Tier 3 Expert Training and Teaching Roles
Before reading about Tier 3, a clinician should know which tier they are placing themselves in. This guide reads the published description of Tier 3 and the roles it names.
Your own procedure record
Write down your own record of procedures and experience. For a way to think about naming your skill level, Wikipedia has an entry on competence in human resources. A clinician in Summit, New Jersey who is scanning course listings can use that record to place each course.
How the tier is described
PubMed Central carries the description. It states: Tier 3 is expert-level training or an expert injector. This tier is for highly experienced practitioners seeking specializations.
The wording is about experience and specialization. It does not describe a beginner path.
What the training covers
The same source continues: This training covers advanced aesthetic procedures (combination treatments, ultrasound guided injections), ethical considerations, patient selection strategies, teaching, and mentorship roles in aesthetic medicines.
Three groups appear in that list. The first is advanced procedures. The second is decision topics, namely ethical considerations and patient selection strategies. The third is teaching and mentorship roles.

Teaching and mentorship
Plastic Surgery Practice published an article titled AAAMS Launches Mentorship Program to Support Early-Career Aesthetic Injectors. Read it as a practitioner-side view of mentorship, next to the tier description.
Placing your record in a tier
This step is done when you can say which tier your record fits and which of the three groups above you would want from a course. If your record does not fit Tier 3, treat this page as a map of what lies ahead rather than a next step.
