Here is an article from ED Week regarding student data databases and their uses. A quote:
Years ago when teachers, administrators and school staff were looking to build early warning systems to catch children from falling through the cracks, they would keep attendance records, grades and whether the students were tardy or leaving early on a regular basis. Now with accountability, and issues of Teacher of Record (TOR), schools are tracking students in every way possible so they can maintain an electronic paper trail. Numbers are not always the problem…it’s what people do with the numbers that can sometimes pose a problem.
