CodeHS does not currently have a student-facing gradebook.
With CodeHS Pro, however, there is a teacher-facing gradebook that you can export into an Excel or .csv file!
Many schools export their CodeHS grades and then import them into the school’s Student Information System or Learning Management System.
To export your course grades, access your Gradebook and then select the file type you'd like to export them in.
More information on what's included with CodeHS Pro can be found here.
