ST. PAUL, Minn. (WKBT/AP) -

Governor Mark Dayton signed a new anti-bullying law on Wednesday.

It updates what's been widely considered some of the weakest standards in the nation.

The signed Safe and Supportive Schools Act will force districts to track and investigate bullying cases. Staff will get extra training on how to deal with bullying and how to prevent it.

Those in favor of the bill say it will create a safe environment at schools. Opponents say it will do little to reduce bullying and will be expensive to put in place.

The new law does not require schools to notify parents when their child has been bullied. School administrators will decide whether to inform parents.
