Grading is eating your center's budget. It shouldn't.

At a busy learning center, grading worksheets is the single biggest controllable cost — hours every day of tedious, error-prone comparison. PencilGrade uses AI to give your graders that time back, and get the marks right.

How PencilGrade works

A quiet speed-assistant beside your grader — the student's experience never has to change.

The problem every instructor knows

The teaching is the easy part. The grading is what burns the hours and the payroll.

$It's the biggest cost you can control

Grading can be roughly half of a center's wage bill — paid mostly to part-time staff doing repetitive comparison work, sheet after sheet, every session.

It's slow

Every page is checked against an answer key by hand. Students wait. Lines form. Instructors get pulled from actual teaching to keep grading moving.

It's error-prone

Tired eyes miss things. A wrong answer marked correct quietly advances a child who wasn't ready — the exact opposite of what the program is for.

A smarter way to grade

PencilGrade is an AI-powered assistant that sits quietly beside your grader.

It reads a student's completed worksheets and, in seconds, tells your grader exactly which answers need attention — so a task that took hours takes minutes, with fewer mistakes. Your grader still hands the child a human-marked sheet and works with them to 100%, exactly as today. The student's experience never changes — the grader just moves at a different speed.

Why centers choose it

It protects your program's routine. Results go to the grader, never the child. Kids still receive a human-marked sheet and work to mastery — the human touch that makes the method work stays intact.
It's instant and on paper. No next-day turnaround, no screens for young learners. The teachable moment stays in the room.
It surfaces struggling students. When a student trips a set error threshold, PencilGrade flags it for the instructor — turning grading into an early-warning signal, not just a chore.
It frees your best people to teach. The hours reclaimed from grading go back into instruction, feedback, and families.

Give your graders their time back.
