Student or Learner
Does "keep up to the mark" underlined here means "be a competent IT user"? Thanks!
While these concerns still exist, considerable progress has been made. Few teachers nowadays can afford to be cynics. The widespread adoption of mobile devices by students (and teachers and society at large), driven by affordability, has led many teachers to keep up to the mark.

Because technology is being discussed here, it comes with the in-built meaning that teachers are also having to keep up to date with ever changing IT developments. So, it's an ongoing process.
