In this talk, I will discuss the effect of disorder on a multi-band superconductor relevant to newly discovered iron based superconductors. I will describe various models of disorder and theoretical methods for including their effect on physical properties. I will discuss some phenomenological models of gap functions relevant to different families of iron based superconductors. These models are based on microscopic calculations with a spin-fluctuation pairing mechanism. I'll show how disorder can be used to extract information about the gap function from the experimental data.
