Sacramento County's teaching force is more qualified than most of the state to meet a controversial requirement that all eighth-graders be tested in algebra.
Eighty-two percent of Sacramento County's middle school algebra teachers are fully credentialed with a math authorization, according to a study released Wednesday.
That compares with 66 percent statewide, meaning one-third of California middle school algebra teachers are under-prepared or are teaching outside their field.
The numbers, included in a report by the Center for the Future of Teaching and Learning, are for the 2007-08 school year.
And this is after 7 years of the No Child Left Behind Act, which requires certified teachers in every classroom.
