The proof
The results are on the record.
Principal Ready is built on the teaching methodology, powered by the Built To Pass framework, behind more than 70,000 passes. Here are the independent numbers, in full, so you can judge them for yourself.
Independent research · HumRRO, 2025
Twice the first-attempt pass rate. On the record.
HumRRO’s 2025 independent study compared the courses Dr. A built and led as founder of The Learning Liaisons against the major competitors in the field. The numbers below come from that study.
First-attempt pass rate
0×
Higher than the major competitors
Margin on 1st attempt
+0pts
First-attempt pass rate, head-to-head vs. competitors
Course engagement

Reported pass rate for course completers
From a pass-tracking system Dr. A built at The Learning Liaisons that followed course participants all the way to test day, then collected reported pass rates from test-takers. Separate from the HumRRO study above.
