Malissa, basically what you’d want to do is name the course, assign a credit (for example, 1 credit for a full year course, 1/2 for a half-year course) and then describe exactly what the student did, and approximately how long it took to do it. You’d want to describe how you assess what the student did (when the work was “enough” for the credit) and you’d include any materials (books, videos, field trips, interviews, work experience, internships, whatever!) Here is an example that is also in a book I have:

Let me know if you have any more questions!
