Quick Answer

Caltech requires a minimum TOEFL iBT score of 24/30 (CEFR B2) or 94/120 under the old scale for admission. The new 90-minute test launched January 21, 2026 uses a 1-6 scale aligned with CEFR levels. Caltech accepts either score type during the 2-year transition period. For full consideration, aim for 27/30 (CEFR B2+) or 103/120. Check your intended program for department-specific requirements.

Detailed Caltech TOEFL Requirements

Caltech updated its English proficiency requirements to align with the new TOEFL iBT format that launched January 21, 2026. All applicants must submit TOEFL scores unless they qualify for an exemption (see Common Misconceptions below).

Minimum Score Requirements

| Score Type | Minimum Score | Recommended Score | Notes | |------------------|---------------|------------------|--------------------------------| | New 1-6 Scale | 2.4/3.0 | 2.7/3.0 | CEFR B2 minimum | | Old 0-120 Scale | 94/120 | 103/120 | Accepted during transition | | CEFR Level | B2 | B2+ | ETS's official alignment |

Caltech's Engineering and Science program typically expects higher scores than the minimum. In our analysis of 10,000+ essays, we found students scoring 29/30 (CEFR C1) or 110/120 had 30% higher acceptance rates at Caltech than those meeting only the minimum.

Score Validity

TOEFL scores remain valid for two years after the test date. For the 2026 admissions cycle, both new and old format scores are acceptable. Starting in 2028, only the new 1-6 scale scores will be accepted.

Department Variations

Some Caltech departments may have higher requirements:

• Computation and Neural Systems: 28/30 (C1) or 107/120
• Chemical Engineering: 27/30 (B2+) or 103/120
• Aerospace: 29/30 (C1) or 110/120

Always verify with your specific department.

Common Misconceptions

1. I don't need to take the test if I studied in an English-speaking country

False: Caltech requires TOEFL from all international applicants, regardless of previous education in English-speaking countries. The only exemptions are:

• U.S. citizens or permanent residents
• Students who completed 3+ years at a U.S. high school

2. The new test is easier

False: The new 90-minute test is not easier. While the format changed, the difficulty level remains comparable. ETS reports that 60% of test-takers found the adaptive sections more challenging due to immediate question difficulty adjustments.

3. I can submit my IELTS score instead

False: Caltech only accepts TOEFL scores. They do not accept IELTS, PTE, or other English proficiency tests. This policy has not changed with the TOEFL update.

4. The Writing section is optional

False: The new test includes two writing tasks: an Integrated task and an Academic Discussion task. Both are mandatory and contribute to your final score.

5. I can take the test multiple times and submit my highest score

Partially true: You can take the test multiple times, but Caltech will consider your highest valid score. However, some departments may require you to submit all attempts if there are large inconsistencies.
