Global Scale of English (GSE) is a test for learners of English as a second or foreign language. The GSE is a list of can-do statements based on the Common European Framework of Reference (CEFR) for English. Learners' abilities are rated on a 10-to-90 point scale for each of the four basic skills (speaking, listening, reading, and writing). A learner reaches a level on the scale when she or he can correctly perform 50% of the can-do tasks at that level. The education company Pearson PLC developed the scale.
