More information about the levels of cognition
  • Level 1 - Knowledge: This level requires candidates to recall specific information or facts. They should demonstrate the ability to remember and recognize details, terms, or concepts from their learning materials.
  • Level 2 - Comprehension: At this level, candidates are expected to show their understanding of the acquired information. They should be able to interpret, explain, and summarize. Candidates must go beyond mere memorization and demonstrate that they can grasp the meaning and implications of the information they have learned.
  • Level 3 - Application: The focus at this level is on candidates’ ability to apply their acquired knowledge in practical situations. They should be able to use what they have learned to solve problems, apply principles, or implement strategies in real-world scenarios.
  • Level 4 - Analysis: Analysis involves candidates breaking down complex concepts into smaller parts and comprehending the relationships between them. Candidates must display the ability to analyze information, identify components, and understand the underlying connections between them.
  • Level 5 - Synthesis: At this level, candidates are expected to exhibit the ability to create something new by combining different ideas, concepts, or elements. Candidates must demonstrate their capacity to generate hypotheses, design experiments, or develop original solutions to problems. Synthesis involves creativity and the integration of different elements to form a novel whole.
  • Level 6 - Evaluation: This level requires candidates to use judgments or assessments based on criteria and evidence. Candidates must critically analyze information, compare and contrast different perspectives, and make informed decisions. They should demonstrate the ability to evaluate the quality, validity, and reliability of information, arguments, or solutions.
