Content Standards are constant across grade levels; however the scope of what is taught and assessed varies at grade levels.
Standards are general statements that identify what information students should know/understand or what skills/processes they should be able to do as a result of their educational experience.
Interval Benchmarks describe what students should know and be able to do at developmental levels to attain the standards.
To view specific Interval Benchmarks, use the yellow bar to the right.
