0.5% of those ADIs, who achieve 31 or more in the Standards Check, achieve 51 out of 51.
1.13% of those same ADIs, who achieve 31 or more, achieve 50 or 51.
3.2% of those same ADIs achieve 49, 50 or 51.
If the failure figures were included as well then these percentages would be far lower.
The figures have been taken from a Freedom of Information request, which produced a breakdown of scores obtained by ADIs in their Standards Check on a month by month basis between 7th April 2014 and 31st December 2014. The mean average of each score was calculated. This showed, for example, that an average of 4 ADIs each month scored 51; 5 ADIs scored 50; and 16 ADIs scored 49. An average of 36 ADIs each month scored 43 (Grade A) and 30 ADIs each month scored 42 (Grade B).
37 out of 51 was the most common score with an average of 62 ADIs gaining this each month.
Overall, an average of 28% of those ADIs, who passed the Standards Check, gained a Grade A.
