Caltech also offers a 60–90 minute self-guided walking tour and a 360-degree virtual tour through admissions.caltech.edu.

Caltech Admission Requirements — CBSE / State Boards and Cambridge A Level

The table below summarises what Caltech looks for from students applying through each pathway. Caltech's acceptance rate is approximately 2.6–3% — the most selective in this entire series. Reach out for personalised application strategy guidance.

Requirement	CBSE / Indian State Boards	Cambridge A Level
Boards Accepted	CBSE, ICSE and all Indian State Boards accepted — Caltech reviews every applicant in the context of their own school and country. There is no published list of "acceptable" boards and no fixed percentage cut-off.	Cambridge International AS & A Level fully accepted and well understood by Caltech's admissions committee, which reviews thousands of international applications each year.
Academic Bar	No official minimum, but competitive applicants are consistently in the top 1% of their school — 99% of admitted students nationally rank in the top 10% of their graduating class. Depth in Maths and Physics matters far more than breadth across many subjects.	A*A*A to A*AA typical, with A* in Mathematics and Further Maths/Physics essentially expected for competitive applicants.
Required Coursework	Highest-level Mathematics available (calculus essential) + at least one year each of Physics and Chemistry + advanced English. If your school cannot offer calculus, physics or chemistry, Caltech accepts external examination scores or certification as substitutes — document the gap with your counsellor.	A Level Mathematics (Further Maths strongly recommended for Engineering/Physics/CS) + Physics + Chemistry where relevant to the intended area of study.
Standardised Tests	SAT or ACT required (reinstated from Fall 2025 entry). No official minimum, but admitted students typically score 1530+ SAT (near-perfect 790–800 Math) or 35+ ACT. SAT Subject Tests are not required (discontinued since 2020). JEE, NEET or any Indian entrance-exam rank is not required or considered.	Same requirement — SAT or ACT regardless of qualification. A Level results do not substitute for the SAT/ACT requirement.
English Proficiency	Required for all international applicants unless English is the medium of instruction at your secondary school — in that case it is strongly recommended but not mandatory. If required: IELTS 7.0+, TOEFL iBT 100+, or Duolingo English Test 130+.	Cambridge A Level taught in English medium generally satisfies the exemption; strongly recommended to submit a score regardless for a stronger file.
Essays	Common Application personal essay + Caltech-specific supplemental essays (100–250 words each) exploring STEM interests in real depth. Caltech's own guidance: "there is no way to write about too much STEM" — lean fully into technical curiosity rather than broad achievements.	Same essays and same advice apply to all applicants regardless of board.
Teacher Recommendations	2 required: one from a STEM teacher (Maths, Physics, Chemistry or Biology) and one from a Humanities/Social Science teacher (English, History, Government or Economics).	Same requirement for all applicants.
Application Portal	Common Application or QuestBridge (for students from low-income backgrounds, due end of September) — Caltech has no preference between the two. Application fee: USD 75; waived automatically for financial hardship. Caltech does not use UCAS.	Same — all applicants use Common App or QuestBridge.
Restrictive Early Action (REA)	Deadline: November 1 | Decision: mid-December | Non-binding — you may decline even if admitted, and compare offers until May 1. Restricts you from applying Early Action/Early Decision to other private universities (with some public-university exceptions).	Same REA restrictions apply to all applicants.
Regular Decision (RD)	Deadline: January 5 | Decision: mid-March | No restrictions on other applications.	Same deadline for all applicants.
Financial Aid (International) — Critical	Caltech is need-aware for international applicants (need-blind only for US citizens/permanent residents). The most important rule in this table: international citizens who apply REA are not eligible for financial aid at all — aid is only available to international students who apply Regular Decision. If your family will need aid, you must apply RD, not REA. You must also declare your intent to apply for aid at your very first application; if you do not apply for or receive aid in your first year, you may never apply for aid at Caltech again.	Same rule applies to all international applicants regardless of qualification — the REA-blocks-aid rule is not board-specific.
If Admitted With Aid	Caltech commits to meeting 100% of demonstrated financial need, primarily through grants. Average grant aid (Fall 2024): approximately USD 73,000/year. Approximately 60% of all students receive institutional aid. Families earning under USD 100,000/year are typically close to fully covered. Caltech offers no merit scholarships — all aid is need-based only.	Same policy for all admitted international students.
Visa	F-1 Student Visa — Caltech issues the I-20 after admission and deposit. As with all US F-1 visas from June 2025 onward, applicants must set all social media profiles to public before the visa interview; plan 5–6 months for processing. India is not on the current US travel ban list.	Same process for all international students.

Voices from Caltech — Indian Students and Alumni

"Caltech is exceptionally diverse, with a variety of international organisations, faculty and events… I have found the Caltech community to be so close-knit."

— Indian undergraduate student, Caltech | "International perspective: an Indian student in the United States," Times Higher Education Student, 2023

Describing his Caltech years as a "life-changing experience," rooted in the deep trust the Institute placed in its students — a principle he carried into his own career training generations of Indian engineers.

— Dr. Sudhir Kumar Jain, India, Caltech PhD in Earthquake Engineering (1983) | Padma Shri awardee; Founding Director, IIT Gandhinagar; former Vice Chancellor, Banaras Hindu University | Caltech Distinguished Alumni Award 2022

Why Should Your Child Consider Caltech?

1. QS #7 Globally — The Highest Nobel-Laureate Density of Any University on Earth

Caltech holds #7 globally in QS 2027 with a score of 96.6, and has held a top-10 QS position continuously since 2012. But the number that truly captures Caltech is this: with only ~1,000 undergraduates and roughly 2,400 students in total, its alumni and faculty have won 39+ Nobel Prizes, 1 Fields Medal, 6 Turing Awards, and 71 US National Medals of Science or Technology. As one US student review puts it, at Caltech "someone you meet in your time here will more likely than not be a Nobel laureate." The 3:1 student-faculty ratio — the most intimate of any university in this series — means undergraduates work directly alongside the same faculty conducting this Nobel-calibre research, not with teaching assistants several steps removed. Caltech also manages NASA's Jet Propulsion Laboratory (JPL), the centre for America's robotic exploration of the solar system — undergraduates have direct pathways into active interplanetary missions from their very first year.

2. A STEM-Only Core Curriculum — Depth Over Breadth, By Design

Every Caltech undergraduate, whatever they eventually major in, completes the same foundational sequence in mathematics, physics and chemistry — there is no path to a Caltech degree that avoids rigorous science and maths. Students do not declare a major until the end of their first year, giving them a full year to explore the six academic divisions (Biology and Biological Engineering; Chemistry and Chemical Engineering; Engineering and Applied Science; Geology and Planetary Sciences; Humanities and Social Sciences; and Physics, Mathematics and Astronomy) before committing. Around 80% of Caltech undergraduates conduct real research, often starting in their first year through the Summer Undergraduate Research Fellowship (SURF) programme, writing genuine research proposals and presenting findings alongside faculty mentors. Housing is guaranteed for all first-years through eight distinctive undergraduate Houses (not typical dormitories), each with its own traditions and governance — a structure that fosters the tight-knit, collaborative culture Caltech is known for, reinforced by an Honor Code that governs academic life campus-wide.

3. Financial Aid — Generous If Admitted, But One Rule Can Disqualify You Entirely

Caltech is need-aware for international students (need-blind only for US citizens and permanent residents) — the same policy structure as Stanford. If admitted with demonstrated need, Caltech commits to meeting 100% of that need, primarily through grants; the average grant award in Fall 2024 was approximately USD 73,000/year, and roughly 60% of all students receive institutional aid. Families earning under USD 100,000/year are typically close to fully covered. However, there is one rule unique to Caltech in this entire series, and it is critical: international citizens who apply Restrictive Early Action are not eligible for financial aid at all. If your family will need aid, your child must apply Regular Decision, not REA — applying early forfeits aid eligibility entirely, with no exceptions. A second rule compounds this: an international student must declare their intent to apply for aid at the time of their very first application; a student who does not apply for or receive aid in their first year may never apply for Caltech aid again, in any later year. Caltech offers no merit scholarships of any kind. Total cost of attendance for 2025–2026 is approximately USD 93,912/year (~INR 88 lakhs at ~USD 94/INR) for students living on campus.

4. Caltech and India — A Quiet But Deep Connection

India's presence at Caltech runs through some of its most consequential alumni. Dr. Sudhir Kumar Jain earned his PhD in Earthquake Engineering at Caltech in 1983 and went on to become India's preeminent earthquake engineer — founding director of IIT Gandhinagar, later Vice Chancellor of Banaras Hindu University, and a recipient of the Padma Shri, one of India's highest civilian honours, for developing the seismic building codes that protect millions of Indian structures today. On campus, the Organization of the Associated Students of the Indian Subcontinent (OASIS) is the cultural home for Indian and South Asian students — hosting Diwali celebrations, Holi colour festivals, and Republic Day and Independence Day flag-hoisting ceremonies, while Caltech Dhamaka, the campus's co-ed Bollywood fusion dance team, performs at the annual OASIS culture show. Current students speak of a campus so tightly knit that the distinction between "international" and "domestic" student barely registers day to day — a genuine comfort for Indian families considering a campus of this size and intensity for the first time.

What Parents Should Know

• Critical: international applicants who apply Restrictive Early Action (November 1) are not eligible for any financial aid. If your family will need aid, apply Regular Decision (January 5) instead — this single rule can silently disqualify a family from aid they were counting on
• A second rule: you must declare intent to apply for aid at your very first Caltech application. If you skip applying for aid in year one, you cannot apply for Caltech aid in any later year — no exceptions
• Total cost of attendance (2025–2026): approximately USD 93,912/year on campus (~INR 88 lakhs at ~USD 94/INR, June 2026); no merit scholarships exist — all aid is need-based only
• If admitted with demonstrated need: 100% met, primarily via grants; average grant Fall 2024 was ~USD 73,000/year; ~60% of all students receive institutional aid; families under USD 100,000 income are typically close to fully covered
• SAT or ACT is mandatory (reinstated for Fall 2025 entry); no official minimum but admitted students typically score 1530+ SAT (near-perfect Math) or 35+ ACT; SAT Subject Tests are not required
• JEE, NEET or any Indian entrance-exam rank is explicitly not required or considered — Caltech evaluates school record, SAT/ACT, essays and research curiosity only
• Acceptance rate is approximately 2.6–3% — harder to gain admission to than MIT (~4.5%); this is the most selective university in this entire series
• Fit matters enormously: Caltech has no non-STEM majors and every student completes the same core maths/physics/chemistry sequence regardless of major — this is the right choice only for a genuinely STEM-obsessed student, not a broadly strong all-rounder
• F-1 social media vetting (from June 2025): all F-1 applicants must set social media profiles to public before their visa interview; plan 5–6 months for processing; India is not on the current US travel ban list
• No financial aid is available for international transfer students or 3/2 engineering programme applicants — aid is only available to first-year international applicants
