Test Structure
Science (215/217–220) 

Introduction

CSET: Science consists of two separate subtests, each composed of both multiple-choice and constructed-response questions. Each subtest is scored separately.

The structure of the examination is shown in the tables below. 

Table outlining the test format, number of questions, time, and passing score.
Test Name CSET: Science
Test Code
  • Subtest I (test code 215)
  • Subtest II (test codes 217–220)
    • Life Sciences (test code 217)
    • Chemistry (test code 218)
    • Earth and Space Sciences (test code 219)
    • Physics (test code 220)
Time
  • Subtest I: 4 hours
  • Subtest II: 2 hours
    or
  • Both subtests in a single session: 6 hours
Number of Questions
  • Subtest I: 100 multiple-choice questions and 4 constructed-response questions
  • Subtest II: 50 multiple-choice questions and 3 constructed-response questions
Proportions of subtest sections used to determine overall score
  • Subtest I: 80% multiple-choice questions and 20% constructed-response questions
  • Subtest II: 70% multiple-choice questions and 30% constructed-response questions
Format Computer-based test (CBT)

Test Structure

Subtest I covers general science content while Subtest II covers the candidate's area of concentration. A credential in this subject matter area authorizes teaching general and integrated science and the area of concentration. Science: Biological Sciences is the credential area for Life Sciences, and Science: Geosciences is the credential area for Earth and Space Sciences.
