This year the Center on Education Policy analyzed data on the achievement of different groups of students in two distinct ways. First, it looked at grade 4 test results to determine whether the performance of various groups improved at three achievement levels--basic and above, proficient and above, and advanced. Second, it looked at gaps between these groups at the proficient level across three grades (grade 4, grade 8 in most cases, and a high school grade). These two types of analyses show whether elementary school achievement has generally gone up for different groups of students and whether achievement gaps at different grade levels have narrowed, widened, or stayed the same. This paper profiles the student subgroup achievement and gap trends in Texas. Overall, student achievement trends in Texas went in an upward direction. On achievement gaps between groups of students, the overall tendency was toward narrowing of gaps; there was a mixed finding in reading using mean scores. (Contains 9 tables.)
