The IS Rating Scheme
______
What is it?
The IS Rating Scheme (IS) is Australia and New Zealand’s only comprehensive rating system for evaluating sustainability across the planning, design, construction and operational phases of infrastructure programs, projects, networks and assets. IS evaluates the sustainability performance of the quadruple bottom line (Governance, Economic, Environmental and Social) of infrastructure development.
The IS rating scheme aims to:
- Provide a common national language for sustainability in infrastructure.
- Provide a framework for consistent application and evaluation of sustainability in tendering processes.
- Help in scoping whole-of-life sustainability risks for projects and assets, enabling smarter solutions that reduce risks and costs.
- Foster efficiency and waste reduction, reducing costs.
- Foster innovation and continuous improvement in the sustainability outcomes from infrastructure.
- Build an organisation’s credentials and reputation in its approach to sustainability outcomes.
ISv1.2 is the current version of the Rating Scheme. ISv2.0 was released 1 July 2018 and is in beta testing, to participate as a pioneer or pilot, contact us at info@isca.org.au or (02) 9252 9733.
ISCA currently offers four rating phases:

How can the tool be applied?
The tool can be used to secure a rating for a range of infrastructure types, including but not limited to:
- The scheme is applied by a sustainability professional who should be an Infrastructure Sustainability Accredited Professional (ISAP). ISAP status is achieved by completing an IS Training for Professionals | Design and As Built training course, completeing an exam, and paying the ISAP fee.
- This person is a crucial part of the project team to manage the implementation, document collation, and application of the rating and sustainability within a project or asset.
- It is also recommended that in order to increase sustainability capability of the team, that other project members are ISAPs, as well as recommended that mid and senior leadership participate in IS for Project Managers, and IS for Executives workshops.
- The more people within a project delivery team who are on board, the more efficient the process becomes.
- When you register for an IS Rating, you are assigned a Case Manager. A Case Manager works at ISCA, and is an expert on the rating handbook and process, and will guide you to achieving an IS Rating.
The process of undertaking an IS Rating:
There are four stages:
1) Registration – Filling out a registration of interest (ROI) form and signing rating agreement with ISCA.
2) Assessment – The main stage with the most case manager support and interaction. This is undertaken by your designated Case Manager.
3) Verification – This is undertaken by independent third-party verifiers and usually takes 3 months from submission to final score.
4) Certification - Projects will be awarded an IS Rating based on an overall score:
For IS version 1:
- 25-49+ - Commended
- 50-74+ - Excellent
- 75+ - Leading
For IS version 2:
- 20-39 - Bronze
- 40-59 - Silver
- 60-79 - Gold
- 80- 94 – Platinum
- 95+ - Diamond
At this stage, ISCA celebrates with the project team, and organises certification activities and media publications.
