The Muscogee County School District aligns all core curriculum and instruction with the Georgia Standards of Excellence. The Georgia Standards of Excellence provide clear expectations for instruction, assessment, and student work. They define the level of work that demonstrates achievement of the standards, enabling a teacher to know “how good is good enough.” The Standards of Excellence isolate and identify the skills needed to use the knowledge and skills to problem-solve, reason, communicate, and make connections with other information. They also tell the teacher how to assess the extent to which the student knows the material or can manipulate and apply the information. The performance standard incorporates the content standard, which simply tells the teacher what a student is expected to know (i.e., what concepts he or she is expected to master). Additionally, it adds to these concepts by providing three additional items: suggested tasks, sample student work, and teacher commentary on that work.
