Every month, since May 2021, Duolingo releases a new Monthly Challenge, which you will find in the quests section (Chest icon).

To achieve a monthly challenge Badge, you will need to complete one of the following, depending on the challenge:
  • Complete a certain number of quests within a month. These include Daily Quests https://fitatotto.nl/portfolio/duolingo-daily-quests/ and/or Friends Quests, which we will have a closer look at in the near future.
  • Earn 1000XP within a month. You can earn XP in various ways: through completing lessons, through practice sessions, timed challenges, and more.

You can track your progress in the Quests section Goals tab.

When you complete a monthly challenge, your Badge will become visible in the Badges tab.
