"As a thought leader in early childhood education and care, I have found the SSTEW scale, (part of the suite of resources known as the Curriculum, Leadership and Interaction Quality Rating Scales - CLIQRS) an essential tool to support quality improvement. I have used the scale with individual settings, across a large organisation to improve quality – Goodstart Early Learning, Australia, and also as part of a large English, Department of Education research project – The Study of Early Education and Development (SEED). At all levels the tool gives the teacher or researcher a clear overview of what is required to improve quality for children’s learning in a systematic and evidence-based approach. SSTEW is an uncomplicated resource which improves teacher’s understanding of sustained shared thinking whilst supporting children’s emotional well-being."Sue Robb, OBE, General Manager of Pedagogy and Practice, Goodstart Early Learning, Australia
