Impact Assessment Special Interest Section

The Impact Assessment Special Interest Section (SIS-IA) was set up to achieve good environmental outcomes by:

  • Promoting ethical and competent practice of impact assessment by environmental practitioners through developing tools, competencies and a certification process
  • Developing and promoting, within the wider community, practices to support and extend impact assessment through institutional and decision-making frameworks, processes, standards, competencies and tools.


Membership of the SIS-IA is open to members of:

  • Environment Institute of Australia and New Zealand
  • New Zealand Association for Impact Assessment

Certification of Impact Assessment Specialists

The SIS-IA worked with the Certified Environmental Practitioner (CEnvP) program to develop certification criteria for Impact Assessment Specialists. In addition to extensive relevant experience and suitable qualifications, a CEnvP Impact Assessment Specialist must demonstrate an excellent understanding of impact assessment methods, high level analytical capabilities and strong interpersonal skills in working with proponents, regulators and stakeholders.

Memorandums of Understanding developed with other associations

The SIS-IA negotiated memorandums of understanding (MoUs) with the New Zealand Association for Impact Assessment and the International Association for Impact Assessment. These MoUs ensure EIANZ works with these associations to:

  • Promote and enhance the quality of impact assessment
  • Promote academic exchange and professional training
  • Encourage participation in each others’ conferences and activities
  • Exchange the latest information in environmental assessment.

IA workshops held

The SIS-IA has run workshops at EIANZ conferences on topics such as scoping of impact assessments, public participation and development of early career professionals. Further workshops are planned.

Resources developed for IA practitioners

The SIS-IA has developed resources to support effective implementation of IA. The documents have been prepared by experienced IA practitioners within the SIS-IA to provide guidance on good practice in IA. While they have been written to apply generally in Australia and New Zealand, IA practitioners should also consider the specific requirements of the jurisdiction within which they operate.

These IA resources are available under the 'Resources' section of the website →
