This implies a rather limited audience, at least during the initial stages of development. Artifacts chosen for inclusion should be meaningful first of all to the teacher, the primary audience, and second, to others who are involved. The final point to keep in mind is that portfolios are a form of dynamic assessment. In other words, what is put in at any given time may be added to or deleted as is fitting to the teachers' professional development. It has been generally observed that portfolios become increasingly unique as student teachers' progress through their teacher education program.
Artifacts are documents produced during the normal course work of a program.
For example, a paper written concerning child development, lesson plans, or reflective journal entries not written especially for your portfolio. Reproductions are documents about typical events in the work of the person developing the portfolio, but include events which usually are not captured. For example, a videotape of you teaching a lesson or planning with a colleague. Attestations are documents about your work prepared by someone else. For example, teacher associate or university consultant observations or letters from parents or students.
