The update would include recent employment. At my current job I am responsible for training new employees and closing up shop at the end of the shift. Also there has been what I would consider a significant change in our family structure. My grandfather who was recently discharged from a 3 month stay in the hospital has come to live with my family. He requires around the clock care in which I have been assisting with.Updates to your application must be verified by a school official or must be independently verifiable (e.g., certificate, letter from organization, etc.). For items that have official letters or certificates from the organization or are otherwise verifiable on their face, submit copies of those. If you have new items that don't fall into that category (e.g., being elected team captain or president of a club) type them up, have your school official endorse them (the same one who endorsed your original activities record works) and then send by email or snail mail to your RD.
Note that new items should be "significant." That would include things like attaining Eagle Scout, receiving a merit scholarship, being elected to a school or club office, making varsity in a sport, being elected team captain, etc. Things such as joining a new club aren't going to make much difference. If in doubt, go ahead and send them in -- it won't hurt.

They may eventually ask your employer how you are at your job (rating things such as your cooperativeness, alacrity, and other factors...)
