Since, you have selected another school, so you have to mention the reason of doing the same
Is it because of the transfer of the parent?
Yes, it is important and advisable on account of courtesy ground, to mention the reason of switching another school for your child.
Now, I am writing the following letter
City Montessori School,
Subject (Request to issue school leaving certificate of my daughter)
I am X (Your name), guardian of Arpita Sharma , who has recently passed class 8th from your esteemed school. I request you to kindly issue school leaving certificate of my daughter, as we are shifting to a new location and joining a new school in its vicinity
