School districts may want to consider developing alternatives to traditional math-course sequences in order to better serve students and improve access to advanced math courses, according to a new report published by PACE.  Only half of all California high school seniors enroll in an advanced math class, despite evidence that enrolling in 12th grade math has a positive impact on college eligibility and success, according to the report. “Moreover, we note substantial inequalities in senior-year math enrollment and performance by race/ethnicity and socioeconomic status,” the authors write. “Given that a recent study of Los Angeles Unified School District high school graduates found that enrollment in a math course during 12th grade has a positive impact on college eligibility, enrollment, and persistence, this descriptive evidence raises deep concerns over uneven access to educational opportunities in math among California students.” The report highlights six partnerships between higher education and K-12 that developed advanced innovative math (AIM) courses as viable alternatives to traditional 12th-grade math courses.
