I remember a long time ago we were looking for a new piece of software at the school district and we got into this huge debate about what defines student achievement. There were a wide array of varying opinions and this kind of feels like that. Like many things, I think it is subjective. I've seen people living in squalor who are happy as clams. Mentally their well being is great. Physically, probably not so much. Either way, I think this is a solid addition to your community as a subtopic.
Yes. It is subjective to a high degree in detail, and there are caveats that would change potential, but at a base level, we all are pretty much the same.
Was consensus reached on what defines student achievement?
No, but we didn't finally pick a piece of software that was supposed to measure it!
That might actually be a good thing. Considering the software would end up being "the truth" and it will probably be flawed :D
It's basically just an assessment delivery system.
