The Occupational Physicians Scholarship Fund (OPSF) was established 20 years ago with the goal of helping to address the critical shortage of qualified physicians entering occupational and environmental medicine (OEM). We examined descriptive and outcome measures to evaluate its success. Information was obtained from members of the original board of directors, the OPSF office, and the American Board of Preventive Medicine (ABPM). Most of the scholars (88%) are diplomates of the ABPM, certified in OEM. Scholars represent 6% of board-certified OEM physicians, score higher on the certifying examination than other examinees, practice in all regions of the United States, and are represented in diverse practice settings. The OPSF has achieved its objectives, producing well-trained physicians who contribute to the growth and vitality of the specialty improving worker health, business productivity, and the environment.
