This paper focuses on the 'mainstreaming' of charities into schools. There have been growing concerns about the permeation of business and business values in education, but relatively little attention has been paid to the ways in which schools are increasingly engaged in the 'business' of fundraising for charities. Drawing on survey data from the WISERDEducation Multi-Cohort Study (WMCS), the paper outlines young people's relationship with charities. The data show that young people have a high degree of engagement with charities, in which schools play a significant part. There are likely to be many positive aspects to this engagement, inasmuch as it fosters and reflects young people's sense of collective responsibility. However, there are also issues about the extent to which this high level of involvement marginalises other approaches to promote the social good and increases the permeation of business values and business into school. The paper concludes that the current mainstreaming of charities into schools is not necessarily a self-evident 'good' and that this under-researched phenomenon deserves greater critical attention within and outwith schools. Background This paper focuses on the current 'mainstreaming' of charities into schools. Over the last three decades, there has been increasing disquiet expressed about the permeation of business values and business itself into education-particularly in England, the USA, and Australia, but also elsewhere. These have included concerns about the introduction of a culture of entrepreneurialism (Ritchie, 2006; Smyth, 1999; Woods, Woods, & Gunter, 2007), private sponsorship of schools (e.g. Hatcher, 2006), partnership working between schools and business (e.g. Taylor, 1998), commercial activity within schools (e.g. Molnar, 2013; Rayne, 2007), and the implications of new forms of philanthropic investment in education (e.g. Ball, 2016; Olmedo, 2017). However, relatively little attention has been paid to the ways in which schools are increasingly engaged in the 'business' of fundraising for charities. Within the UK, there is a small amount of literature and research on the relationship between charities and schools, but it has tended to be undertaken by charitable organisations.
