California Science Test (CAST) Practice Exam 2026 – Your All-in-One Guide to Success!

The California Science Test (CAST) is an essential assessment tool designed to evaluate students' understanding of scientific concepts as well as their ability to apply scientific reasoning and practices. As an important component of the California Assessment of Student Performance and Progress (CAASPP), the CAST is conducted for students in grades 5, 8, and once in high school. To excel in this vital exam, comprehensive preparation is key. This is where our California Science Test (CAST) Practice Exam comes into the picture, offering you the best resources to master the test.

The CAST aims to measure students' skills in line with the California Next Generation Science Standards (NGSS), which emphasize analytical and conceptual thinking alongside knowledge recall.

Exam Format

The CAST is a computer-based assessment that presents a variety of question formats. This includes multiple-choice, constructed response, and interactive questions designed to simulate real-world science tasks.

• Question Variety: Expect a combination of question types. The CALAST includes multiple-choice questions, questions requiring written responses, and interactive questions.
• Science Focus: The test covers topics such as Physical Sciences, Life Sciences, Earth and Space Sciences, and Engineering, Technology, and Application of Science.
• Adaptive Testing: Questions adapt based on your answers, offering a personalized testing experience aimed at accurately assessing your capabilities.
• Time and Structure: Students are provided ample time to complete the test, which typically spans a few hours over one or multiple sessions, depending on the school district's schedule.

What to Expect on the Exam

The CAST isn't just about recalling facts; it's an examination of your ability to apply scientific practices and interpret data. It evaluates several scientific competencies:

• Analyzing and Interpreting Data: You'll be required to examine scientific data and draw informed conclusions.
• Scientific Practices: The test assesses your understanding of scientific practices such as asking questions, developing models, and designing and performing investigations.
• Crosscutting Concepts: You will need to demonstrate the ability to apply concepts that transcend disciplinary boundaries, such as patterns, cause and effect, systems and system models, energy and matter, structure and function, and stability and change.
