Digital competency in higher education

Every student arrives with full digital competency from secondary school to higher education. Is it a true statement? Teachers and professors in higher education expect that according to the National Curricula, students start to learn ICT - info-communication technology - in primary school and improve them in secondary education. It would be a theoretical situation but the reality is totally different. We can receive homework fulfilled with several grammatical mistakes and misspellings. There are statistical written works with tables, but without diagrams. There are several problems with oral presentations as well. How many slides have to be collected and edited by student for a 15 minutes presentation? The biggest question is whose task to teach student for application ICT on high performance? Has every professor to add any contribution to this development process, or only some of them? Can we expect from student to improve his or her competencies alone? Let's analyze together how to recognize the weakness of students' ICT competences and I try to give some good example for this problem solving.
