Can I use scores from the Test of English as a Foreign Language (TOEFL), the International English Language Testing System (IELTS), or Duolingo English Test (DET) to satisfy the ELWR?

No, not for the Entry Level Writing Requirement. TOEFL, IELTS, or DET scores may be used to demonstrate English language proficiency, but are not acceptable for the ELWR.

You can see which exams may be used to satisfy the ELWR on the UC ELWR website.
