Development of an evidence rating scale for the New Zealand social sector
Standards of evidence are rating scales against which evidence for the effectiveness of social interventions can be assessed. International best practice in the development and use of standards of evidence was reviewed, and follow-up work with Superu developed an evidence rating scale for New Zealand. The rating scale has been adopted for use in assessing the evidence supporting social investment budget bids in 2018.
Two publications were produced.
- In Focus: Standards of evidence for understanding what works: International experiences and prospects for Aotearoa New Zealand describes international and New Zealand standards of evidence, and recommends the features that a New Zealand standard of evidence should have.
- An Evidence Rating Scale for New Zealand: Understanding the effectiveness of interventions in the social sector provides a standard against which the evidence for effectiveness of social sector policies, programmes, services or practices can be assessed. It guides the grading of social interventions by their strength of evidence for effectiveness, and their suitability for scale-up or implementation in new locations. It uses best practice, encompasses a broad range of evidence types, and accommodates a New Zealand perspective.
