RESUMO
The authors present snapshots of board certification in 1916, the year that the American Board of Ophthalmology was founded, 60 years later in 1976 as periodic recertification emerged, and speculation about what certification might look like in 2036. The concept of board certification and continuous certification in the medical specialties took shape at the beginning of the 20th century with the convergence of a new system of assessment, the emergence of certifying boards, and the creation of the American Board of Medical Specialties (ABMS). The importance of self-regulation is emphasized as are the principles underlying board certification and the standards that guide it to support its continued relevance as a valued credential and symbol of the highest standard in the practice of medicine.
