Work Package 9 - Practical approaches for validation

Objective: Identify practical approaches for validating major components of probabilistic risk assessments, and evaluate consistency between users in applying guidance on probabilistic approaches

Validation of probabilistic approaches may not be wholly achievable due to the difficulty of confirming probabilistic risk estimates experimentally. However, it should be possible to validate, calibrate or verify many of the underlying models and assumptions. This work package is therefore reviewing practical strategies for validating major components of probabilistic approaches. It will also coordinate work with end-users (Work Package 12) to test whether guidance and tools developed for probabilistic assessments will produce consistent results when used by different assessors or for different pesticides.
