ESCO v1 is the first full-scale ESCO version. Was released in mid 2017.

Different from the previous ESCO versions which have versioning numbers starting with 0 (zero), it is not only recommended for piloting and testing, but also for systems in production that deliver services to end users. As of this version, a versioning mechanism will keep track of changes in ESCO.

Development of ESCO v1

Between ESCO v0 and ESCO v1, the content of the classification was entirely re-developed. The work took from 2011 until 2017. The ESCO Maintenance Committee oversaw the revision process.

A Cross-sector Reference Group supported the horizontal development of the classification throughout the whole process.
