What a 34-point pass line means: a score ladder from 40 sittings of pass-mark data

A 34 would have passed in 25 of 40 sittings, 62.5%. It sits exactly on the median. But the line has been higher lately. In the last 10 sittings the average pass mark was 35.6, and a 34 would have passed 3 times: both sittings in 2021, where it matched the line, and 2025, when the line was 33.

Each additional point changes the comparison. A 36 would have passed 37 of 40 sittings overall and 7 of the last 10. A 37 would have passed 39 of 40 and 9 of 10. 38 is the lowest score that reaches every threshold in this dataset.

Across the 40 sittings the line changed by a median of 2 points from one sitting to the next, and by 3 or more points in 12 of the 39 changes. The biggest swing was 8 points, between 1990 (26) and 1991 (34). The most recent was down 4, from 37 in 2024 to 33 in 2025.

For registration-training completers, who sit 45 questions, RETIO's table shows a line exactly 5 points below the general line in all 11 sittings from 2016 to 2025 for which it lists both. In 2025 that was 28 out of 45.

These are editorial suggestions, not RETIO guidance.

• 32 or below: below the 33–35 range TAC and LEC give; 31–32 is within U-CAN's 31–33 range, while 30 or below is below all three cited ranges. A pass would need a low line, which has happened but is not the usual case. Plan for a retake while you wait.
• 33–35: inside the TAC and LEC ranges. Do not read your number as a pass or a fail until November 25.
• 36 or above: above the top of all three cited school ranges. A 36 would have been at or above the line in 37 of 40 sittings.

Whatever your score, a self-score is only as good as the answer key behind it. The key is provisional until RETIO's official answers.
