In recent developments, early childhood education in Saudi Arabia have captured political and governmental interests, conceiving the promising returns of investing in early years. This research has adopted an analytical descriptive approach through content analysis of curriculum philosophy (theories and principles) of three models of early childhood curricula. They were chosen deliberately, considering the elements of the curriculum, effectiveness in implementation and or achieving the desired learning outcomes. The selected curricula include, HighScope, Foundation Stage, and Te Whariki. The analysis concludes that there is a general agreement about the structure and elements of EC curriculum. Perspective of children as learners, teachers' roles, learning environment are well profound in the three curricula supported by theoretical and empirical evidence. Nevertheless, challenges are still considered as opportunities for revising and evaluating our beliefs and understandings in order to maintain the improvements in ECE profession and to cope with the education reform in Saudi Arabia.
