The CLA and the adult education survey 

The first version of the CLA released in 2006 was mostly used by countries collecting data for the 

2011 adult education survey (AES). The CLA proved to be very useful and consistent in most cases, 

but there were still additional implementation rules added during the 2011 AES. Further clarification 

was therefore considered useful before the 2016 survey would be conducted (it is due between July 

2016 and March 2017), especially since there was also a new version of the ISCED classification 

released in 2011.  

This manual provides the updates necessary to improve the collection of data on participation in 

learning activities, whether for the AES or any other social survey (such as the LFS and its variables 

related to education and training).
