A Note from Curriculum & Instruction

The goal of curriculum and instruction is to provide information to improve student academic excellence by implementing criteria that targets content standards as well as communicating policy and expectations. We are also dedicated to providing instructional guidance.


 Academic Standards

Academic standards provide a common set of expectations for what students will know and be able to do at the end of a grade. College and career ready standards are rooted in the knowledge and skills students need to succeed in post-secondary study or careers.

While academic standards establish desired learning outcomes, curriculum provides instructional programming designed to help students reach these outcomes. Districts work locally to establish curricular programs that support student mastery of Tennessee’s academic standards, while reflecting unique community values.  Instructional practices should provide each student with the best opportunity to meet these standards by supporting individual learning needs.
