• Problem-solving skills and creativity

• Research or project experience

• Essays that show intellectual passion

• Standardized tests (optional recently, but recommended)

Caltech reviews applications holistically but places significant weight on academic rigor and curiosity.

7. Tuition, Costs, and Financial Aid

Although tuition is high, Caltech offers robust financial support.

• Annual Cost (2024–2025): ~$85,000 (tuition, room, board, fees)

• Need-based aid only – no merit scholarships

• Need-blind admissions for U.S. students

• Generous grants often cover 100% of demonstrated financial need

• Around 60% of students receive financial aid

Caltech aims to ensure financial barriers don’t block talent.

8. Student Life and Culture

Life at Caltech is rigorous but tight-knit and collaborative. With under 1,000 undergraduates and about 1,300 graduate students, the community is small and deeply connected.
