Introduction

Criteria for Reporting and Evaluating Exposure Datasets (CREED) is a framework for evaluating the relevance and reliability of a reference object for a given exposure assessment question across a series of questions. Users set criteria for it to be relevant to their question, and use a pre-defined set of reliability criteria.

The criterion scores assigned for each criterion during the CREED assessment are used to calculate an overall useability score for both Relevance and Reliability at the gold and silver level. Silver scores are calculated based on the highest (worst) score for all required questions, and gold for all recommended questions. Data source usability scores are, from high to low:

Usability Scores

Gold - Relevant/reliable without restriction

Gold - Relevant/reliable with restriction

Silver - Relevant/reliable with restriction

Silver - Relevant/reliable without restriction

Gold or Silver - Not usable

This table is automatically filled out by the eData app during the CREED assessment process.
