After students complete a district test, many teachers receive access to data-rich spreadsheets detailing student performance across standards. The problem is, it takes a bit of work to group students based on these standards. Since in a former life I was a computer programmer, I created a utility to automatically group students from these spreadsheets: The Student Grouper.
Update 10/24/10: The Student Grouper has been reborn and no longer requires an Excel upload. Simply copy and paste your Excel data into the text area.
