You're looking at the contextual navigation for the page https://www.gov.uk/guidance/teachers-student-loan-reimbursement-guidance-for-teachers-and-schools
You can look at the contextual navigation for any page by replacing the part after /contextual-navigation in the URL (eg. /contextual-navigation/state-pension-calculator).
Note that this displays what the contextual navigation would look like if it were implemented. If the application hasn't been upgraded, it will show something else.
