The QRT Tool is a professional development tool which helps ECD practitioners grow their own professional understanding of what makes for effective ‘quality’ in early learning programmes. Four dimensions of quality – teaching and learning, the ECD environment, the policy framework, and leadership and management – are linked to sets of self-reflection questions. The Tool includes journal templates for practitioners to record their learning journey. The Mediator Guide linked to the QRT Tool offers guidelines, activities and resources for trainers and others who wish to facilitate the use of the QRT with practitioners.
