Infinite Campus's Learning Management System is called Instruction, and recently Campus has improved their teacher-interface to streamline navigation of instructional tools within a specific section. Starting Friday, November 17th, the Classroom navigation will be enabled by default, in the meantime, teachers can enable Classroom on their own to try out the experience.  

To enable Classroom, toggle the on/off switch in the top corner of the teaching center.  

Once Classroom is enabled, instructional tools previously found in the left panel are scoped to one of four tabs within Classroom.  The four tabs are: Classroom, Curriculum, Students, and Grades.  The list in the left panel becomes noticeably shorter.
