AI Marking Explained
Understand how IB Marker's AI provides accurate, IB-aligned feedback on your answers.
How AI Marking Works
When you submit an answer, our AI system follows a rigorous process to provide accurate feedback:
1
Question Analysis
The AI identifies the question type, command term (explain, evaluate, etc.), topic area, and maximum marks available.
2
Mark Scheme Reference
Your answer is compared against IB-aligned marking criteria specific to the subject and question type.
3
Content Evaluation
The AI assesses factual accuracy, use of terminology, depth of explanation, and relevance to the question.
4
Feedback Generation
Detailed feedback is generated highlighting strengths, areas for improvement, and a model answer for reference.
Accuracy & Reliability
Our AI marking system has been developed with accuracy as a top priority:
Trained on IB Content
The AI has been specifically trained on IB curriculum content, mark schemes, and examiner reports.
Multiple Model Verification
We use advanced AI models with cross-verification for consistent, reliable results.
Continuous Improvement
The system is regularly updated based on new IB guidelines and user feedback.
Conservative Scoring
When uncertain, the AI errs on the side of caution to provide realistic exam expectations.
Important Note
While our AI provides excellent practice feedback, final exam marks are determined by official IB examiners. Use AI feedback as a learning tool, not a guarantee of your final grade.
Understanding Your Feedback
Each marked answer includes several components designed to help you improve:
Your mark out of the maximum available. This reflects how well you met the marking criteria for that specific question.
Specific aspects of your answer that earned marks. This helps reinforce good habits and techniques.
Actionable suggestions for earning more marks. Focus on these areas in your future practice.

IB Mark Scheme Alignment
Our marking follows official IB assessment practices:
Command Term Recognition
The AI recognizes and applies appropriate criteria based on command terms:
Define / State
Requires a brief, precise definition or fact. Full marks for accurate, concise responses.
Explain / Describe
Requires detailed information showing understanding. Marks awarded for depth and clarity.
Analyse / Compare
Requires examining relationships and differences. Marks for identifying key features and making connections.
Evaluate / Discuss
Requires balanced arguments and conclusions. Marks for considering multiple perspectives.
Limitations & Best Practices
To get the most accurate feedback, be aware of these considerations:
Current Limitations
- Diagrams and graphs cannot be assessed - describe them in text where needed
- Mathematical working should be shown step-by-step in text format
- Very creative or unconventional answers may not receive full recognition
Best Practices for Accurate Feedback
-
Write Complete Answers
Don't use bullet points for essay questions. Write in full sentences as you would in an exam.
-
Use Proper Terminology
The AI recognizes and rewards correct use of subject-specific vocabulary.
-
Structure Your Responses
Clear paragraphs and logical flow help the AI assess your organizational skills.
