The Association of Regulatory Boards of Optometry (ARBO) has provided resources to regulatory boards of optometry throughout North America since 1919. Boards of optometry serve as the licensing and regulatory arm of the optometric profession by formulating rules, or regulations, that govern and enforce the laws that grant the privilege to practice optometry, which is enacted by state legislatures. Thousands of optometrists have served their profession as members of these regulatory boards and many of these key opinion leaders have been leaders of ARBO. Throughout its history, ARBO has been the forum for all optometry licensing and regulatory agencies to meet, develop, and exchange ideas. Currently, ARBO's membership consists of 66 regulatory boards throughout the United States, Canada, Australia, and New Zealand. We provide programs to accredit optometric continuing education courses, to track and audit the CE attendance of licensed optometrists and to assist with license mobility. Our goal is also to be a conduit for sharing information among licensing boards to help them increase efficiency and decrease costs.
