The Completion Rate of PhD in STEM: Understanding the Key Factors

In recent years, there has been a growing concern over the completion rate of PhD students in the fields of Science, Technology, Engineering, and Mathematics (STEM). According to a graphic from the ASCB (American Society for Cell Biology), approximately 37% of biology PhD students do not complete their degree. This percentage is likely to be similar across other STEM disciplines, suggesting a widespread issue.

Common Obstacles to PhD Completion

Finances often play a critical role in a student's decision to persist or leave their PhD program. A significant percentage of students cite financial insecurity as the leading cause for not completing their degrees at both the undergraduate and graduate levels. Specifically, financial strain is a major challenge that affects many PhD candidates, often leading to early termination of their studies.

Key Predictors of PhD Completion or Non-Completion

Multiplying factors influence the completion of a PhD in STEM. Some of the most common predictors include:

1. Marital Status

Getting married before the completion of a PhD can significantly impact a student's ability to focus on their studies. Balancing the demands of marriage with the rigorous academic workload can be challenging and may lead to an increased likelihood of non-completion.

2. Academic Performance in MSc

The grade attained during a Master's program can be a strong indicator of a student's potential to complete a PhD. Students who excel in their MSc often demonstrate a higher aptitude and persistence, which can translate into success in completing their PhD.

3. Financial Security

Financial insecurity not only affects a student's well-being but also their ability to commit fully to their academic pursuits. Funding, including scholarships, grants, and stipends, plays a crucial role in a student's decision to continue in a PhD program.

4. Subject Interest

A genuine interest in the subject matter is another critical factor. Students who are deeply passionate about their field are more likely to persevere through the challenges of a PhD. Conversely, those who are less engaged may struggle to stay motivated and complete their studies.

5. Supervisor’s Attitude

The relationship and attitude of the supervisor can significantly influence a student's experience and success in a PhD program. A supportive and understanding supervisor can provide the necessary mentorship and guidance, while an unsupportive environment can create an insurmountable barrier.

Conclusion

Understanding the various factors that contribute to the completion rate of PhD students in STEM is crucial for both current and prospective students. By recognizing and addressing these challenges, institutions can develop strategies to improve retention rates and overall success in PhD programs.
