In this paper we investigate the correlation between cheating in school tests and social capital in the context of Italian standardized tests administered by Invalsi. Given that such tests are low-stakes, we find natural to interpret the strong opposition showed by teachers and students (sometimes resulting in explicit boycotting of the tests) as signs of low trust towards the central education authority. Indeed, we find a robust negative correlation between cheating and social capital. We also confirm previous results that have documented that: (i) the presence of an external examiner strongly reduces cheating (Bertoni, Brunello, and Rocco, 2012); and (ii) in less homogeneus classes cheating is more difficult (Bertoni, Brunello, and Rocco, 2012; Lucifora and Tonello, 2012). Furthermore, we show that cheating is instead positively correlated with measures of particularistic social values: such measures (as opposed to universalistic social values) are signs of strong and close links that end up facilitating collusive behaviours.
