Haridasa Thakura never attended any school.

Srila Narayana Maharaja: We know that Haridasa Thakura never attended any school. Was he admitted in any school since his birth? Never. Yet, Mahaprabhu made him Namacarya Haridasa Thakura. Why? He was qualified to be a Namacarya. If anyone has faith in the Name, thinking that by chanting the Name his life will be successful, and he is chanting and rembering with this faith, then he has no need to 

go to any school, any college, or anywhere else. Has Srila Swami Maharaja told anywhere that you should go to this bad university or that bad university? What will be the result? Those who are going will be like historians. They will not believe in God. They will not believe in Name and harikatha. They will not believe that Caitanya Mahaprabhu came from Goloka Vrndavan (Svetedvipa). They will think, “Krsna was not God.” Gradually this belief will come. They will compare Caitanya Mahaprabhu with Buddha.
