What do the levels mean?

Skillswise uses the levels of the National Qualifications Framework, which start at Entry 1, 2 and 3 and then go on to Level 1 and Level 2.

  • Entry 3 covers the basic concepts and is a good preparation for starting a Level 1 course.
  • Level 1 is roughly equivalent to a GCSE D-G grade in England, Northern Ireland and Wales, and a Foundation level at Standard Grade in Scotland.
