At our facility, we have to be certified for MDS, which involved a 3 day course and two exams taken within 3 months of the course, with a result of 85 percent. Each year, we are expected to re-certify MDS yearly. The data users enter is used to determine funding and staffing levels for LTC's, so users are expected to be competent. I would ask your facility what they're plan is for this training because it's crucial that you understand what you're doing with MDS. Also, I would recommend that you spend at least a month on the floor first, so you can start to learn the residents. Regardless of what your superiors may say, you can't code accurately if you don't know the residents and their plan of care. Just my thoughts.
