Writing a leave application for school requires a clear and respectful format. Begin with the date at the top, followed by the recipient’s designation (Class Teacher or Principal). Start your application with a polite salutation, then mention the reason for the leave, specific dates, and any relevant details. Keep the language formal and concise. Request approval and express gratitude for their consideration. End with “Sincerely” or “Yours faithfully,” followed by your name and class details. If required, include a parent or guardian’s signature. This simple yet effective format ensures clear communication and maintains school etiquette.
