Explanation: Bacteria are prokaryotes without a membrane-bound nucleus.

About the Science License (STT) Exam

The Saudi Specialized Professional License Test in Science is the ETEC/Qiyas subject-knowledge licensure examination for general science teachers seeking the professional teaching license. It measures integrated content knowledge across biology, chemistry, physics, earth and space science, scientific inquiry, laboratory safety, environmental science, and science pedagogy aligned to Saudi middle and secondary science standards—distinct from separate biology, chemistry, and physics specialist licensure tests. This free practice bank offers 100 multiple-choice questions for STT preparation.

Assessment

Saudi professional licensure for general science teachers is administered by Qiyas under ETEC. Candidates generally must meet Ministry eligibility requirements and pass a general pedagogical MCQ test (GTT) plus a specialized integrated science subject-knowledge MCQ test (STT). Tests are computer-based multiple-choice exams registered through Qiyas e-services. Separate specialist STT exams exist for biology, chemistry, and physics teachers.

Time Limit

Commonly about two hours of answering time for Qiyas professional tests, plus early arrival for identity verification; confirm the duration shown for your registered session.

Passing Score

Older licensing documentation cited 50% on subject and pedagogical components; current prep sources often cite about 60% per component. A single fixed public pass mark for the science STT was not confirmed on the official pages reviewed for this bank. Verify the current standard in Qiyas e-services.

Exam Fee

Commonly reported at about 100 SAR per licensure test component, with higher fees sometimes cited for repeat attempts. Confirm the current fee in the Qiyas e-services portal before payment. (National Center for Assessment (Qiyas), under the Education and Training Evaluation Commission (ETEC))

Science License (STT) Study Tips from Top Performers

1Review the Saudi national science curriculum domains—biology, chemistry, physics, and earth science—for Grades 4–12 in the TIMSS encyclopedia, then practise integrated MCQs under timed conditions.
2Do not neglect the separate general pedagogical licensure component (GTT) if your eligibility requires both tests; this bank practises only the integrated science STT specialization.
3Rebuild weak areas systematically: if you miss ecology or electricity items, revisit those units before moving to genetics or optics questions.
4Practise under timed conditions with roughly 1–2 minutes per item to match the pacing of Qiyas professional computerized tests.
5Connect content review to pedagogy and lab-safety items—know common student misconceptions (e.g., seasons caused by distance from the Sun) and effective inquiry-based responses.

Frequently Asked Questions

Who needs the Saudi specialized science professional license test?

The integrated science licensure pathway targets teachers of general or integrated science in Saudi public schools who must meet ETEC/Qiyas professional license requirements alongside Ministry eligibility rules. Teachers specializing only in biology, chemistry, or physics may sit separate specialist STT exams instead. Confirm your category in Qiyas e-services.

How is this different from the biology, chemistry, or physics license tests?

This general science STT emphasizes integrated breadth across life, physical, and earth sciences at middle and secondary teacher level. Separate specialist STT exams exist for deep single-discipline content in biology, chemistry, and physics.

Is there only one test for the professional license?

No. Saudi teacher licensure commonly requires a general pedagogical multiple-choice test (GTT) plus a specialized subject-knowledge test (STT) in science. This practice bank focuses on the integrated science specialization, not the separate general pedagogical component.

How many questions are on the live STT science exam?

Public prep materials for specialized teacher tests often describe roughly 60–88 items in a timed computerized session. ETEC does not always publish one fixed count on the main pages reviewed for this bank. This free practice set has 100 integrated-science MCQs.

What is the passing score and exam fee?

Older documentation cited 50% on subject and pedagogical components; current prep sources often cite about 60% per component and about 100 SAR per test. These figures were not confirmed as a single stable public table on the official Qiyas pages reviewed for this bank. Always verify current rules in Qiyas e-services before registering.
