Computer-adaptive testing (CAT) is an advanced assessment method that dynamically adjusts the difficulty of questions based on a test-taker's responses. By tailoring the difficulty level in real-time, CAT aims to provide accurate measurement of a person's abilities or knowledge with fewer questions, making assessments more efficient and personalized.
Key Features
- Dynamic adjustment of question difficulty according to candidate responses
- Shorter testing time compared to traditional fixed-form exams
- Use of Item Response Theory (IRT) for precise ability estimation
- Immediate scoring and feedback capabilities
- Enhanced test security through varied question sequences
Pros
- Provides a quick and efficient evaluation of abilities
- Reduces test fatigue by avoiding overly difficult or easy questions
- Offers highly personalized assessment experience
- Improves measurement accuracy with fewer items
- Increases test security through varied item exposure
Cons
- Requires a large bank of calibrated items for effective functioning
- Implementation can be costly and technically complex
- Potential for technical issues affecting test delivery
- May not be suitable for all types of assessments or populations
- Requires sophisticated algorithms and data analysis expertise
