SIELE is the Servicio Internacional de Evaluación de la Lengua Española, a system that assesses and certifies Spanish language proficiency, using electronic means, aimed at students and professionals, on all five continents.
It is promoted by the Instituto Cervantes, the Universidad Nacional Autónoma de México, the Universidad de Salamanca and the Universidad de Buenos Aires, which guarantees the quality of the tests and takes into account all linguistic variations from a pan-Hispanic point of view.
SIELE certifies the degree of competencies in the Spanish language through four tests that evaluate different linguistic skills: Reading comprehension, Listening comprehension, Written expression and interaction, and Oral expression and interaction; and the scoring corresponds to the European Council's Common European Framework of Reference for Languages (CEFR).
