Learn about the Common Core State Standards Initiative. It provide a consistent, clear understanding of what your kids are expected to learn, so teachers and parents know what they need to do to help them. The standards are designed to be relevant to the real world, reflecting the knowledge and skills that our young people need for success in college and careers. They define the knowledge and skills students should master in their K-12 education to graduate high school and be able to succeed in college courses and in workforce training programs.
Particularly helpful is the myth vs. facts section. You can also discover if your state has adopted these standards.
