The digital divide between genders and generations in school, i.e., between teachers and secondary school students in Finland, was investigated comparing statistical data in 1999-2000 and in 2002-2004. ICT skills were intertwined with both generation and gender. Teachers were familiar with some traditional applications, students with new applications. Male teachers and students estimated their skills on a higher level than females, but in the second phase, female students' use and competence were close to male teachers'. There was a distinction between low use at school and high use during leisure time. In future, social use of ICT will reduce the differences between users, although the gaps between genders and generations in technical competence will probably remain.
