What is the Cambridge English Corpus?

It is our main research tool, designed by us and completely unique. It gives us a clear view of how the English language is currently used all around the world: how it’s spoken, how it’s written in different contexts, how it evolves and what errors Spanish people make.

Specialists in English for Spanish Speakers

Every year, more than 200,000 Spanish people take one of the Cambridge exams.

We are the only publishing house in the world with access to the information generated by these exams: what they get right, what they get wrong and how to stop those errors from occurring. We statistically analyse this extremely valuable information in order to make the most effective English teaching methods that you can find.
