One thing I've had to do a few times is what we call a 360. It's basically where your colleagues and/ or subordinates are interviewed about your strengths and weaknesses. The results are then collated together, anonymised and given to you to digest.
It's sort of like an affirmation but without the all-important 'don't include anything negative!'
It's not always a pleasant experience, but it's usually a useful and growthful experience. If people are honest and balanced and if you're prepared to take it all on board, then it can really be something that sharpens your practice nicely.
Anyway, I mention this because I've just been reading a piece from a few weeks back on MoreThanDodgeball.com. A youth pastor (you have to negotiate the evangelical language) created an evaluation sheet for himself and made it available for others to use. You can read about it and download it here.
If you know of any more resources around this area, let us know and we'll post those too...
