This guide, which is intended primarily for upper-division undergraduate and graduate students in science, engineering, and mathematics, presents information about the potential applications of science and engineering education, courses and levels of education required for various science and engineering careers, and the career planning process. The following topics are discussed in the guide's six chapters: formulating career goals; determining how to meet career goals; identifying and developing the survival skills and personal attributes needed to succeed; determining the education required to meet specific career goals; finding the right job; and assuming responsibility for one's own career development. Also included are 13 case studies of how individuals who originally trained for a science or engineering career made the transition to a different career not directly related to their original field of study. Concluding the guide is a 64-item annotated bibliography. Two appendixes are included. The first examines possible scenarios for the various stages in the process of choosing, preparing for, finding, and/or changing careers. The second appendix is an article by Ellis B. Cowling titled "Skills and Attributes that Contribute to Success in Science or Engineering." (MN)
