Interview for nvq assessors job, what to wear?

[positively9something]

So I've got an interview for an nvq assessors job, I'm thinking black or grey pencil skirt and a shirt / blouse but what about shoes?

Normally I would wear court style heels but as it's so hot I'm wondering if lowish wedges would be acceptable?

Any other ideas on clothing?

Anyone?

I'm not sure on the clothes, is it at a college or a training company?
What exactly will you be teaching? I don't think there are such a thing as NVQs any more...

Hi sorry for the late reply, it is for a training company, it is actually a trainer and assessing role.

The subject I will be training and assessing in is business admin and sales

I'd probably go for a suit, but I don't know about shoes.

I don't want to be patronising but do you know about the qualifications you're delivering, saying you'll be assessing NVQs in the interview would be worse than wearing the wrong clothes!
