My district is infected with the data disease; way more data than I have time to crunch, or really need. Most of it tells me what I already know.
The only data I've requested on a regular basis takes an act of district congress to get; that's data on students in my class over time.
When we've finished another round of testing, I want results that will tell me RIT and percentile, overall and for strands, for the last 3 testing sessions, with the most recent added on.
I can print up floods of pretty color graphs for each student, and for my class as a whole, for the most recent test. As a matter of fact, my inbox was flooded with reams of the stuff all year long, which I promptly shredded. Getting longitudinal data on each student in my class (on one report, not 32 separate reports) is challenging, and, by the time I get it, it's no longer useful. It can take months.
A lot of the data is useless to me. I don't care about their DIBELS fluency scores, and I wish the powers that be would quit trying to convince primary students that "fluency" = "speed." I get 6th graders that have been trained to read aloud as quickly as possible, passing over all punctuation and paragraph breaks, to try to up their "wpm." The idea that they ought to use punctuation and expression, to make meaning out of the words, is foreign to them.
It takes me all 3 years, 6th - 8th, to undo the fluency programming and get them to read as if the words meant something.
Edited to add: While you're at it, do you want to weigh in here, as well?
