The Herald capturing the news in 2016 but somehow missing it in 2019

The number of school inspectors available in Scotland has increased steadily and is now 23% higher than in 2012 after a year of staff retirements.

As might be expected, the number of inspections in 2018/19 has increased in line with this and, in the last year, increased by 23%
