As they gain experience, geologists are given more difficult assignments and may be promoted to supervisory positions, such as project leader or program manager. A geologist with a bachelor's degree has little chance of advancing to these higher level positions. Continued formal training and work experience are necessary, especially as competition for these positions grows more intense. A doctorate is essential for most college or university teaching positions and is preferred for much research work.
