Can a showcase portfolio be assessment portfolio as well?

Yes, a showcase portfolio can also serve as an assessment portfolio, as both types can demonstrate a person's skills and competencies. A showcase portfolio highlights an individual's best work, while an assessment portfolio typically includes a range of work to evaluate progress and proficiency. By carefully curating the showcased pieces to meet specific assessment criteria, one can effectively combine both purposes. However, it's essential to ensure that the portfolio aligns with the intended goals of assessment and displays a comprehensive view of abilities.
