This school was initially started in a rented building in the year 1998 on the Station Road, Arrah. In the mean time, the D.A.V. Trust and Management Society got land on lease for 25 years from Late Baldev Sahu’s family at Mill Road, Nawada, Arrah, Bhojpur, Bihar in 2000. B.S.D.A.V. Public school was started at Mill Road, Nawada, Ara by the D.A.V. Management in the year 2001. It has its own  big palatial School building. It has a rich library, computer lab and several other sophisticated  equipments related to Scholastic and  co- Scholastic activities to face the new challenges in the field of education in this changing world of science and technology. It has a team of highly qualified, experienced and dedicated teachers.  
         Previously it was the feeder branch of the D.A.V. Public School, Dhanupura Ara, Bhojpur,  till March 2006. But now both schools are running separately from 1st April 2006. This school has more than three thousand students.  Students are shifted to DAV Dhanupra after completing education upto class VII. The school runs in two shifts to accommodate students. But due to lack of rooms, we are unable to take new admission which is in heavy demand. So, we are in search of new plot of land to start a new school in this town. 
         In a very short span of time the school has successfully managed to place itself distinctly among the already established educational institutions of the town. Now Bal Dev Sahu DAV Public School, Mill Road, Ara, Bhojpur is one of the most reputed schools of Bihar. It is striving to prepare students having filled with our vedic culture and human values under the shade of holistic  atmosphere of the school. Some activities and achievements of this school are as follows :-
 (A)    EDUCATIONAL TOURS :    The School plans picnics and educational tours for the students. They are taken to Historical Places, Museums, Factories, research Institutions Dairy Project, Water Purifier Center,  Post Office, Science City, Bank etc. to give them a first hand knowledge.
(B)    EXHIBITIONS :     Art & Craft Exhibition and  Science Exhibition are held on     regular basis.
