Use the format of writing a formal letter like business letters. Specify the address of the authority to whom you want to address the issues. Write both addresses in block indentation neatly to make your letter appeasing to the eye. Punctuate your addresses well and use a formal salutation thereafter.
State plainly the reason for your complaint. Keep the language simple and clear. Make sure your language is persuasive to the reader. Avoid making rude remarks that may alter the result you expect from your complaint letter. Stick to the point of your complaint throughout the letter. Concise letters are easily understood and the issues are in turn easy to look into.
Indicate clearly what you want addressed by the school's administration. Express in polite terms how you would like the issues addressed and the period you want the matter looked into. Give a reasonable amount of time because the school administration has a workload to handle. Refer to the students' opinion as a whole throughout the complaint letter. Avoid using your personal opinion of the situation when writing the letter. Be positive throughout your article to encourage a positive result from the reader of your complaint letter.
Use complimentary remarks at the conclusion of your complaint letter. Sign off at the end of the letter using your official name. Avoid using aliases or nicknames when you sign off. State your position in the student body whether a class representative or the student president.
