* A search function: Most online faculty lists or school websites have a search bar where you can type in the principal's name or title ("Principal").
* Alphabetical ordering: If the list isn't searchable, it's likely alphabetized by last name. You can scan the list to find the principal's name.
* The school's website's "Administration" or "Staff" page: This page is often organized to clearly list administrators, including the principal.
* A school directory: Some schools have printed or online directories listing all staff and their contact information.
The best aid will depend on how the faculty list is presented.
