The Kirkpatrick Four-Level Training Evaluation Model is an instructional design model that helps training designers objectively measure the effectiveness of their training.

The four levels of evaluation outlined in this model are: 

  1. Reaction: This measures the learners reaction or opinion of the training. 
  2. Learning:  This measures whether or not learners acquired the intended knowledge, skills, and attitudes. 
  3. Behavior: This measures whether or not learners apply what they learned on the job.
  4. Results:  This measures if the business goals were reached as a result of the training.
