From The Sacramento Bee: Class sizes in California are getting bigger. The California Board of Education granted 16 class-size waivers in an 11-month period ending in July. In addition, the board heard 16 more waiver requests at its meeting Aug. 2 and expects another 16 in September. The state had no requests for class size increases between 1999 and 2009. The state allows an average of 31 students in kindergarten, 30 in first through third grade and 29.9 in fourth through eighth grade.
