Which term describes a collection of student work used to demonstrate growth over time?

• A. Informal Assessment
• B. Portfolio
• C. Interpretive Communication
• D. Task Completion

Answer: (B)

A portfolio is a curated collection of student work that demonstrates growth over time. In a language class, it gathers multiple artifacts—writing samples, speaking recordings, reading responses, and projects—over weeks or months, often with student reflections and teacher feedback. This setup shows how skills develop, how understanding deepens, and how goals are met, rather than judging progress from a single assignment. The portfolio supports both ongoing appraisal and final evaluation by providing evidence of progression toward proficiency and guiding future learning. The other ideas describe different notions: informal assessment is casual checks of understanding, not a sustained collection; interpretive communication refers to a mode of language use rather than a type of assessment; task completion centers on finishing a specific task rather than illustrating growth over time.
