The effective use of student data can be the impetus for educators to improve learning and wellbeing outcomes, and/or student social and emotional learning. However, simply having data offers very little insight. The value comes from being able to interpret what the data means for individuals, groups and whole classes of students, and then to use it to make decisions about classroom instruction and wellbeing interventions. Data informed practice is the systematic use of a variety of forms and levels of data by educators for this very purpose — improving student learning, classroom practice and overall wellbeing.
The purpose of education is the improvement of student achievement. While we may argue about how this may be measured—and there is no doubt that some aspects of achievement are more easily measured than others—the purpose of education is to change learners; to enable them to do things that they could not previously do.
