Data-driven decision making (DDDM) is an increasingly important innovation at all levels of the education system, including early childhood care and education (ECCE). This multisite, qualitative case study was designed to investigate the practice and ideology of data use at early childhood centres in the Caribbean island of Tobago. We analyzed DDDM using a sociological lens of practice and ideology as described by Lofland, Snow, Anderson, and Lofland (2006).
