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.View Article
