Exam Overview
The GACE Biology Exam (2025–2026) is a subject assessment used to evaluate your readiness to teach biology in secondary schools.
It measures both content knowledge and application skills required in a classroom setting.
Administering Body
- Georgia Professional Standards Commission (GaPSC)
- Testing services are delivered through authorized testing providers
This exam is part of the teacher certification process in Georgia (USA).
Exam Pattern
The exam is typically divided into two subtests.
| Component | Description |
|---|---|
| Test I | Foundational biology concepts (cell biology, genetics, evolution) |
| Test II | Applied biology (ecology, organismal biology, scientific inquiry) |
You can take:
- Each subtest separately
- Or both together in one session
Number of Questions
- Approximately 100–160 selected-response questions
- Mostly multiple-choice questions (MCQs)
Some questions may include:
- Data interpretation
- Graphs and tables
- Experimental scenarios
Time Duration
| Test Option | Time Allotted |
|---|---|
| Single subtest | About 2–2.5 hours |
| Combined test | About 4–5 hours total |
Time management is critical due to scenario-based questions.
Scoring System

Score Interpretation
| Score Range | Meaning |
|---|---|
| 220 and above | Passing |
| Below 220 | Retake required |
Your score reflects your ability to:
- Understand concepts
- Apply knowledge
- Analyze biological data
Content Areas Covered
The exam focuses on five major domains:
- Cell Biology
- Genetics and Evolution
- Scientific Inquiry and Technology
- Organismal Biology
- Ecology
Questions often combine multiple topics in one scenario.
Importance of the Exam
This exam is a mandatory requirement if you want to teach biology in Georgia public schools.
Why It Matters
- Confirms your subject knowledge competency
- Validates your readiness to teach biology concepts

What the Exam Actually Tests
The exam does not focus only on memorization.
You will be tested on:
- Application of biological concepts
- Interpretation of data, charts, and experiments
- Understanding of real classroom scenarios
What to Focus on During Preparation
- Core biological processes (not isolated facts)
- Concept connections across topics
- Practice with data-based questions
Ask yourself:
Can you apply this concept to a real situation?
Can you interpret experimental results?
Can you eliminate incorrect answer choices logically?
Quick Exam Snapshot
- Computer-based test
- 2 subtests
- 100–160 questions
