HELLO RAJESH !

Its obviously possible for a student to change his school from one KV School to other. For this , you need to get a transfer certificate from your school. You can issue a transfer certificate by writing a letter mentioning reason for school transfer and submit it in school's office. After this you will get a form which you have to fill accurately and completely. It maybe required for future reference. Subsequently, you will get the transfer certificate from your school in a day or two. If you show that transfer certificate in any other K V school, you will get admission there directly.

I hope this helps!
