An inexpensive retrospective standard setting method based on item facilities

Criterion Item Standard Setting

A method for establishing a minimum passing standard for a multiple choice test is described. The procedure is based on expert judgment about the content of test items. The method can also be used to monitor or adjust a standard that is already in place. The procedure carries advantages that are not available from other approaches to standard setting. It is easy to implement and easy for partic...

An Appropriate Theoretical Model for Developing Ambient Air Quality Standard in Iran Based on Standard Setting Approaches of Different Parts of the World

Background & objectives: Environmental standards are quantitative criteria for protecting the environment from pollution and degradation. One of the solutions to improve air quality status is to use reasonable limits to prevent excessive release of airborne contaminants from their various sources. On the other hand, these standards are effective in evaluating air pollution reduction strategies....
