5. Passing Portfolios on. The final decision item has to do with what is done with portfolios at the end of a semester or school year. They could, of course, be turned over to students. However, there are advantages to keeping portfolios over a long period of time and sharing them with other teachers. “Portfolios give you opportunities to promote continuity in your students’ educations and to collaborate with other teachers and your students in the process. By passing a portfolio on, you can share important information with the student’s next teacher” (p. 53). Dennie Palmer Wolf (1993) also feels that portfolios should be kept for long periods of time (several years), and that they should act as a type of “passport” as a student moves from one level of instruction to another.
