Virtually all NSP courses are offered through patrols, with the exception of those offered through our affiliate organizations (link here to that page?).
Some patrols open their courses to non-members. You can search for those courses on the non-member course schedule (link here) using the course title, course number (obtained from the instructor) or patrol name.
Non-members who want to enroll in NSP courses need to create an account on the NSP website (link here).
