There was a proposal put to TAC to lower the standard, not sure how it's progressing. However, as supply decreases and demand increases, it seems inevitable that NTA will come under pressure to devise a test with a higher pass rate. The current "Kathleen Doyle" test is widely viewed as an artificial barrier to entry. Of course, if all drivers were required to pass both modules of the test every 5 years it couldn't be viewed as such.
