What TOEFL score do you need for Colorado School of Mines?

The undergraduate page's text gives the minimum as "79 or 4.5", while its table for tests after 20 January 2026 shows a total of 4; ask admissions which applies if your total falls between them. Tests must have been taken within the past two years and must not expire during the application process, and undergraduate admissions will superscore section scores across valid tests. The undergraduate page also accepts the TOEFL At-Home Test at the same scores.

The graduate page says scores are valid for two years and that, with multiple valid TOEFL tests, Mines can accept MyBest scores or superscore sections. Graduate applicants may self-report scores, with official scores required on admission. The institution code is 4073.

For comparison, both Mines pages set IELTS at 6.5 overall with no band below 6.0.

Neither page describes conditional admission or a pathway programme. Graduate applicants to an online programme who will study outside the US do not need English scores, and the graduate page lists a small set of waiver circumstances, such as recent degree study in a university-approved country.

Requirements vary by programme and change between admissions cycles. The score that binds you is the one on your Mines programme page and in your offer letter, so check it there before you book a test.
