1From the highest attainment variable; compared those Not in further education (n = 112, no education after high school) with those currently In further education (n = 229; currently undertaking tertiary-level education).
2From the highest attainment variable; compared those Not in further education (n = 112, no education after high school) with those who have Completed further education (n = 180, completed further education and employed or unemployed).
3Insufficient sample size to conduct analyses. Bolded, significant at the adjusted p < 0.005.
