It is expected that their ability to debug system problems will somehow magically develop as they learn how to write code. To an extent, this is a reasonable expectation. Most computer professionals develop debugging skills as a side effect of their programming, but the results vary wildly, running the gamut from little or no debugging ability to bonfire guru status.
