It's great to do a mid year evaluation. There is no requirement for such, but the more areas the company analyzes, the faster it will identify successes or areas that need further investigation. Analyzing how the company is doing with respect to established goals is great as it gives the company the opportunity to identify additional sources of recruitment, which is very important. If you can add adverse impact and perhaps compensation analyses, that would help the company identify & remedy any concerns sooner versus waiting for annual analyses.
