Non-parametric trend analysis of SCASD PSSA performance Methodology
bull Review Pennsylvania System of School Assessment (PSSA) math and reading scores from AY 2001-2015 (public schools only)1 The original data sets2 are found at httpwwwpdestatepausa_and_tcwpbrowseaspa=3ampbc=0ampc=27525ampa_and_tNav=|633|ampa_and_tNav=|
bull Rank the percentage of students who were classified either ldquoproficientrdquo or ldquoadvancedrdquo at each grade level3 in descending order Thus a lower rank indicates better performance relative to other districts

1 The analysis was restricted to this millennium PSSA data are available prior to 2001 but PDE did not summarize them
at the district level 2 2013 amp 2014 PDE data are not available in a form amenable to this analysis However links to 2013 data obtained via a
RTK request from the Senate Education Committee are provided at httpthenotebookorgblog158088pennsylvania-keystone-pssa-test-results-in-spreadsheet-format
3 PDE did not classify performance for Grade 3 in AY 2003 and 2004 For the purpose of this analysis the raw scores were ranked in these two instances Grade 11 PSSAs were discontinued in 2012-2013
