In regards to 6 month certification periods.I am fairly new to the world of eligibility ,it will be two years in January.I know our case loads have greatly increased since i came here and cannot imagine having to do renewals  every 6 months versus yearly.I will even go a step further and say i think you should stop requiring interims at 6 months and just do yearly renewals.This would put more responsibilty on the client and a little less work on the eligiblity  worker.
