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 fluency score was only available in Spanish, German, French, Portuguese, Italian, and English[3] but since then the fluency score has also been made available in Polish, Danish, and Swedish.

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 learned; and
  • 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 October 2017 one can only reach a fluency as high as 65%, which according to Duolingo is equivalent to an advanced proficiency in the Duolingo Test Center [1].
