A1 to C2 is a capability framework, not a guarantee
The CEFR describes stages across listening, speaking, reading and writing: A1 handles familiar information, while C2 represents very high comprehension and expression. A level alone does not prove a number of class hours, a course title or guaranteed short-term outcome.
Set goals through real tasks
Write the tasks needed—introductions, housing communication, class discussion, exam preparation or specialist reading. Then ask how the school's placement test works, weekly hours, homework, class size and whether the course covers those skills.
Spain and Latin American varieties are both resources
Spanish has varied accents, vocabulary and pace. A standard course builds a base, while city life trains listening to different speakers; do not treat one pronunciation as the only correct result.
Measure progress with evidence, not names
Keep placement results, class feedback, writing samples and repeatable speaking-task records. If an official exam is needed, separately check the provider, registration conditions, score use and validity.
Five checks before choosing a course
Confirm current level, target tasks, duration and intensity, school testing method and the actual meaning of any course certificate. Adviser or website wording does not replace the school's written course description.
