Strengthening Families Starts Feb. 27


Common Core Standards

The Common Core Standards are the new standards that students will encounter in K-12 schools. They provide a consistent and clear understanding of what students are expected to learn, so teachers and parents know what they need to do to help them.

For more information about the Common Core Standards and what our district is doing to prepare, please visit our district's website.
