The auditor scratches her head

New York's NAEP scores are in and there are puzzling differences with the state test scores, as this Edwize blog post notes.

Fourth grade reading and math scores for the New York State NAEP sample were flat or up slightly, yet our state tests showed 4th graders had declining scores in both subjects over the 2005-2007 period. Eighth grade reading scores (again for the NY State NAEP) were totally flat from 2005 to 2007 while the state tests show a gain of 9 percentage points over the same time period. Eighth grade math results were similarly flat on NAEP though they were up on the state tests.
 
In an earlier post <http://edwize.org/our-outside-auditor-is-about-to-report> , I said the NAEP results would  function as an audit of our state tests. Well, the auditor is perplexed. What  is going on between these two sets of tests to give such contradictory indications of our students’ progress?

This morning’s NAEP scores <http://nationsreportcard.gov/>  for 4th and 8th grade reading and math just tangled the picture as far as New York State’s achievement tests are concerned.
