  • *p<0.05; **p<0.01; ***p<0.001.

  • †All high-education institutes in the study, including non-Athena Charter members, non-recipient of Athena awards, and Bronze and Silver awardees.

  • ‡Intercept coefficient estimates the mean initial percentages of female leaders or professors among the non-recipients (in the model among Athena Charter members) and non-Athena HEIs (in the model among all HEIs).

  • §Duration of being awarded Bronze or Silver during the study period (2012/2013–2016/2017).

  • ¶Intercept variance indicates the between-group variances across HEIs; year invariance indicates the structured variance across years; residual variance indicates the variability of individual HEI’s female representation around the individual regression lines for each subject.

  • AIC, Akaike information criteria; BIC, Bayesian information criteria; HEI, higher education institution.
