CSET: Science

CSET: Science consists of 3 subtests:

  • Subtest I (test code 118)
  • Subtest II (test code 119)
  • Subtest III (test codes 120-123)
    • Biology/Life Science (test code 120)
    • Chemistry (test code 121)
    • Earth and Planetary Science (test code 122)
    • Physics (test code 123)

Subtests I and II cover general science content while Subtest III 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 Biology/Life Science, and Science: Geosciences is the credential area for Earth and Planetary Science.

You may register to take any one subtest or Subtests I, II, and III in a single test session.

Computer-based test (CBT) only:
  • Subtest I: 58 multiple-choice questions and 2 constructed-response questions

An on-screen scientific calculator is provided to examinees for the CSET Science subtests. Read more links to a PDF doc.

A periodic table is provided to examinees taking Subtest I (118), Subtest II (119), and Subtest III: Chemistry (121). A copy of the periodic table is available in the Sample Questions for each of these subtests.

A reference sheet containing constants, trigonometric functions, formulas, and notes is provided to examinees taking Subtest III: Physics (123). A copy of these reference materials is available in the Sample Questions for this subtest.

Subtests I, II, and III include one or more assignments that allow you to handwrite and scan responses. See scanning instructions links to a PDF doc and the hand-draw tutorial video link opens in a new window for information on how to use a response sheet for handwritten responses. (The instructions will be available during testing.)


Tests may include questions that are evaluated for future administrations and do not affect a candidate's score.
