Classification Standards Validation for High School Accountability

Explore classification standards and validation methods for high school accountability. Analyze data from nSPARC at Mississippi State University (SY 2011-12) and Mississippi Department of Education (SY 2012-13). Compare initial and validated standards on a scale of 0-1000 and 0-900. Examine composite score distribution, frequency distribution, and rating distribution for high schools. Investigate weighting indicators for graduation rate, U.S. History, and Science. Compare weighted and unweighted data using descriptives, correlation, and delta comparison analysis.
