How is Duolingo language proficiency calculated

English learning tree


I have completed the English learning tree. Additional learning steps from the Lingot shop as well.

Will the learning tree be supplemented by further steps at any point in time? Is there any information about this; or can I still load something myself somewhere?


hello a question why did I finish level 15 and the learning tree only 2/3? You have level 14 or the level automatically falls back if you don't practice for a while, lg


In my opinion, the level is partly dependent on how many XP points have been achieved through the individual learning steps. Since I took a lot of shortcuts in the beginning, my XP number is not particularly high. At the moment I need 1,500 additional XP points to reach a new level. In fact, I only started on January 1st, 2016 and have a 108-day streak (so no break).


That's true. I finished the learning tree at level 10 because I shortened everything that was possible. I've already done some repetitions. As a result, I've now reached level 12. I would like to know how high you can drive the fluency percentages. I answer at least 95% of the questions correctly, but only a small percentage is added. I believe that from this point on you have to get a lot of xp points in order to be able to improve the percentages. I'm now at 71%.


"I finished the learning tree at level 10 because I shortened everything that was possible."

Me too.

"I would like to know how high you can drive the fluency percentages. I answer at least 95% of the questions correctly, but only a few percentages are added. I believe that from this point on you have to get a lot of xp points, in order to be able to improve the percentages. I'm now at 71%. "

Me too. ;-) Or something in the shoot, and nothing has changed for me since then. If I'm not mistaken, there was even something of ~ 70% when I was halfway through the tree. May I ask why is this so important to you? This "fluency" statement has no comprehensible meaning beyond Duolingo, and I think it simply has to do with the fact that you and I have not yet seen many (available) sentences in the course; the system assumes that the words / phrases contained there would be new to us in any case. ;) After all, even Duolingo cannot clairvoyance. With the XP points, the m.W. on the other hand, nothing to be done, but I am happy to be corrected.


Hello purple light,

Do you want to know why I care? Because I always want to achieve 100% when 100% is to be achieved. Just to prevent misunderstandings. In this case I mean the 100% percent that duolingo contains and asks for. For example, you don't climb Mount Everest and then say 10 meters below the summit: So, it's pretty up here, I can save the rest. I realize that my English is not 100% fluent and error-free. It can't be because English is not my mother tongue, nor is it my everyday language. I signed up for duolingo 20 days ago and finished the English learning tree within 24 hours. Since then I have been answering all the questions that are necessary to keep all the lessons on the gold level. Although I answer all questions against the clock, I hardly make any mistakes. (If so, then more likely a typo) Still, I've only been able to improve by 1 or 2 percentage points since day one. The interesting thing for me is how duolingo calculates the value. It does not seem to have too much vocabulary either, since the test questions are often repeated even though they have already been answered correctly several times. As a result, I ask myself the following question. How does duolingo know the percentage of my knowledge of the language to be learned if I can answer everything that is queried and difficult vocabulary is not queried at all? But no matter, because I've been learning Spanish for 19 days with English as the source language. Here I'm only at 32%. And in my opinion, they are far too high. When I watch Spanish videos on Youtube or something, I feel like I understand 10% at most.


Well, as I said, I don't know how this is calculated, but I don't care too much because it obviously has, or can have, no relation to actual or "only" passive language competence. I understand the spoken word as well as the most complex texts and those with lush technical language. Vocabulary, such as textbooks and articles in scientific journals, in English. Speech too practical ~ 99%. When working through the local curriculum, I basically made no mistakes, except for a few typing mistakes or overly liberal translations. According to Duolingo, I am only just over 70% "fluent" even when measured against the very simple examples. On the other hand, I've only just started Italian, a tired handful of lessons have been completed and I'm already at a proud 17%. Amazing considering the fact that I don't understand a single natural sentence in Italian - not written, and certainly not spoken - and in my case I wouldn't even speak of 10% understanding. Are probably around 5%. So the perceived discrepancy is similar to your case with Spanish.

If it is as I assume and this value is simply a result of the tasks that have not yet been seen, it could take a while before you achieve full fluency there. If any. Because the sentences seem to me to come at random, that's why we keep seeing the same as soon as we know most of them. You can decide for yourself whether or not it will bring you to repeat the same questions over and over again until a new one comes up, just to see 100% at some point.


you will probably not like my answer: just keep going and you will see how it works :) it's all about learning with joy!
