Hello @DaveHenry2
Thanks for posting this in the global Canvas Community!
This might be totally possible if Achieve offers an LTI integration that can be added/used to Canvas. I am not super familiar with Achieve and am unsure if an integration exists to allow Canvas and Achieve to talk with each other for grade and submission data.
Generally, your school/institutions Canvas admin would need to setup the integration on their side of things and this would then become an available app/Navigation link you can use in your Canvas course.
Is Achieve an app that Macmillan Learning developed? If so I was able to find THIS information an an integration that exists.
Hopefully this helps!
