This paper profiles the student subgroup achievement and gap trends in Mississippi for 2010. Mississippi made changes to its state testing program in the 2007-08 school year. Therefore, subgroup and achievement gap trends could not be calculated because fewer than three consecutive years of data were available, too short a period to constitute a trend. However, student subgroup achievement data for 2008 and 2009 is presented. (Contains 9 tables.)
