Dress Code
-
AC3s & Pre-K: No formal dress code is required. Clothing and shoes appropriate for school and active, outdoor play is recommended. Shorts and denim are acceptable.
-
Lower School: Navy, blue, white, and khaki dress code. You can visit landsend.com/school and type in Allendale Columbia's school number (900085473) for a helpful reference, but you are not required to purchase from Lands' End.
-
Middle & Upper School: The dress code allows options from casual to professional. We trust students, with faculty and family guidance, to dress appropriately for different situations. For a typical school day, students may choose relaxed and comfortable clothing, or more professional dress if they prefer. For a presentation or a field trip, students may be required to dress more professionally. On the other hand, community service or outdoor activities may call for more casual, active clothes. At all times, students should dress in a way that shows respect to others and to themselves.
-
Students enjoy AC Spirit Day the last Friday of each month. On Spirit Day, they may wear jeans with an Allendale Columbia School top or school colors.
Each year, we create a new student slideshow to help faculty and staff get to know our new students before the first day of school. This is not required, but we would love to include a recent picture of your child(ren)! If you wish to participate, please send your photo to asomaskanda@allendalecolumbia.org.
