The process of gathering information in order to make good decisions.  It is broader than testing and includes both subjective (opinion) input and objective (fact) input.  Evaluation can take many forms including memorization tests, portfolio assessments, and self-reflection.  There are at least six major reasons for evaluating training, each requiring a different type of evaluation:

• Improve the instruction (formative evaluation)
•  Promote individual growth and self-evaluation (evaluation by both trainer and learner)
• Assess the degree of demonstrated achievement (summative evaluation attained by the trainer.
• Diagnose future learning needs (of both trainer and learner)
• Enhance one’s sense of merit or wotth (learner)
• Identify or clarify desired behaviors (trainer).
