qualitative evaluation

qualitative evaluation

an evaluation method that yields narratives gathered primarily from unstructured methods of data collection, naturalistic observation, and existing records. As an initial or divergent phase of program evaluation, it seeks to allow maximum opportunity to frame evaluation objectives. This approach is usually associated with a goal-free evaluation rather than a goal-based evaluation. Compare quantitative evaluation.
