<p>On the family section of the common app, I know my dad is alive and I know his name, but I don't know where he works or where he went to school. Should I just put unknown under parent type and also put down the information I know about him? Thanks guys.</p>
<p>Yes that information is most likely to help identify you and probably has little impact on whether or not you will be accepted.</p>
<p>Indicating “unknown” will allow you to move through this section without requiring the other information. If you do indicate unknown, then you might consider elaborating in the Additional Information section.</p>
