Technical Issues

I’ve never taken an online course. What are the technical requirements?

We can only guarantee that our courses are compatible with Windows Internet Explorer 7.0 and 8.0 or Mac Safari 4.0 and 5.0. An Internet connection that is 56K or faster is recommended. The screen resolution is best viewed at 1024 x 768; however, 800 x 600 will also work.

Important: Please disable your pop-up blocker for this site. The course utilizes pop-ups to pose questions to participants, also to provide links to resources and articles.

Do I have to install any additional software?

No. Many computers already have Adobe Acrobat Reader and Adobe Flash Player installed. If your computer is several years old, you may need to download these software programs.

  • Adobe Acrobat Reader: This software if required to read selected PDF articles and resources included in the courses. To download, click here.
  • Adobe Flash Player: This multimedia viewer is required to watch video commentary clips included in the courses. To download, click here.

Do I need a printer?

Yes, you will need access to a printer to print your certificate(s) of completion.

What if I don’t have access to a printer to print my certificate?

CADER online courses are available via the Internet, and you can print your certificate from any computer with an Internet connection. You do not have to print the certificate from the same computer on which you completed the online course.

If you cannot access a computer with a printer, we are happy to send you a copy of your certificate. To order a printed certificate, please contact CADER by e-mail at or by phone at (617) 358-2626.

Do I need audio speakers?

Most CADER online courses contain audio clips and you will need speakers to listen to these clips. However, all audio clips have been transcribed and you can complete an online course without speakers.

Do I have to take an online course in one sitting?

CADER online courses do not have to be completed in one sitting. To be redirected to the last section you completed, CADER recommends you save your last page as a internet favorite page and then logout. Click on the internet favorite page when you are ready to login and you will be redirected to your last page.
