This Collection contains three seminal modules by Authors Ana Rojas-LeBouef and John R. Slate, professors and researchers from Sam Houston State University in Texas. They are nationally recognized scholars in the area of the academic inequity between White and Non-White students. This paper is divided into three chapters. Chapter 1--The Achievement Gap between White and Non-White Students: A Conceptual Analysis--discusses the results of numerous studies in which the achievement gap and related variables were analyzed, and also demonstrates the continued presence of an achievement gap among Whites, non-Whites, and students with a label of Limited English Proficient (LEP). Chapter 2--Reading and Math Differences Between Hispanic and White Students in Texas: A 16-Year Analysis--examines differences in academic achievement among students who were White or Hispanic using archival data from the Texas Education Agency's (TEA) Academic Excellence Indicator System (AEIS). Data examined were fifth grade reading and math passing rates from the 1993 through the 2009 school years. Chapter 3--Reading and Math Differences Between Hispanic Students and Students Who Are Limited English Proficient: A Lack of Equity--examines differences in academic achievement among students who are Hispanic or designated as being Limited English Proficient (LEP), using archival data from the Texas Education Agency's (TEA) Academic Excellence Indicator System (AEIS). Data examined were fifth grade reading and math test scores from the most recent 7 years of statewide data. (Contains 36 footnotes, 4 figures, and 16 tables.)
