The when, why and how of English learning after class debate

After the class debate, our doubt about which age is the best to start learning English continues more or less the same way. However, we realised that exposure time and quality both together are the key. Obviously, there could be several combinations of starting age and hours per week given to English in order to ensure the same overall exposure to the language, so there isn't just one right way around. But it is something to take into account that high exposure will not necessarily bring higher competence.

Nevertheless, we agree that Basque language is the priority here and starting learning English at the age of 4 gives a good exposure to English while not harming Basque language. Therefore, we have decided our starting age will be 4 years old.
