How do you sign PhD in education in a signature?

To sign "PhD in Education" in a signature, you would typically write "PhD" followed by a comma and then "EdD" if you hold a Doctor of Education degree, or simply "in Education" if you want to specify the field. For a more formal signature, you could also include your full name first, followed by your title. For example: "John Doe, PhD in Education." Keep it clear and professional to convey your academic credentials effectively.
