Hi Jennie68,
Education.com is created by a team of professionals from a variety of backgrounds. You can learn more about the organization (including its management, expert panelists, and partners) in this section of the site:
http://www.education.com/about/us/
Some of the content on the site is provided by nonprofit and government organizations, and their websites are hyperlinked from their profiles on the site (which you can click to from the articles they contributed).
Some of the content (such as JustAsk Q&A, comments on articles, and school reviews in SchoolFinder) is created by the website's community of users (including members and visitors like you).
Thanks for asking this question!
