A portfolio is a collection of work prepared, maintained and developed by a learner. Portfolios can contain information about the learner and about their learning experiences, and examples of their work.

Example
The Council of Europe uses Language Portfolios as part of its framework for the learning of European languages.

In the classroom
Aside from direct benefits for the learner, portfolios are a very useful tool for enabling parents to take an active role in their children's learning. They can read their child's portfolio and add their own comments and contributions.
