Language proficiency is a pillar of K-12 education, as schools aim to equip students with the ability to communicate in real-world situations. Modern assessments go beyond just grammar and vocabulary, evaluating how firm a grasp learners have of language across listening, reading, writing and speaking. Selecting the right language proficiency test is important for educators and administrators. However, this is easier said than done, as there are a handful of standout tests that differ in key areas.
These three top tests were selected based on their relevance to K-12 learners, the range of skills they assess, how well they can be implemented into an educational setting and their overall reputation.
