What is CLEA?
For the time being, CLEA has three versions:
- CLEA250 (basic level) targets concept-to-word mapping and is required for creating entries in UNL-NL dictionaries;
- CLEA450 (intermediate level) targets word description and is required for creating entries in NL dictionaries; and
- CLEA700 (advanced level) targets grammar description and is required for creating rules in NL grammars.
Former holders of CLEA450 have been automatically granted CLEA250, which is a lighter version of CLEA450.

It has been originally proposed by the Institute of Advanced Studies of the United Nations University, in Tokyo, and has been currently promoted by the UNDL Foundation, in Geneva, Switzerland, under a mandate of the United Nations.
