Although the use of data is important for informing inclusive practice, research into Australian early childhood educators’ data practice is limited. Types of data collected in early childhood settings and the use of these data were investigated. Surveys completed by 105 early childhood educators across Australia indicated that anecdotal written records, photos, and children’s work samples were the predominant data collection strategies used for both children with and without additional needs. More educators reported that they collected counted or timed behaviour data for children with additional needs than for those without additional needs. One third of educators did not indicate that they collect this type of data. The majority of educators indicated that they value the use of data in their practice, reported that they use data for progress monitoring and modification of activities to meet the needs of individuals with additional needs, and perceived that they were confident in using the data collection strategies that they nominated. The data that these Australian early childhood educators used were predominantly qualitative, suggesting that training is needed for educators to collect and utilise both qualitative and quantitative data to assist with instructional decision-making.
