Disadvantages of Portfolio
• Portfolio is a very time-consuming assessment method in terms of planning, responding, correcting and providing feedback.

• Plagiarism can occur.
• It is a subjective assessment method and teachers sometimes find it difficult to assess, as it is difficult to measure reliability.
