Mark your diary: First day of school is Monday 18th August 2025!
At ACS Hillingdon, we host a variety of events throughout the year to welcome new families, support our students, and help parents better understand the different aspects of school life.
Below is a list of key events taking place in August and September—these are some of the most important opportunities for you to connect with our community and get a strong start to the year.
To stay up to date with everything happening at school, we encourage you to subscribe to the school calendar or regularly check your child’s schedule through PowerSchool.
Please note that the events listed here are just the beginning! More activities and opportunities will be shared with you throughout the year by our faculty, PSO liaison officers, and your grade-level parent representatives.
