Science

California's Science Test (CAST) Interim Assessment (IA) for students in grades three, four, five, middle school, and high school have three assessments that cover all three science domains.

• Physical Science
• Earth and Space
• Life Science

Each CAST AI consists of two segments:

• One discrete segment
• One performance task segment

Within the Next Generation Science Standards (NGSS), there are three distinct and equally important dimensions to learning science. These dimensions are combined to form each standard, or performance expectation, and each dimension works with the other two to help students build a cohesive understanding of science over time.

• Crosscutting Concepts
• Science and Engineering Practices
• Disciplinary Core Ideas
