SPRINGFIELD (CBS) — A proposal pending in Springfield would set new requirements in sex education classes.

The Senate narrowly passed a bill that would mandate that sex education classes from sixth grade through high school include instruction about contraception and abstinence.

Republicans objected to the bill, saying that it should be up to each town’s school board to decide what should be taught in their schools

Supporters of the bill say instruction about contraception is needed because so many teens are having sex.

The bill would allow parents to exempt their children from the classes. The bill now goes to the House.
