Teacher Practice Improvement Tool: A summary of the underpinning research

In 2025, ACER published the Teacher Practice Improvement Tool (TPIT), as part of its family of improvement tools. A comprehensive review of international research was undertaken to inform the development of the TPIT, which resulted in the inductive development of five inter-related domains that holistically capture the practices of highly effective teachers. This document summarises the research evidence underpinning each of the five domains of the TPIT, drawing on a review of 102 studies. While recognising the interconnections between domains, it presents a structured narrative of key evidence and research-informed considerations for each domain. This summary offers a high-level overview rather than a comprehensive account of all evidence that informed the framework. As such, the references included are illustrative rather than exhaustive.
