Although English language learners may speak English on the playground, this does not mean they have mastered the academic and cognitive language of the classroom (Haynes, 2007). This means that neither does education in a private or public institution matter in terms of the acquisition of bilingual skills of students. Studies show that the complex interplay between the input of language, the amount of input, and the age of a person in learning two languages play a vital role in his success at bilingualism.
