Built for the people taking this exam.
Experienced CSTs, military-trained first assistants, and other licensed surgical professionals pursuing the formal first-assistant credential to expand their scope and earnings.
Why it matters in 2026
The career signal.
Surgical first assistants who hold the CSFA command meaningfully higher pay than non-credentialed assistants and unlock first-assist roles in hospitals and ambulatory surgical centers that require formal certification for credentialing and insurance reimbursement. The CSFA is the most recognized non-PA/non-RNFA first-assistant credential.
