Sarah Brown

Sarah Brown

Group Head of Learning and Learning Improvement

Sarah’s adventures into the world of education began after careers in journalism, music PR and the police force sparked a curiosity for life-long and life-wide learning.



An interest in learning and the brain led to a natural move into primary education, where she spent years as a teacher.

A passion for curriculum design opened the door to many happy years working and learning with the International Primary Curriculum and leading professional development and accreditation for schools around the world, before becoming head of programme.



Before joining International Schools Partnership (ISP) in 2019, Sarah moved to the Netherlands to collaborate on the first comprehensive review of the International Baccalaureate’s Primary Years Programme, evaluating the philosophy and pedagogy of the framework and developing support materials, videos and podcasts. During this time, she deepened her interest in the fields of educational neuroscience and student wellbeing, both of which are the research focus for her doctorate studies at the University of Bath.



Sarah loves creating and curating events and experiences where diverse groups of people can learn – and ideally laugh – together. Whether that’s online or face to face, involves education, music, immersive theatre, improvisation, philosophy or film nights, bringing people together is what makes her happy. And Japan – from the sake to the stationery, the gardens to the green tea, the karaoke to the cat faces – Japan makes her really happy!

Marianne is an experienced program developer and workshop leader. She has also led a successful schoolwide CIS-NEASC accreditation process and has been on visiting accreditation committees to other international schools.



Through Marianne’s diverse experience in well-established Pre-K to 12 international schools such as the United World College of South East Asia, International School of Manila, Shekou International School, and Anglo-American School of Sofia, she has learned the value of collaboration, trust and relationship building in engaging and empowering learners.
