Key Facts: Chemistry License (STT) Exam
Saudi chemistry teacher licensure is administered by the National Center for Assessment (Qiyas) under ETEC.
The licensure pathway commonly includes a general pedagogical MCQ test (GTT) and a specialized chemistry subject test (STT).
The chemistry STT is distinct from the integrated general science STT and from separate biology or physics specialist exams.
OECD profiles describe ETEC teacher certification as separate subject-knowledge and pedagogical multiple-choice exams.
Qiyas professional tests are computer-based multiple-choice exams with roughly two hours of answering time commonly reported.
Saudi secondary science curriculum teaches chemistry as a separate subject with emphasis on practical skills and the scientific method.
Registration is handled through the Qiyas e-services portal at e-services.etec.gov.sa.

About the Chemistry License (STT) Exam
The Saudi Specialized Professional License Test in Chemistry is the ETEC/Qiyas subject-knowledge licensure examination for chemistry teachers seeking the professional teaching license. It measures deep chemistry content knowledge across stoichiometry, bonding, equilibrium, organic and analytical chemistry, thermochemistry and kinetics, laboratory safety, and chemistry pedagogy aligned to Saudi secondary chemistry standards—distinct from the integrated general science STT. This free practice bank offers 100 multiple-choice questions for STT preparation.
Exam sponsor: National Center for Assessment (Qiyas), under the Education and Training Evaluation Commission (ETEC). The requirements and fees below concern the certification or admission exam, separate from our free practice resources.
Assessment
Saudi professional licensure for chemistry 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 chemistry subject-knowledge MCQ test (STT). Tests are computer-based multiple-choice exams registered through Qiyas e-services. This specialization is distinct from the integrated general science STT and from separate biology or physics specialist licensure tests.
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 chemistry STT was not confirmed on the official pages reviewed for this bank. Verify the current standard in Qiyas e-services.
Exam / Certification Fees
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.
Exam sponsor websiteFees, eligibility, and exam policies can change. Confirm them with the exam sponsor before applying or paying.

Chemistry License (STT): Suggested Study Strategy
Frequently Asked Questions
Who needs the Saudi specialized chemistry professional license test?
The chemistry licensure pathway targets teachers of chemistry in Saudi public schools who must meet ETEC/Qiyas professional license requirements alongside Ministry eligibility rules. Teachers of integrated general science or other single sciences may sit different STT exams. Confirm your category in Qiyas e-services.
How is this different from the general science license test?
The chemistry STT emphasizes deep single-discipline content—stoichiometry, bonding, equilibrium, organic and analytical chemistry, and chemistry pedagogy. The general science STT tests integrated breadth across biology, chemistry, physics, and earth science at a shallower depth per discipline.
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 chemistry. This practice bank focuses on the chemistry specialization, not the separate general pedagogical component.
How many questions are on the live STT chemistry 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 chemistry 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.
