This goal tracker is a similar version to one made by an adviser from the Khan Lab School. It's very functional for as many students as you have.
If you have a lot of students to track, I suggest making a copy for each of them, sharing with each student individually, and storing all the Sheets in the same Google Drive folder. And you might want to share the whole folder(and every Sheet in it) with teachers in your school, allowing access to view and comment(for encouragement) on student progress.
To access the file, open the .pdf and click on the Google Doc link. When the Sheet is open in your browser, click on "File" and then "Make a copy." Then it's yours to edit and share.
