Final answer:
The institutional portfolio is the one passed from teacher to teacher, containing assessments and student work relevant to instructional outcomes.
Step-by-step explanation:
The institutional portfolio is typically the one that is passed from teacher to teacher at the end of the year. It includes collections of student work and assessments that provide a profile of instructional outcomes, which can be useful to the next teacher.
An individual portfolio is a personal collection of a student's academic work and accomplishments. A teacher portfolio typically includes a teacher's lesson plans, assessments, and professional development experiences. Lastly, a showcase portfolio is designed to present the best work of a student or a collection of best practices by a teacher.
In contrast to individual or showcase portfolios that might be unique to a student or a teacher, the institutional portfolio is shared across faculty to assess the educational progress institution-wide and is closely tied to curriculum and student performance at a more systemic level.
