Key Points

A portfolio is a compilation of a student's work, achievements, and progress over a certain period.

• It can include a variety of materials such as assignments, projects, essays, artwork, and reflections.
• Portfolios are often used as a tool for assessing and showcasing a student's growth and accomplishments across different areas rather than simply focusing on marks or grades.

 Additional InformationHere's why the other options are not as accurate:

• Collection of student's marks over a period of time: This only represents one aspect of student performance and can be misleading if not accompanied by other evidence of learning.
• Collection of student's grade over a period of time: Similar to marks, grades offer a limited view of student learning and do not provide insights into the learning process or individual strengths and weaknesses.

Therefore, a portfolio should be primarily viewed as a collection of student work that demonstrates their learning over time, not just a record of marks or grades.
