Justice, Testing and Ratings

Yesterday I made reference to the fact that 65% of a CPS school's rating is based on a composite of test scores. I stand by calling this a sham not merely based on it being an arbitrary number but because of compelling evidence that the success enjoyed by students lies well outside of the testing regime and by association any 'teaching to the test.'

Plenty of studies are available that point to the influences affecting the level of student success. By most accounts some 2/3's of what influences the learning of any student are those which take place outside of the school building. That being the case here is but one question I'd like to pose. Can those who have come up with this arbitrary 65% figure tell me to what extent they have taken into account the significance of these outside influences?

My best guess is they can't and that's all the more reason to dispense with the 65% number of any such figure.
