, apply it to every script that needs it.
Nothing is ever lost.
Every edit saves instantly on your iPad. Works fully offline, and anything deleted is recoverable for 30 days.
Template authoring
Map the paper once. Mark it everywhere.
Map the questions on a blank paper and every student's script inherits the structure — regions, marks, rubrics and all.
The marking suite
Everything a red pen does. Faster.
Tick, annotate, score and comment without ever leaving the script.
Assessment analysis
Analysis that does its own homework.
In-depth analysis generated as you mark and exported as you like.
Collaboration
Mark together. Agree together.
Share sets, split the questions and moderate each other's marking — across the department, or across a whole trust.
Nib for students
No paper. No scanning. No peeking.
Using our unique assessment mode where students' iPads are locked down to sit your assessment, and submit straight to yours.
Import. Mark. Export.
