Assessment models are frameworks used to evaluate and measure the performance, skills, or knowledge of individuals or groups. These models provide structured approaches to gather data, analyze results, and make informed decisions. Common types include formative assessments, which occur during the learning process, and summative assessments, which evaluate learning at the end of an instructional period. Different assessment models can be applied in various fields, such as education, healthcare, and business. For example, in education, the Bloom's Taxonomy model helps educators design assessments that target different levels of cognitive skills. In healthcare, clinical assessment models are used to evaluate patient outcomes and treatment effectiveness.
