A unit is defined by a set of knowledge, skills and competence needed to carry out an earth building activity, and a list of criteria and indicators for asssement.

• Knowledge is factual and theoretical, described by a list of topics.

• Skills are cognitive and practical, and are described by a list of actions.

• Competence describes the responsibility, autonomy of a person and its ability to supervise others in a given situation.

• The criteria are designed to assess the skills of each ECVET unit.
• An additional transverse list of criteria applies to method of work, common to all of the units.
  

• Level 1 is an introductory level for people to discover earth building. They can only work under direct supervision.
  
• Level 2 does not mean less quality, but more time and instructions. They can work under supervision with some autonomy
  
• Levels 3 and 4 correspond to autonomous professional work. The difference between level 3 and 4 lies in the organisation and supervision: a level 3 is a person working autonomously but not supervising other workers and not dealing with the whole organisational process of the building site.
