To account for additional scored test items and scoring methodology, the Duolingo English Test has a new scale out of 160 in 5 point increments.
Our research team and technical advisory board, comprised of experts in the fields of language testing and psychometrics, developed a scale that has higher confidence at individual score points, helps reduce misinterpretation of scores, and distinguishes Duolingo from other tests.
The former 100-point scale was commonly misunderstood to be a percentage correct or a linear mapping of test takers’ responses. For example, scoring a 70 on the 100-point scale was often equated to getting 30% incorrect or earning a “C-”. The new scale helps mitigate this misinterpretation.
When making high-stakes decisions, institutions should always also consider other factors like GPA, other test scores, recommendations, or interviews. As a best practice, when setting minimum thresholds, it is useful to set scores flexibly and conduct periodic reviews of score requirements.
