The participating school system's minority population, notably African Americans, ranked in the top five school systems in academic performance in reading and math when compared to other states and other African American populations across the United States. These measurements were taken from the National Assessment of Educational Progress (NAEP). The purpose of this investigation was to examine whether there was a significant achievement gap between races across system-wide assessments on a yearly basis. Results of the multivariate analyses of reading and mathematics scores indicated there were significant differences in both areas at the p less than 0.05 level on the TerraNova, Third Edition. These significant differences lend support to the results of the NAEP testing in 2007 and again in 2009 that demonstrated the gap. Discussion of the implications of this gap for the school system was presented. [The dissertation citations contained here are published with the permission of ProQuest LLC.
