Andrew Clowes has overseen a major turnaround for the school since returning to Hey with Zion Primary School in 2006. In the bottom seven percent of schools nationally at that time, it has since established itself as one of the top performing schools in the area. In the most recently published national data it was in the top 20% of the country for three years in succession.

The school has also won various awards: U.C.L. "Excellence in Literacy" (2018), S.I.L. Reading Quality Mark (2022);  Geography Association quality mark (2018 and 2021), Historical Association (gold) award (2015, 2016 and 2020), Primary Science quality mark (2016 and 2020), Global Neighbours and Inclusive School awards (2020). It also featured in the 2019 Education Parliamentary Review as a "best practice" representative.  Its latest church school inspection judgement (SIAMS, 2019) was "excellent”; it’s latest Ofsted judgement (2022) “good”.

Beyond the curriculum, Hey with Zion Primary School prides itself on providing a wide range of extracurricular activities to fulfil its vision of educating its children to do the best they can for themselves and others and to live life to the full. 

In July 2020, Andrew Clowes appeared on a Leaders Council of Great Britain and Northern Ireland podcast, discussing the school's response to the Covid-19 pandemic, the importance of leadership and the role that it has played in his career to date. 

He has  written various articles on education for the Leaders Council, and these are accessible below.
