[quote=Anonymous][quote=Anonymous]It favors the poorly performing schools.  When you are at the bottom, the only way is to go up.

When you are at the top, there is no more growth and you are either stagnant or go down.

That is why the high performing schools with many more higher performing kids don’t have as good growth scores.  It doesn’t mean kids are not learning or doing well.

My kid scores 95-98% on math on standardized testing.  Highest percentile in group but terrible growth scores.  No surprises there.  Not much area to improve.

I don’t look at growth scores at all.  I look at the total percentages of kids above grade level to see if there is a cohort of kids and I look at total percentages of kids on/above grade level to see if that represents majority of kids (so at least grade level content can be taught).

It actually doesn’t conceptually or statistically favor poorly performing schools. It favors schools with the highest percentage of kids right at grade level and therefore best suited to be receiving the mandatory DCPS curriculum, especially in math where there are stricter rules about assignment adjusting. Additionally, all the evidence is that it’s hardest to grow the poorest performers, which makes sense: there are probably innate reasons they are performing poorly that are difficult to overcome (LDs).

But in practice, it’s lots of “good” schools (those with high performing kids) that have good growth metrics too. Take a look at the rich UNW schools.

My kids are at a CH school with a bimodal distribution and lots of 5th grade flight. Our growth scores are still decent: great teachers & parents of the high achievers are supplementing.[/quote]
