An ePortfolio is a wonderful tool for making sense of your work and to showcase it. But there are important issues to consider when posting your work online. You can set site visibility settings on your ePortfolio and be judicious about sharing - especially while you are in the process of building the ePortfolio.
Please do NOT post your course evaluations to your ePortfolio. These are part of your official transcript and are protected by FERPA (Federal Educational Records Protection Act). You can certainly reflect on the evaluations you have received.
If your committee wants to see evaluations and self evaluations in one place, you can either print them out, put them into a document you can send electronically, or make a "hidden" page. That is, your can put evals and self-evals into a Google Doc that is only shared with your committee - a link to such a page would only work for them.
Once your ePortfolio is complete, you can consider adding a Creative Commons license to your site to protect your creative and intellectual content, which signals to readers that they cannot reproduce your work or cite it without attributing it to you.
