Are parts of a pdf document in Adobe Acrobat Pro able to be secured so that once the recipient fills out a specific section, signs it, and submits it to the original sender, that information filled out is locked from editing for security purposes? If so,

I have an application I'm submitting to our school website for potential students to fill out. There are sections for the student(s) to fill out as well as sections for staff to fill out. For the sake of security for the student filling out the form, I'd like to set it up so that once the student has filled out the proper sections and submits the information, any information filled out and signed by the student is locked from editing on my part. I only need to read what the student filled out and signed, then add my notes to Staff sections.  Is this possible? If so, how?  I need details!
