Testing and evaluation are processes used to assess the quality, performance, and effectiveness of a product, service, or system. This involves conducting various tests to gather data, which helps identify strengths and weaknesses. The goal is to ensure that the item meets specific standards and requirements before it is released to users. In many fields, such as education, software development, and manufacturing, testing and evaluation play a crucial role. For example, in software development, rigorous testing helps detect bugs and improve user experience. Similarly, in education, evaluation methods assess student learning and program effectiveness, guiding improvements in teaching strategies.
