evidence: Our research found that chief constables in those 15 forces remain in post for a mean average of 5.7 years. For forces in England and Wales specifically, the average tenure was 5.8 year. PSNI chief constables have stayed in their role for 5.2 years, on average. Based on those comparisons – with a gap in average tenure of under half a year – it’s fair enough to say that "the average tenure of a PSNI Chief Constable is about the same as those in England and Wales". [...] The average tenure of a chief constable of the PSNI is 5.2 years: Hugh Orde (7.0 years), Matt Baggott (4.8), George Hamilton (5.0), Simon Byrne (4.2).
