What they are checking: Empathy and patience with patients facing major life changes.
How do you keep your ABC certification current?
What they are checking: Commitment to continuing education required to keep the credential.

How would you teach a patient to put on and care for a new orthosis?
What they are checking: Clear patient teaching that improves wear and prevents injury.
About the work
You'd work under the indirect supervision of a certified orthotist or prosthetist. Where do you see the line between what you can do and what they must do?

What fabrication and repair work are you comfortable doing in the lab?
What they are checking: Hands-on fabrication skill, since the role includes fabricating, repairing and maintaining devices.
How do you document your work so the supervising orthotist or prosthetist can follow it?
