Subscores and program differences
Check Reading, Listening, Writing, and Speaking individually against 110. Purdue describes these DET scores as typical applicant guidance; its application review is holistic. This profile does not cover graduate admission or Purdue Fort Wayne.
Sending your result and checking dates
Results must come from a test taken within the past two years. Send certified DET results to Purdue University Undergraduate Admissions. Applicants admitted using self-reported results must provide official reports when accepting their offer.
Confirm the current instructions for your program and intake on the official Purdue admissions page.
How the DET score compares with IELTS
DET 115 compares with IELTS 6.0 in Duolingo’s overall concordance. Purdue sets its own test requirements, shown above; those requirements take precedence for your application.

Practice around your remaining requirement
A 115 overall practice estimate can hide an uneven skill profile. Review all four individual skills and choose focused work for any below the published 110 benchmark.
PrepEx scores are independent practice estimates, not official DET results. Meeting a test threshold does not guarantee admission.
