In an education sector, skilled & experienced teachers are the most important issues to provide quality education. BSDI never compromise in this regard. In order to have the best teachers, BSDI maintains a systematic approach. First, the candidates have to sit for a written test, then an interview is taken. At last, the candidate has to give 2/3-demonstration class from which we take the feedback from the students. And finally, the candidate is selected or rejected. We always give emphasis on the candidate.
