Curious how our students celebrated the last day of school? Let’s take a look.
Wearing pajamas marked a fun and cozy way to end the school year for our Nursery 2 students. With their comfiest outfits and favorite dolls, they spent the day dancing, watching a movie together, and making wonderful memories with their classmates.
As the school year comes to a close, we are proud to be part of our students' learning journey and witness their progress throughout the year. Wishing them all the best as they begin their next chapter.
