The International School of Dublin (ISD) serves students aged 3.5 to 12. Founded in 2007 as Ireland's first accredited International Baccalaureate Primary Years Programme (IB PYP) school, ISD employs an inquiry-based curriculum built around six transdisciplinary themes. The daily schedule includes seven periods, integrating Spanish, physical education, and performing arts classes alongside core subjects. The school caps class sizes at 18 for Kindergarten and 20 for Grades 1-6, maintaining an average of 12 students per class to ensure individualized attention. Students utilize a blended learning approach, incorporating virtual lessons to develop technology skills. Extracurricular options run daily until 6:00 pm, offering over 30 activities including capoeira, Japanese, and sewing. ISD fosters student agency through initiatives like the Student Council. The community celebrates learning outcomes through "End of Unit Sharing," an interactive afternoon where students present their recent inquiries to their parents, acting as the teachers.
