Key Facts: Biology License (STT) Exam
Saudi biology 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 biology subject test (STT).
Separate specialist STT exams exist for biology, chemistry, physics, and integrated general science teachers in Saudi Arabia.
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.
Prep sources for biology licensure sometimes describe tiered pass thresholds at about 50, 70, and 80 out of 100 for different license levels.
Registration is handled through the Qiyas e-services portal at e-services.etec.gov.sa.

About the Biology License (STT) Exam
The Saudi Specialized Professional License Test in Biology is the ETEC/Qiyas subject-knowledge licensure examination for biology teachers seeking the professional teaching license. It measures specialized content knowledge across cell biology, genetics, ecology, physiology, evolution, microbiology, laboratory safety, and biology pedagogy aligned to Saudi secondary biology standards—distinct from the integrated general science STT and from separate chemistry or physics specialist licensure tests. 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 biology 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 biology 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 chemistry or physics specialist exams.
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, with tiered license levels sometimes described at about 50, 70, and 80 out of 100. A single fixed public pass mark for the biology 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.

Biology License (STT): Suggested Study Strategy
Frequently Asked Questions
Who needs the Saudi specialized biology professional license test?
The specialized biology licensure pathway targets teachers of biology in Saudi public schools who must meet ETEC/Qiyas professional license requirements alongside Ministry eligibility rules. Teachers of integrated general science may sit the separate science STT instead. Confirm your category in Qiyas e-services.
How is this different from the general science license test?
This biology STT emphasizes deep single-discipline content in cell biology, genetics, ecology, physiology, evolution, microbiology, and biology pedagogy. The general science STT tests integrated breadth across life, physical, and earth sciences 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 biology. This practice bank focuses on the biology specialization, not the separate general pedagogical component.
How many questions are on the live STT biology 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 biology-focused 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, with tiered license levels sometimes described at about 50, 70, and 80 out of 100. 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.
