Sometimes teachers cannot access the assessment site. There might be several reasons for this.
First, check with your school/district's site administrator. This is the person who issued your eBook to you and they might have identified you as a student in the system. Students do not have access to the assessment site. If you also have a student version of the eBook, you might be trying to log into that account. So, log out and log in again using your teacher email and information.
Log into your eBook and look for the CPM Assessment button at the lower right of the screen. This is how to access the assessment site; do not try to go to the site directly. The site needs the verification that you are logged in, and that you are a teacher.
