As a professional commitment, we have developed School Report Cards through which one can search 1.5 million schools in INDIA on different parameters (1 to 12 Standards)

Each school is given 11-digit unique identification code. Perhaps, this is the only site of its nature.
Please visit and have a look.
Thanks
