Hi Alexia!

At the moment, there's no way to hide or edit the grade on the assignments. However, we are always working to add features that improve our site, and we love getting input from our community.

I've passed your feedback along to the team and it will be part of our conversation as we plan the future of Khan Academy.

Thanks for helping improve Khan Academy!

Hi alexia! Thank you for your suggestion here. 
One workaround we suggest is having assigning content items from courses with more general names (Re: Algebra 1 versus Get Ready for 8th grade) since there is some overlap between skills across different courses. 
I hope this helps and thanks again for your feedback! 

Just wanted to bump this topic. Khan Academy is an excellent resource for all students, but I'm reluctant to use the appropriate levels for my students when they are so far below grade level. Seeing "2nd grade reading" can be really demoralizing for special education students even though the content is great. 

Thank you!
