A letter requesting a transfer certificate, so that your child can be transferred to another school, does not have to be very long, however it should still be written formally. The letter will need to include your child's name, grade/year that he/she is studying in, a reason for the transfer and the date that your child will be leaving the school.
The structure of the letter should look like this;
To The Principal
(School Name )
Dear Mr/Mrs/Miss or To whom it may concern,
I am requesting you for a transfer certificate for my (name of your child), of (year/grade that your child is studying in at the moment).
My reason for requesting a transfer certificate is that we are moving to another country/city due to work and I would like (the name of your child) to carry on with his/her education.
I am also grateful for the support that you and your staff have provide for my child. Thank you.
Yours Sincerely or Yours Faithfully,
(Your contact details, such as your telephone number, email address and home address.)
When writing the date, the month should be written as a word, for example 21st March 2011. When you are starting starting the letter off with 'Dear Mr/Mrs', this should only be used if you known their last name and if you are addressing a woman and you are not sure whether she is a 'Miss' or 'Mrs' use 'Ms', and 'To whom is may concern' when you do not know their name. When you are signing off your letter, use 'Yours Sincerely' if you know their name and have used 'Dear Mr/Mrs', and 'Yours Faithfully' if you do not know their names and have used 'To whom it may concern.' When writing a formal letter, your first paragraph should explain what the letter is about, and get straight to the point, and your last paragraph should explain what actions are expected to be made.
