[quote=Anonymous][quote=Anonymous]Okay, this is now the third thread I am posting the exact same comment:

I'm a data scientist and the XLS spreadsheet of scores is a mess to parse. I have little confidence in the conclusions I'm seeing being drawn on this messageboard (not just this thread). Perhaps everyone else is better at this than me, but it is damn near impossible to figure out which columns sum to one another. Unless you can conclusively understand the data architecture (and summation is the first step), you should hesitate to draw conclusions.

I am interested in drawing lessons regarding Hardy and Deal from the PARCC data. I've failed so far. Give me some more time (hours or until tomorrow) to make some headway. But, in general, unless you honestly believe the poster completely understands the data structure (and my professional opinion is to be highly skeptical for this data set), you should cast aside the conclusions.

Did you ever reach any conclusions?  It seems to me that the data for PARCC results is intentionally presented this way so that smaller population groups (less than 25) cannot easily be isolated if not impossible to isolate.  This is the case at Hardy.  For example, not enough students took Algebra or Geometry at each grade level for us to see their scores and in the case of Geometry, not enough students took this class school-wide to even be able to see Hardy's overall success with Geometry.  Two hopeful conclusions can possibly be made:  1)  A least for Algebra, the scores appear to be high (not fair to compare to Deal since Deal has a much higher population size) and 2) Geometry is being taught at Hardy which is advanced for 8th graders.

If as others are saying, the feeder schools for Hardy are increasingly sending more students, perhaps soon we will be able to see test results in the more advanced math classes since all the feeder schools to Hardy are high performing schools.
