Supply your answer key and Digital Red Pen grades each student's handwritten work to your exact solution — aligned to your standard, with a per-skill breakdown across Six Teachable Items, math practices, and item analysis. The teacher still reviews every grade and makes the final call.
Keyed Grading
Grade to your exact solution.
Get the skill breakdown.
Give it your answer key. The grader aligns to your solution, reports which skills each student has and doesn't, and surfaces every grade for your review before any report leaves the system.

What the skills breakdown shows
Six Teachable Items
Every problem tests one or more of six math skill types. The breakdown shows which items each student has and which are gaps — by student and across the class.
Math practices alignment
Standards for Mathematical Practice mapping across each problem — useful for standards-based grading and parent communication.
Item analysis
How each question performed across the whole class: difficulty, discrimination, common error patterns. Know before the next lesson which problems did the teaching work.
Per-student reports
Each student's graded exam with skill-level feedback tied to your key — so the report tells them not just what was wrong, but what kind of thing was wrong.
Frequently asked questions
What is the difference between keyless and keyed grading?
Keyless grading requires no setup — you upload your student stack with a clean copy of the test and the system infers the solution. Use it when you want grades tonight with no preparation. Keyed grading uses an answer key you supply or author; the grader aligns to your exact solution and standard, and reports a deeper per-skill breakdown. Use it when you want your specific solution reflected and richer diagnostic data.
What does the skills breakdown show?
Keyed grading reports per-skill performance across multiple schemas: Six Teachable Items (the six types of math skill a problem can test), Standards for Mathematical Practice alignment, and item analysis (how each question performed across the class). You can see which skills your students have and which they don't — before the next assessment.
Do I still review and approve the grades?
Yes. Every grading run goes through The Desk — the built-in teacher-review layer. You review each grade, override anything you disagree with, and approve the report before it goes anywhere. Rulings propagate: one correction applies to every matching case in the stack. Nothing reaches students until you approve.
Do I need to author the answer key myself?
No. You can supply any existing answer key, or use exam authoring — upload your master test PDF and the system generates a structured key from it. That key then feeds directly into keyed grading.
Is keyed grading more accurate than keyless?
The system aligns to your specific solution and standard, which adds depth and consistency. A controlled accuracy comparison between keyed and keyless has not been run, so no accuracy-gain claim is made. What keyed grading adds is alignment to your exact key and richer per-skill diagnostics.
