Find the comparison for your DET score
This compares official-test score scales. It does not turn a PrepEx practice estimate into an official result or replace a test the university requests.
Check the institution’s own DET requirement
These 9 profiles cover specific undergraduate policies. Reaching a listed overall benchmark does not establish admission eligibility: program rules, subscores, test dates, and the rest of your application still matter.

How to use this comparison
A concordance compares results across groups of test takers. It does not guarantee the IELTS band you would earn, certify proficiency, or override an institution’s policy. Do not use this overall table to convert a Writing, Speaking, Reading, Listening, or Production subscore.
