博士学位的工作计划包括上述综合考试和资格考试。博士 数学专业的学生将在两年内在相同的两个领域（代数和实数分析）中参加资格考试。在读博士 应用程序课程中的学生将遵循一项并行政策，并在两个不同的领域进行了测试：统计领域学生的统计学和应用概率，以及应用数学领域学生的分析和微分方程。此外，还要求每个学生准备一份书面计划，以进行更多的高级课程工作和大量阅读研究文章。第三年也将需要高级主题考试。普通考试由候选人描述论文程序，博士论文及其辩护完成了博士学位的工作。未获得硕士学位的利哈伊学生必须获得72个学分，其中包括至
The plan of work for the PhD degree includes the Comprehensive Exam described above, and qualifying examinations. Ph.D. in Mathematics students will all take the qualifying examination in the same two areas, Algebra and Real Analysis, within two years. Students in the Ph.D. in the Applied Program will follow a parallel policy and tested on two different areas, Statistics and Applied Probability for students in the Statistics track and Analysis and Differential Equations for students in the Applied Mathematics track. In addition, each student will be required to prepare a written plan for additional advanced course work and substantial reading of research articles. An advanced topic examination will also be required in the third year. A general exam, in which the candidate describes the thesis program, and the doctoral dissertation and its defense complete the work for the PhD degree. A student entering Lehigh without a masters degree must take 72 credits including at least 48 regular course credits (i.e. not dissertation credits). These students typically earn as Masters degree during the process of their work. A student entering Lehigh with a masters degree must take 48 credits including at least 18 regular course credits (i.e. not dissertation credits).
