This dataset consists of early learning development data collected using the Early Learning Outcomes Measure (ELOM) assessment tool. The ELOM was developed on behalf of Innovation Edge by Andrew Dawes, Linda Biersteker, Elizabeth Girdwood, Matthew Snelling and Colin Tedoux. Prior to the development of this tool, there was no validated South African instrument for measuring programme performance against early learning development standards. The ELOM is an age-normed, standardised instrument for use with children in two age groups: 50-59 months and 60-69 months. The tool covers both direct assessment of children’s performance and an assessment of the child’s social and emotional functioning and orientation to tasks.
