Everyone sends cards to PSA. Nobody teaches you how grading actually works.

💰

Expensive blind submissions

At $19-350+ per card, submitting to PSA or BGS without knowing what grade you'll get is a gamble. One wrong pick and you've paid $25 for a card that comes back a 6.

Months-long wait times

Standard PSA turnaround can stretch for weeks or months. If you could accurately pre-grade your own cards, you'd only submit the ones worth the wait.

📚

No structured education

Everything you know about grading comes from YouTube videos, Reddit threads, and trial-and-error. There's no curriculum, no certification, no proof of knowledge.

🤝

Trust gap in local markets

At card shows and local sales, buyers rely on trust. A recognized grading certification gives dealers credibility that a business card can't.

Three tiers. One certification.

Master the same four criteria the pros use: centering, corners, edges, and surface.

Level 1
Foundations
  • The 1-10 grading scale across PSA, BGS, CGC, and SGC
  • Understanding centering ratios and how to measure them
  • Identifying corner and edge wear at every grade level
  • Surface condition: scratches, print lines, and whitening
  • When a card is worth submitting and when it's not
Level 2
Standards
  • How PSA and BGS grade the same card differently
  • Subgrades explained: what BGS 9.5 vs 10 really means
  • Practice grading with real-world card examples
  • Predicting grades within half a point accuracy
  • Maximizing resale value through strategic submission
Level 3
Expert
  • Vintage card grading: tobacco, pre-war, and classic era
  • Authentication red flags and counterfeit detection
  • Error cards, variations, and special designations
  • Building a grading-focused business or side income
  • Final certification exam and GradeSchool credential

Built for the hobby.

Collectors who submit cards

Stop wasting money on cards that come back lower than expected. Learn to self-assess before you ship, and only submit cards with real upside.

Card shop owners and employees

Your customers ask about grades every day. A certified team builds trust, drives sales, and positions your shop as the local authority on condition.

Card show vendors and flippers

Buying raw cards at shows is where the margin is. If you can accurately grade on the spot, you spot the deals everyone else misses.

New collectors entering the hobby

The difference between a PSA 9 and a PSA 10 can be thousands of dollars. Understanding grading fundamentals protects you from day one.

The $4 billion grading industry has no school. Until now.

GradeSchool is building the first structured certification program for trading card grading. Professional knowledge, accessible to everyone in the hobby.
