Pilot case study

A high-wage-market center saved tens of thousands — and got more accurate.

The clearest place to prove the value is where labor is most expensive. So we piloted PencilGrade at a learning center in a major, high-cost metro — the toughest test for a grading-cost story.

The center

A busy, paper-based learning center in an expensive metropolitan market.

👧~130 students

Across ~200 subject enrollments, several sessions a week — a real, full-volume center, not a demo.

💵High local wages

In this market, even part-time grading staff are costly — so grading was one of the center's largest line items.

📄All on paper

Worksheets graded by hand against answer keys, session after session — exactly the workload PencilGrade targets.

What changed

Two things moved at once: the cost went down, and the quality went up.

~$3,700
saved per month on grading labor
~$44,000
saved per year at this one center
99%+
up from ~92% by hand
grading accuracy

The cost side

→
Grading had been running about $6,750 a month — roughly half the center's wage bill, paid to part-time graders doing hours of repetitive checking.
→
With PencilGrade, the grading workload dropped by more than half. The center reclaimed roughly $3,700 every month — about $44,000 a year.
→
Those hours didn't vanish — they moved to teaching, feedback, and families, where they actually grow the business.

The accuracy side

→
By hand, grading in the center was accurate about 92% of the time — normal for tired eyes doing repetitive comparison work.
→
With PencilGrade assisting, accuracy rose to 99%+ — and it caught mistakes the human graders had missed, including answers wrongly marked correct.
→
That matters more than the money: a wrong answer marked "right" quietly advances a child who wasn't ready. Catching those protects the learning itself.
“Grading used to swallow our afternoons and our payroll. Now it takes minutes, we trust it more than we trusted ourselves, and my team is back to teaching.” — Instructor, pilot center

What it means at scale

One center in a high-wage market saved ~$44,000 a year. Multiply that across a region of paper-based centers and the grading line stops being a cost you tolerate — and becomes one you've solved.
