Funding:
- A loss of funding at the institutional, school, or department level can reduce the number of applicants they can support and accept.
- Less funds for and assistantships can mean accepting fewer students
- Many students are admitted to work with particular faculty and are supported by faculty members' grants. A change in grant funding means that some qualified students won't be admitted.
- Whether faculty are available and able to take on students influences the number of students who are accepted in any given year.
- Faculty are sometimes away on sabbaticals or leaves. Any students who would be accepted to work with them are often out of luck.
- Sometimes faculty are overloaded and do not have space in their lab for another student. Good applicants are turned away.
- Some graduate programs require that students have access to laboratory space and specialized equipment. These resources can accommodate only so many students.
- Other programs include internships and other applied experiences. If there aren't enough slots, then well-prepared students do not get admitted to the graduate program.
