Parents will probably have to wait a little longer before putting their kids into kindergarten.

On Thursday, lawmakers gave final-round approval to a bill that would push forward by 75 days the age-cutoff date at which children could enter kindergarten. Governor Dave Heineman must sign the bill for it to become law.

The bill would require that children be 5 years old by July 31 to be admitted. The current date cutoff is 5 by Oct. 15.

Supporters say thousands of parents and teachers have complained that kindergarten classes now often have children at too many ages and stages of development, making it hard to teach them.

Children still could be allowed to enter earlier if assessments show they are ready for kindergarten.
