COLUMBIA — South Carolina senators are discussing whether to block the implementation of nationwide education standards in math and reading.

A Senate panel is holding a second meeting Thursday on the so-called Common Core education standards. No vote was taken last week.

The state Board of Education adopted the curriculum in July 2010, following approval from the Education Oversight Committee. Forty-five states have adopted the standards on what kindergarten- through 12th-grade students learn in the classroom, replacing the standards that now vary from state to state.

But some say South Carolina should maintain control of classroom teaching. Greenville Sen. Mike Fair’s bill would block the implementation as scheduled in 2014.

South Carolina educators testified last week that teacher training on the standards has already started.
