This section is the main core of the MESH Guide and introduces the idea of schools as learning organisations. Schools as learning organisations (SLOs) is proving a very popular concept in policy and in practice for those schools seeking long term change and improvement (Doherty, 2018; Doherty, 2020; Harris & Jones, 2018; OECD, (2016); Welsh Government, 2017). Creating such schools requires a significant cultural shift, often a change of mind-set and definitely a schoolwide commitment to self-reflection and evaluation.
