Sierra Vista High School is a year-round, open enrollment high school offering both continuation and independent study programs to students within the Whittier Union High School District. Approximately 84 percent of Sierra Vista students are Hispanic/Latino, and 62 percent are identified as socioeconomically disadvantaged. The majority of the students are in grades 11-12, with many 5th year seniors working to finish their high school degrees. Sierra Vista was the first to begin piloting the Algebra 1—An Open Course in October 2010. The curriculum was ideal for the self-paced, blended course being designed as an alternative to traditional classroom instruction.
