The home page.  The user sees a list of postings.  Ones that are theirs would be marked in a different color.  (Login system not depicted.)  Ones that are theirs also include reply information.  If it was not theirs, it would have an "Apply" link for candidates to apply.

This is my design which is supposed to be ultra safe. On the homepage there are sections in which you input desired classes, skills, or interests that you would like your student to have.  That populates the right side of the page in which you can get rid of any requirements if you accidentally make a mistake before you search for students.  The results page lists all the students that match all of your criteria, and clicking on a column corresponding to a requirement will sort the students according to how much experience they have in that requirement.  If you select the wrong requirement to sort by, you can easily fix that by clicking a different column and changing your sort mechanism.
