What's New

Assessing, Preventing and Overcoming Reading difficulties online course is coming again this fall!

This is a self-paced, online course designed by David Kilpatrick PhD and follows his book by the same title. Through engagement in this series of 13 on-demand webinars, participants will understand the current research, implications, and the essential elements necessary for assessing, preventing, and overcoming reading difficulties. If you are not already part of the CDE SLD listserv, you may want to join because this is where the opening of that course will be announced sometime in August. The directions for joining the SLD listserv are at the bottom of this page. The other option is that there is an ongoing on demand version of this course that is accessible right now. It does not include the assessments or the discussion forum and the CDE credit hours are not available for this course, but it is a great companion piece to Dr. David Kilpatrick's book. You can join as a guest through the CDE LMS.
