Inequities of Enrollment in Gifted Education: A Statewide Application of the 20% Equity Allowance Formula
Underrepresentation in gifted education for ethnically diverse student groups has been widely recognized. Two recent federal district court decisions defined the lower limits of equitable participation using the 20% equity allowance formula proposed by Donna Ford. The purpose of this article was to evaluate the application of the 20% rule to identify the prevalence of inequity and associated variables in Texas gifted education programs. Using data from the Office of Civil Rights and Texas Education Agency, the authors applied the 20% rule to demographics of K-12 gifted education programs in Texas to identify inequity and used Bayesian regression with district characteristics to investigate contributing factors of inequity. Only 282 of 994 (28.4%) districts met equity standards for Hispanic students. Second, Bayesian regressions with district-level characteristics of students, teachers, and expenditures were used to identify factors associated with inequitable enrollment of Hispanic students. Overall, the model accounted for 12.9% variance (R2 = 0.129, 95% highest density interval [0.095, 0.170]), with increasing variance explained by district subsets (i.e., city, suburb, town, rural). Furthermore, the results of the regression models revealed the percentage of Hispanic and White teachers were inversely associated with inequity across all district subsets. It is postulated that the mechanism of inequity is in the teacher referral process, frequently used as a determinant of gifted education enrollment. The authors suggest means of addressing this reality.
