Thanks for posting those ACTUAL statistics yimke.
Sort of like military flight school washout rates, the CFI pass rates tend to grow more dire with every passing tale.
I'll bet that a DPE or an ASI with a passing rate of less than 50% would be getting a hard look from the higher-ups; the same as would a DPE or ASI with a 99% pass rate I imagine.
