This Brief is intended to provide descriptive statistics about various aspects of algebra enrollment in the eighth grade. The first analyses describe who is taking algebra in the eighth grade; findings compare eighth-grade course enrollment percentages for students with different demographic, family, geographic, and school characteristics (table 1). The second set of findings looks at eighth-grade algebra enrollment levels in the schools and reports the percentage of students who attend schools with relatively low, medium, and high levels of eighth-grade algebra enrollment by demographic, family, geographic, and school characteristics (table 2). The next set of findings incorporates data collected at the end of fifth grade. Enrollment in algebra or higher is compared by varying levels of fifth-grade mathematics achievement (figure 1), and among students with relatively strong fifth-grade mathematics scores, enrollment is compared by sex and race/ethnicity (figure 2). Enrollment in algebra or higher in eighth grade is also compared for students with varying views about mathematics as self-reported in the fifth grade (figure 3). The final set of findings describe mathematics achievement scores and other student measures from the end of eighth grade for students not yet in algebra and those in algebra or higher. First, the eighth-grade mathematics scores for those in algebra by the eighth grade and those not yet in algebra are broken down by demographic, family, geographic, and school characteristics (table 3), and by fifth-grade mathematics score quintiles (figure 4). Findings are then presented that look at student-reported enjoyment of mathematics (figure 5) and future educational expectations (figure 6) by course enrollment. Standard Error Tables is appended. (Contains 6 tables, 6 figures and 18 footnotes.)
