Welcome to AC

Congratulations on your acceptance to AC! We look forward to welcoming you to school.
Please review and complete the important information on this page, to ensure you have a smooth start. If you have any questions, please contact us at 585.641.5344 or email admissions@allendalecolumbia.org.

Information for New Families

MyACS School Portal
MyACS is our school's online portal. It is a one-stop-shop for all AC-related information, including student schedules, grade reports, news, calendars, and more. Be sure to bookmark this page and remember your password as you will need to reference it throughout the year! You can also easily access MyACS by clicking the shortcut link on our homepage.

Emergency Communications
In the event of a snow day or an emergency on campus, Allendale Columbia School will communicate with families via School Messenger. Please text "Y" to 67587 to opt-in to receive emergency text notifications. Also, please be sure to have your cell phone listed as your primary contact in MyACS to ensure you receive emergency calls.

Transportation
2026-2027 School Calendar 
Most districts request that transportation forms be completed by April 1st. Please contact your home district to make sure you are all set with transportation, if you plan on using your district's bus service. Additional drop-off and pick-up information can be found here.

Health Forms & Immunization Requirements
A Health Appraisal and Immunization form must be completed by your pediatrician and sent to the Admissions Office (fax 585.249.0230) prior to your child(ren)'s first day of school. Please also review our Medication Policy and over-the-counter medications form, which can be used for children to self-carry any OTC medications as they need.

Rainbow Room (AC3s - Grade 5)
Rainbow Room is AC's wrap-around care for families of children in AC3s - Grade 5 who are interested in childcare after the regular school day (available from 3:00 p.m. - 6:00 p.m.) and/or vacation day care. Please note vacation days are not included in the after school care package. Please create an account with Campbrain to register. Once you have created an account and are on the dashboard, please click "enrollment" on the left side and scroll down to your child(ren). You will be given a list of Rainbow Room options for the full year and vacation days. They are listed in alphabetical order. If you have any questions or concerns, please contact bwheeler@allendalecolumbia.org. 

Academic Calendar
2026-2027 School Calendar

Learning Platforms 
AC uses Google Workspace for Education, and we provide and manage a Google account for your child. Learn more about that here.

New AC Little School Families
2026-2027 Little School Calendar
All families who are new to the AC Little School must complete and submit the online profile update and acknowledgement forms before their first day.  These forms can be viewed and completed in the MyACS Parent Portal.

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. 
Send us a picture!
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.
