About the Illinois Science Curriculum
How Illinois Learning Standards for Science Works
Illinois sets its own science standards through the Illinois Learning Standards for Science, which are organized around disciplinary core ideas, science practices, and crosscutting concepts.
How Illinois Differs
Illinois adopted NGSS-aligned standards and structures its sequence so that physical, life, and earth science strands are integrated across every grade rather than taught as separate courses.
How Illinois Science Progresses
Students build from Kindergarten observation and inquiry through 5th grade earth and physical science, then deepen concepts in 6th through 10th grade integrated courses.
How Illinois Assesses Science
The Illinois Science Assessment (ISA) tests students in 5th and 8th grade, measuring their grasp of the Illinois Learning Standards for Science across all three strands.
