Utah’s achievement gap appears to be narrowing in some areas, but not in others, since No Child Left Behind took effect in 2002. A report issued Tuesday by the Center on Education Policy shows the gap between low-income and more well-off students narrowed in reading and math. Reading gaps between Hispanics and whites also narrowed in elementary, middle and high school grades examined. But when you look at Utah’s performance based on average test scores — called effect size — rather than the percent of students scoring as proficient, the gap between Hispanics and whites actually widened in reading across all grades analyzed.
