In 1997, with the adoption of the "Mathematics Content Standards for California Public Schools," California provided a foundation for a high-quality mathematics program that prepares all students for postsecondary education and a wide range of careers. This updated edition of the "Mathematics Framework for California Public Schools, Kindergarten Through Grade Twelve" is based on the standards and provides a context for continuing a coordinated effort to enable all students to achieve rigorous, high levels of mathematics proficiency.
