Exam outline and official sources
American Board of Opticianry (ABO), within American Board of Opticianry & National Contact Lens Examiners, Inc. (ABO-NCLE) · Currently published, undated NOCE Content Outline and Test Specifications, corroborated by the earlier February 2025 Basic Exam Handbook. No separate outline effective date is stated. The issuer's October 2026 fee-change notice states that examination content is unchanged. The workbook label 'Certified in Ophthalmic Dispensing (ABOC)' maps descriptively to ABO Basic Certification earned through NOCE; the issuer expands ABOC as American Board of Opticianry Certification.
This original 20-question sample covers selected topics across the outline. It does not reproduce official exam questions or cover every tested topic.
