Price and format
IELTS costs £180-£220 per attempt and takes 2 hours 45 minutes. Duolingo English Test costs $65 per attempt and takes 60 minutes. Neither is inherently better on price alone since each serves a somewhat different primary purpose.
Recognition and best use case
IELTS is best known for uk/australia/canada immigration and study, most widely recognised. Duolingo English Test is best known for university admissions in us/canada, affordable alternative to ielts. Duolingo tends to fit US and Canadian university admissions well, given the 5,000+ institutions now accepting it, while IELTS remains the safer choice for UK visa and immigration purposes where accreditation is legally required.
Weaknesses to know about
IELTS's main drawback: very expensive, requires exam centre, wait for results 13 days. Duolingo English Test's main drawback: expensive ($65), english only, primarily academic use.
Is there a cheaper alternative to both IELTS and Duolingo English Test
If neither exam's formal accreditation is a strict requirement for your situation, an independent CEFR-aligned test like Examinizer offers a faster and considerably cheaper option. It costs €8 for a verified certificate with a QR code, compared to £180-£220 per attempt for IELTS or $65 per attempt for Duolingo English Test, and gives an instant result rather than days or weeks of waiting.
This works well for employer screening, CVs, LinkedIn profiles, and personal tracking, though it does not replace either exam where a specific accreditation is legally required, such as most visa applications or university admissions that name IELTS or Duolingo English Test directly.
