The Combined Curriculum Document (CCD) is a resource created by the Kentucky Department of Education to show the connection between the Academic Expectations (what students should know and be able to do as a result of their school experience), the Program of Studies (the minimum required content standards students shall be taught to meet the high school graduation requirements), and the Core Content for Assessment Version 4.1 (the content that is appropriate to be included on the state assessment).

Core Content for Assessment version 4.1- represents the content that has been identified as essential for all students to know and will be included on the state assessment. This content is designed for use with, not instead of, Kentucky's Academic Expectations and Program of Studies to provide the focus for the development of the Kentucky Core Content Test (KCCT).
