I Got A K

I had my annual performance review from my boss today. In the past performance targets were given by "Exceeds Requirements", "Doesn't meet Requirements" and "Meets Requirements" - otherwise known as the thumbs up, thumbs down or shrug. OK they weren't really known as that..

Anyway, now those definitions are gone, replaced with an incrementing scale of goodness from I to K... which goes like this: I, P-, P, P+, K.

My boss, who I could subtly infer is a cool guy but I'll just get out of the way and state it, gave me a K overall this year. I think this is partly because he knows I've been doing a lot of work for a lot of clients in the middle of a two year (and counting!) pay freeze, but also because he's as curious as me about what a "K" actually is. It doesn't say it on the review forms anywhere, and in all the excitement to invest money in a not-broken system they forgot to mention it.

So, anyone who feels like a comment, what do you think a K really means?

Here's some K's for inspiration:
