These spreadsheets document the academic outcomes at the most recent additions to the SPS building inventory and compares them to peer schools receiving lower MGT “educational suitability” ratings*.

You will easily discern that neither Harrison nor Hickory Hills have either consistently or significantly out-performed their peers.  In fact, there is no discernible advantage for either.

You will also see that the first year at the new Sherwood, the last year appearing in the data, did not improve that school’s scores vis-à-vis its peers.  There was actually a slight decline.

Finally, the three years of results for the new Westport, both at the elementary and middle school levels, demonstrate a substantial negative trend.  This is in a configuration, the “co-located” K-8, which is scheduled for three additional sites in the current proposal.

We believe that creating such high-poverty mega-schools is, more likely than not, injurious to student achievement.

(*The numbers alongside each school name are the MGT suitability scores.)

Please note that comparing year-to-year scores of the same school is misleading due to occasional changes in the composition of the MAP test.  It is through comparisons of demographically similar schools that the relative proficiency of a given school is best revealed.

For example, in the comprehensive database of scores from all schools, it is more productive to view results vertically and for the same year than horizontally for one school over several years.  However, in the various targeted school-to-school comparisons, it is preferable to examine the performance of each school in the context of the performance of its peers by means of the horizontal same year data.
