Which performance-based testing strategy involves students working on a project over an extended period?

The strategy that involves students working on a project over an extended period is indeed the exhibition. In educational settings, exhibitions are performance-based assessments that allow students to engage deeply with a topic or a project over a significant amount of time. This approach encourages them to apply their knowledge and skills in a creative and practical manner, often culminating in a presentation or display that showcases their work to peers, teachers, or even the wider community.

Exhibitions foster a thorough understanding of the subject matter, as students must conduct research, solve problems, and reflect on their learning process. The extended duration of these projects provides opportunities for critical thinking, collaboration, and the application of knowledge in real-world contexts, making them a valuable form of assessment in educational environments.
