How do the most selective schools by university compare?

I'm looking into highly selective universities and want to compare them. What are some of the most selective universities globally, and what makes them stand out in terms of admissions?

It's possible to compare some of the most selective universities globally based on various factors, including admission rates, academic rigor, reputation, and special programs. Let me reel off some stand-out factors for some academically strenuous institutions:

1. Harvard University: Known for its long-standing history and prestige, Harvard boasts some of the world's best programs in numerous study areas. The acceptance rate is incredibly low (around 3%). Also, noteworthy is their generous need-blind financial aid policy available even for international students.

2. Stanford University: Stanford’s main calling cards include its top-rated engineering, computer science, and business programs. Its admissions process places a high emphasis on well-rounded profiles, demonstrated leadership, and involvement in extracurricular activities. Its location near Silicon Valley also provides opportunities for networking with tech giants.

3. Massachusetts Institute of Technology (MIT): MIT is globally known for its robust STEM-focused programs. It has a unique application process where it incites creativity and originality from its applicants, reflecting its value for problem-solving and innovation.

4. California Institute of Technology (Caltech): Like MIT, Caltech is internationally recognized for its robust STEM programs and boasts a close-knit academic community with an impressive faculty-to-student ratio. It values students with a strong curiosity for science and technology and a commitment to research.

5. University of Cambridge: It is considered one of the oldest and most prestigious universities in the world. With a structured and sometimes arduous admissions process, including subject-specific admissions exams and interviews, Cambridge seeks academically excellent students passionate about their chosen discipline. They are known for the 'collegiate system,' where students become part of smaller, specialized colleges that offer a more interpersonal and supportive context in the larger university setup.

6. University of Oxford: Similar to Cambridge, Oxford utilizes a rigorous admissions process with subject-specific tests and interviews. It offers world-renowned programs across a diversity of fields and follows a collegiate system providing a close-knit community for students.

Each of these universities' selective admissions process aims to ensure that their student body is composed of intellectual, committed, and passionate individuals. Given the level of competition at these schools, it would be wise to consider many other factors beyond selectivity while thinking about which college is right for you, such as location, size, academic programs, financial aid, student life, and more.
