The aim of this study was to examine the relationship between non-cognitive constructs grit, emotional intelligence and mindset, and academic achievement. A mixed method design was employed comprising quantitative and qualitative data. Participation was voluntary and obtained from a convenience sample. The design was correlational with responses collected via an online survey. Measures included the 12-item Grit Scale, Schutte Emotional Intelligence Scale and the Theories of Intelligence Scale. The survey also contained qualitative questions to gain deeper participant insight. Statistical tests did not show significant support for the main hypothesis, however additional analysis and qualitative data evidenced support for the previous research. Findings included significant relationship with non-Irish participants, acknowledgement of grit, emotional intelligence and mindset as contributing factors to achievement, and gender differences in emotional intelligence. The main conclusion drawn is that IQ is not the sole determinant of success and additional research is required to further evidence.
