Why Keep a Portfolio? Below is an excerpt from an Edutopia post...

Designing a well-organized and professional teaching portfolio can give you an edge in a competitive job market, and help you score high marks on your school's teacher evaluation form. It is, however, a time-consuming endeavor (the average portfolio takes about two to three days of work), and once built, your portfolio will require regular attention. This post will help you decide whether or not a portfolio will serve your professional goals and how to go about designing a professional-looking site that showcases your teaching skills.

Do I Need a Portfolio?

There are several reasons to start building a portfolio:

• You want to share what you do and learn from others. Your teaching portfolio can be the home base of your personal learning network (PLN). You can repost articles you read, write blog entries about interesting aspects of your teaching experience, and mention professional development events that you have attended.
• Upload teaching artifacts and evidence of student learning. Many teacher evaluation instruments now rely heavily on learning artifacts (see Colorado SB 10-191). When showcasing student work, make sure to get proper permissions from the students' parents.
