Assessment and evaluation are processes used to measure and understand the performance, skills, or knowledge of individuals or groups. Assessment typically refers to the ongoing process of gathering information to inform teaching and learning, while evaluation is the systematic determination of a subject's merit, worth, or significance based on criteria and standards. Both assessment and evaluation can take various forms, including tests, quizzes, observations, and surveys. They help educators, employers, and organizations make informed decisions about instruction, training, and resource allocation, ultimately aiming to improve outcomes and effectiveness in various settings.
