Comments from Educators

I've been working with a student who is preparing to take a nursing exam. It it difficult to find a single website that combines all the subjects on the exam - CK-12 is one of the few and definitely the most comprehensive. The breadth of content on CK-12 is remarkable. The material is almost always of a very high quality. I'm happy to have discovered the site and will continue to incorporate its resources into my future teaching.

John P.

It is a great multimedia resource that students like to use collaboratively and independently.

John H.

It's a very fun and interactive way to teach and sum up the boring information teachers repeat again and again.

Joe M.

CK-12 IS AMAZING! It deepened my child's knowledge and understanding involving geology, health, and much more! Thanks a bunch for always being there for my child when he most needed it.

The CK flexbook has allowed our science department to have an up to date resource for most of our science classes. We have not had hardcopy text books for over 20 years.

Jim L.

It has been a great resource to use. I believe it benefits my students more than me, but it is certainly been a useful tool-resource.

Jim K.

I use it with special education students to find articles at lower reading levels. I also post links to articles on google classroom for students to read to reinforce their learning from class.
