Using data from the 2011 PhD Plus 10 Study of mid-career physics PhD recipients, researchers explored the supporting factors and barriers to success experienced by PhD physicists throughout their careers. The study examined the career experiences of respondents working in three different sectors (academia, government, and the private sector) and compared experiences between men and women. This report presents the data in two sections: (1) Career Success Factors and (2) Career Barriers. PhD physicists in mid-career have encountered a wide range of experiences that have helped or hindered their success during the past 10-15 years of their careers. Their experiences reveal that personal, social, organizational, and societal factors all play roles in professional careers, and the impact of these factors depends on whether one pursues a career in the private sector, academia, or government.
