IS rating scheme update

2016-03-21 02:08:44

ISCA is planning to release a series of updates to the IS rating scheme through-out 2016. It is intended that there will be phased releases as developments are completed culminating in IS version 2 being finalised for release in early 2017.

Since ISCA launched the IS rating scheme nearly four years ago, industry has successfully completed 14 certified ratings - with more to occur in the coming months. To date 46 projects and assets are registered and applying the rating scheme, totalling over $68 billion in capital value. To ensure continuous improvement, ISCA is always collecting feedback from registered and certified ratings, member working groups and other stakeholders in the industry. The IS rating scheme is ready for an update to incorporate this feedback, broaden the scope to include new themes and to evolve IS Operation ratings from ‘pilot’ to ‘version 1’.

A series of scheme updates will be released throughout the year. The table below describes the key releases and planned dates.
