In the UK education system, an 'audit culture' has led to pressures being placed on students to achieve high grades in their GCSEs. It has been suggested that schools are required to achieve good academic results and look after their students' wellbeing, causing a conflict in relation to public examinations, such as GCSEs. School staff support both performance and wellbeing by preparing students for exams. However, research suggests that there is a danger that many underperform, or are negatively affected (emotionally) by exam stress, or both. This paper describes a research project within the UK. The aims of which were to explore the views of students who had recently taken GCSE exams, to gain an understanding of how they felt their GCSE experiences affected their wellbeing and performance, to find out what factors contributed to or alleviated their levels of exam stress, and whether theories relating to exam stress such as Achievement Goal Theory could be used to explain the individual differences in levels of exam stress. Findings and conclusions provided ways to improve the support for students during their GCSEs, improving academic performance and wellbeing.
