Evaluative criteria define a “high quality” or “successful” evaluand and provide the basis for judgment of merit and worth, yet they are often assumed and implicit in the evaluation process. This article presents an empirically supported model that describes and integrates two aspects of criteria: domain and source. Domain identifies the focus or substance of a criterion, while source describes the individual, group, or document from which it is drawn. Developed from a synthesis of evaluation literature and empirical analysis of evaluation reports, the model defines 11 criteria domains and 10 sources and reveals the relationships among them. In this integrated model, the two dimensions can be used together as a thinking tool to guide evaluators in specifying criteria, in empirical research on the valuing process, and as a conceptual framework and language for theorists prescribing criteria selection.

评估标准定义了“高质量”或“成功”评估，并为判断优劣提供了基础，但在评估过程中它们经常被假定和隐含。本文提供了一个经验支持的模型，该模型描述和集成了标准的两个方面：域和源。域标识准则的重点或实质，而来源则描述从中抽取准则的个人，团体或文档。该模型由评估文献和评估报告的经验分析综合而成，定义了11个标准域和10个来源，并揭示了它们之间的关系。在此集成模型中，可以将这两个维度一起用作思维工具，以指导评估人员指定标准，进行有关评估过程的实证研究，
