I agree that, if you assess ability, you should do it across grade/experience. However, past work experience is surely a better predictor of future performance than a generic test?? I think it's a great way to assess graduates as it tests raw ability. However, wouldn't it be much better to use case studies or the like to challenge someone with experience?? If ability tests are to be used, presumably it's just to ensure candidates achieve a certain standard??Just asking so, don't get too defensive :0)
