One of the big issues administrators need to deal with are regular teacher evaluations. Having talked with many admins, this is a very time consuming part of their job and many use different systems to evaluate teachers. I think Evernote is a perfect tool for admins to use while making their evaluation rounds. Here is an example of how Evernote could be used by an admin for a teacher evaluation.
Evernote allows the user to create specific notebooks that store the notes users create. A notebook could be created for a specific teacher and notes on that teacher can be entered into that notebook. On the day of the evaluation, the admin can arrive a few minutes early and take some pictures of the class setup and save them directly into Evernote. The observation notes can be stored in Evernote and then later shared with the teacher before the follow-up meeting. A new note could be created and the follow-up meeting's notes could be stored and then later shared with the teacher as well. All of the information regarding the observation would be saved on Evernote and would be accessible from any device with the app or an internet connection.
