4%

All initiatives to improve diversity of employment on and off screen at the BBC are welcome. And obviously, it's good sense to set targets that are achievable.

In January last year, Acting DG Tim Davie published the last big diversity report. Auntie had already recognised the problem of getting black and Asian minority ethnic recruits into senior management. So a new target area was constructed, of "senior level management", which included staff on Grade 10, Grade 11, as well as the real Senior Management grades, SM2 and SM1. 7% was to achieved by 2012 - and in September that year, it stood at 6.5%.  Tim set a new target of 10%, to be achieved by 2017.

Lord Hall's announcement seems to vary the reporting group again, talking about "grade 10 to SM1... in the most relevant areas of TV and Radio Production, Broadcast Journalism and Commissioning and Scheduling."  He says it's currently 8.3%, and he's added a stretch target beyond the 10% by 2017 - aiming for 15% by 2020.

Of course, when reporting "senior management" to MPs and the Mail, the numbers are restricted to SM2 and SM1 grades (though the growth in Band 11 jobs over the past five years has not gone unnoticed).

I think it'll be interesting to monitor the diversity of those BBC employees who are in real "leadership" positions - such that, for the glory of the job, they have to agree to have their salaries and expenses published.

They are exactly 100 on the current list. I can't find photos for Kieran Clifton (Mr Marina Hyde), Rachel Currie, Richard Payne, Gautam Rangarajan, John Turner and Cary Wakefield, but am prepared to take a wild guess that only one might bother the BAME Diversity Jury.  And thus I estimate a total of 4 out of 100 as we stand.

• One of Tim Davie's SMART objectives was to get the BBC listed in Stonewall's Top 100 gay friendly employers chart by December 2013.  Can't find them in the list for 2013, or 2014.
