I have been doing this job for almost 15 years and have seen many changes and have experienced the increase in caseload size and way too many policy changes.  It is my opinion that we should leave 12 month certification periods with 6 month Interim Reporting in place.  Even if we see them more often it does not help us to decrease our error rates.  You will always have people who responsibly report changes whether you see them or they fill out a form and you will always have people who don't.  However, the ones who don't report changes are many times the ones who don't report changes even if you see them in person.  Going back to 6 month certification periods would only increase the worker's stress level trying to see that many more people in person.  Leave well enough alone.  People are going to be the people they are.  Some will be truthful and some not.  Changing the certifications period is not going to change that nor reduce errors.  Thank you for asking for our opinion.
