I am lecturing on gender and computer science and have found plenty of material outlining factors that impact female access to computer science courses. I stumbled across this paper: https://dl.acm.org/citation.cfm?id=2920173 which shows significant attainment differences at the highest degree level in UK universities. This raises questions about male focused course material and assessment methodologies. I wondered if there were many other papers on gender and attainment in CS? Google scholar has lots of generic studies, but few focused on CS.
Attainment here could be at any level, including compulsory education and work based assessments
