The Babbel Method’s effectiveness is scientifically proven. In a study by the City University of New York in 2016, 81% of the participants confirmed that they were able to improve their communication skills in Spanish. After just 15 hours of learning with Babbel, the participants were able to reach a level equivalent to one semester of college Spanish.In 2019, a study by Michigan State University focused on the effectiveness of the Babbel Method: 97% of participants who learned for at least 10 hours with Babbel were able to improve their test scores in grammar and vocabulary, and 73% also improved their speaking skills.
