School Excuse Sample Letter
TO: [school official]
RE: [students name and vacation dates]
Please be advised that [student] will be out of school during the week of [date]. We ask that his absences be excused.
The reason for [student]'s absence is that our family will be out of the state during this week. While we are gone, we will be visiting Walt Disney World. We believe that [student] will be learning many things during this trip and that his education will continue in his absence from school.
Some things [student] will learn about:
Different cultures of the world, including architecture, language, diet, and dress, by visiting the different countries in the Epcot World Showcase (Japan, China, Germany, Mexico, Norway, Canada, France, etc.) [student] will have the chance to explore the exhibits for each country and speak with natives from each country who work as cast members.
American history by viewing the Hall of Presidents presentation in the Magic Kingdom and the American Adventure show in Epcot.
Nature and conservation at Animal Kingdom.
Science by exploring the Mission:Space ride in Epcot where he will have a chance to see and feel what it would be like to travel by rocket to Mars and by experiencing the Universe of Energy exhibit which teaches about fossil fuels, energy, and conservation.
Economics by managing his own spending money and making budget decisions on how to spend his money.
[student] will also be learning about map reading by navigating in and to the different theme parks, as well as the resorts and water parks via the Disney bus system, sociological aspects of crowds including patterns and behavior, physics of the different rides, breakthroughs in technology at the Innoventions computer lab in Epcot, art and animation and the history of film, and mathematics.
We believe this will be a wonderful and educational experience for [student] and hope you agree not to charge him with unexcused absences as a result. If it is possible for [student] to take any assignments with him to be turned in when we return or to turn in before we leave any work that will be due while he is gone, please let us know as soon as possible.
Thank you for your attention to this. If you have any questions or need any further information, please feel free to contact me.
