Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? Based on results of more than 25,000 teachers from 2017 to 2021, the mean expected score of a human trainee teacher on the CDPK benchmark is estimated at approximately 50%. → Lelièvre 2025

q2 · i? · design · r2
Estimation from aggregate subject- and year-level results of Chilean teachers on ECEP exams, allocating each benchmark question the average accuracy of its source paper; four methods all produced estimates around 50%. Question-level human results were not available, so this is an estimate only.
"Based on the results of more than 25,000 teachers from 2017 to 2021, the mean expected score of a human trainee teacher would be expected to be approximately 50% on The Pedagogy Benchmark."

Related Claims¶
- The benchmark procedure is stable under stochastic decoding, with a maximum accuracy standard deviation of 0.43% over 20 repeated runs — related
- Accuracy-cost value frontier: at $0.10 per million tokens, CDPK performance rose from 50% (April 2024) to 82% (June 2025) — related
- SEND and CDPK benchmark results correlate highly (r = 0.94), but higher-performing models do relatively better on general pedagogy than SEND — related
- LLM accuracy on the CDPK pedagogy benchmark ranges from 28% to 89%, with closed-weight reasoning models dominating the top of the leaderboard — related
