EASI: Building on Ayres’ legacy with a global, co-produced vision

The Evaluation in Ayres Sensory Integration (EASI) stands on the strong scientific foundations of Dr A. Jean Ayres. Its development is led by Dr Zoe Mailloux, who served as Dr Ayres’ research assistant on the Sensory Integration and Praxis Tests (SIPT), first published in 1989. Like the EASI, the SIPT itself was built on an earlier suite of tools, the Southern California Sensory Integration Tests (SCSIT), Ayres’ original test battery for identifying sensory integration difficulties.

What makes the EASI especially exciting is its scope and inclusivity. A worldwide normative data project ensures that the test reflects the diversity of the people we serve. As part of this global effort, an EASI UK and Ireland team is coordinating local contributions so that our regional data is well represented and ethically gathered.

Progress to date in the UK and Ireland includes:

• Reviewing draft items under development and providing structured feedback to the international team.
• Creating active social spaces to connect therapists trained in, or learning, Ayres Sensory Integration across the UK and Ireland via the ASI Wise & Sensory Project’s peer support groups – vibrant communities of practice.
• Designing our UK and Ireland contribution to help train testers to ICE -ASI international standards so that high-quality, reliable normative data collection can take place.

The energy around Ayres Sensory Integration research and development is palpable. With the EASI advancing through rigorous, collaborative stages, we are moving towards a contemporary assessment that honours Ayres’ original insights while meeting today’s validity, reliability, and cultural relevance standards.

If you are an OT, PT, or SLT with ASI training or in training and would like to support UK and Ireland activities, we would love to hear from you. Together, we can keep this work grounded in fidelity, co-production, and meaningful outcomes for the people we support.
