Although Hispanic students have continued to close the “equity and excellence gap” in 15 states in the Advanced Placement courses, gaps persist in California and Texas, two of the biggest states with a high percentage of Hispanics in their population, the College Board reveals in its annual AP Report to the Nation.

While more minority students are entering AP classrooms, significant gaps remain, the College Board reports. In California, for instance, where Hispanics make up 37 percent of the student  population,  30.7 percent of the Hispanic students  scored three or higher in the tests. In Texas, the margin was lower with 32.6 percent of Hispanic students scoring three or higher. In that state, Hispanics are 36.5 percent of the student population in public schools.

“More students from varied backgrounds are accomplishing their AP goals, but we can’t afford to believe equity has been achieved until demographics of successful AP participation and performance are identical to the demographics of the overall student population,” says College Board President Gaston Caperton.

There was little discrepancy between AP exam enrollment rates and overall enrollment rates for Hispanic and White students, while Asian American students represented a disproportionately higher number of AP exam enrollees.

While several states, including Florida, Georgia, Maryland and Oklahoma, have been able to close the equity gap for Hispanic students, no state with large numbers of African-American or American Indian students has yet to close the gap, the report says.

Massachusetts saw a 41 percent increase in students taking the AP tests, with more than 900 Hispanic students who took at least one AP exam in high school, which is more than double the number five years ago.

State-based initiatives are key in closing the success gap between underrepresented students and their White counterparts, the report highlights. Florida’s Partnership for Minority and Underrepresented Student Achievement program has produced outstanding results. Hispanic students comprise 21.8 percent of the population in Florida, of which 27.6 percent have scored 3 or higher in the tests.
