Fluency is an estimated measure of proficiency of the vocabulary, grammar, comprehension and the ability to produce the language[1][2]. As of November 2016, the fluence score is only available in Spanish, German, French, Portuguese, Italian, and English[3].

Metrics used Edit

The metrics used to estimate user's fluency include[4]:

  • Progress in a course
  • Accuracy of the answers
  • Frequency of practice
  • Words learnt
  • Importance of words

Score Edit

The fluency score will either increase through continued practice or decrease if the user doesn't regularly practice. As of July 2016 one can only reach a fluency as high as  50-60%, which according to Duolingo is equivalent to an advanced proficiency in the Duolingo Test Center [1].
