Recent reforms in educational standards—including the Common Core math standards and the Next Generation Science Standards—have altered the expectations placed on California’s teachers. Other changes, such as requiring college prep courses for high school graduation, will further increase the demand for math and science teachers. The state’s teacher workforce has already changed significantly in the past 15 years, but it will need to further evolve to meet the demands of the future.
These are a few of the challenges ahead:
- Although the number of math and science teachers has increased in the state, there are fewer of them than in other core subjects. As a result, the average class size in math and science at all levels is larger in California than in other states. For instance, the average class size for high school science in California is 27, well above the national average (22). Similarly, average enrollment in high school math is 25, which is again higher than the national average (21).
- The teacher workforce in math and science is aging rapidly. In 2016, the median age of the state’s math and science teachers was 44, three years older than the national average. In the next five years, California will need to replace at least 11% of these teachers due to retirement. About 12% of districts will need to replace at least 20% of their teachers.
- The composition of the teacher workforce in math and science has changed in recent years, yet it still does not reflect the diversity of California students. In the 2000–01 school year, only 10% of math and science teachers were Latino; today, 17% of them are (while 54% of the student body is Latino). The share of Asian teachers has increased slightly, while the share of African American teachers remains unchanged. Research shows that teachers of color play a critical role in helping students of color succeed.
As California’s schools continue to implement new math and science standards, the challenge of developing a larger and more diverse teacher workforce will loom large. There are examples of efforts both in California and in other states designed to address some of these challenges. For example, Call Me MISTER in South Carolina aims to recruit college students to increase the incoming teacher pool, while other programs—like Boston Public Schools’ High School to Teacher Program—reach out to students in high schools. In addition, some programs focus on recruiting members of the local community (e.g., Teach Tomorrow in Oakland, the San Francisco Teacher Residency program, and the Grow Your Own programs in Illinois).
These initiatives represent potential models, but they would need to scale up quickly to address the challenges ahead. PPIC’s ongoing research into the implementation of the Next Generation Science Standards suggests that the high demand for quality science teachers is an emerging implementation concern.




The fact that most 11th-grade students are not yet ready for college is not necessarily news for California. Since 2004, California students have been able to participate in California’s Early Assessment Program (EAP), which used an optional statewide test to determine college readiness levels of 11th-grade students. The college readiness identification component of the new tests is based on the EAP and informs 11th grade students whether they are ready, conditionally ready, or not ready for college.
But there is also some good news here for California. For students, new ratings regarding college readiness come early enough for the information to help before they enroll in their 12th-grade classes.
To the right we present results for the CST and the Smarter Balanced tests, alongside California students’ scores on the National Assessment of Educational Progress (NAEP), a national ongoing assessment of what children know in a variety of subject areas. While these three test results are not directly comparable because each measures competence relative to different standards and each has its own definition of what it takes for a student to score “proficient,” it is important to have a clear sense of how our students are faring on each. The Smarter Balanced test results for each student group are higher than the NAEP, but low relative to the most recent CST.
California’s public school system has seen dramatic changes in recent years, and the 2014–15 Smarter Balanced test results are an important baseline to measure how these changes are affecting students. In the past, California students’ test results improved almost every year that the CST was administered. Today, both the Common Core State Standards and the LCFF aim to improve outcomes for all students and close achievement gaps. Multiple years of Smarter Balanced test results will be needed to monitor progress. These new higher standards are meant to improve outcomes well beyond secondary schooling, and the least advantaged students have the farthest to go. The new curriculum and new funding should help get them there.
