American Board of Opticianry & National Contact Lens Examiners, Inc. (ABO-NCLE) · Official live CLRE basic Content Outline and Test Specifications, opened on 2026-10-12; the page states no publication or effective date. Its eight domain weights are the basis for these materials. The issuer's handbook directory links to a July 2026 Basic Exam Handbook, but that file's contents were not readable through the browser. The February 2025 handbook was opened as historical corroboration, not substituted for the July 2026 edition. The workbook examination name matches the official CLRE name; the assigned slug is preserved.

This original 20-question sample covers selected topics across the outline. It does not reproduce official exam questions or cover every tested topic.
