Our aim is to foster and celebrate children’s natural qualities through an innovative and creative curriculum that ensures the best learning and teaching practices in Early Childhood.


  • Play. At SEK-El Castillo, play is the vehicle for children’s learning and all-round development with the aim of fostering student agency and where they can build meaning by interacting with the physical and social world and through active methodologies.
  • Relationships and emotional development. Our programmes encourage and promote positive relationships among the entire educational community.
  • Inquiry. Learning is developed through inquiry, which arises from exploring different environments, investigating materials, playing, and interacting with others. Authentic experiences that cater to the interests and needs of the child.
  • Creative expression and the arts. The holistic development of children is enriched through these languages, which they use to communicate and expand their ideas, in addition to develop skills and attitudes.
  • Learning spaces. A fundamental part of Early Childhood are the school’s learning spaces, interconnected indoor spaces with exits to the outdoors and natural environments. Versatile spaces that allow designing experiences and developing skills and different learning approaches.


Our Early Childhood years span two stages: NURSERY, from 4 months to 3 years old and PRESCHOOL from 3 to 6 years of age. Main components of learning at this stage:

  • Spanish curriculum and International Baccalaureate Primary Years Programme.
  • The NEASC accreditation guarantees the quality of our practices and the impact they have on learning.
