Forms as Skills Assessment

My immediate team uses Excel files for each team member to record a Skills Assessment. Where each team member self assess the "knowledge" and "execution" of a given topic. Leadership at large is interest in this for hundred of people rather than the 12 on our team. 

The request is to find a way to make the assessment a survey. Here is the issue, responses to the assessment should be directed to each person's manager and org chart. In other words, if I go an create the form, I will see all answers, and I am by no means qualified to have all that information. Is there a way around this other can duplicating the survey to each Group Director and having them distribute? If that is the route I am concerned about people making changes on their own and the difficulty of sending out updates if needed. 

Thanks!
