Despite rising achievement levels in recent years, a substantial percentage of second- and third-graders do not meet state education standards in English-language arts and mathematics. Some groups of students are falling short by larger margins than others. English learners and students whose parents did not graduate from high school have the highest proportion who fall short of proficiency in second and third grade. Percentages of black, Hispanic, and economically disadvantaged students falling short of proficiency in the same grades are also high. Measures of student performance in kindergarten and first grade show similar patterns of who is ahead and who is behind.
