Examination Development

We partner with your content experts to create test items and assemble test forms, using strict quality-control procedures that have been developed and refined over 60 years of practice.

Item writing. We use proven techniques to help content experts become accomplished item writers, and we have developed stringent item review and validation instruments to ensure that test items are job related and free from bias.


Examination assembly. We use industry-standard methodologies to assemble examination forms that maximize test reliability and validity, and that conform to test specifications.

Standard setting. We are expert in applying a range of standard-setting methods to establish a defensible passing score for your examination.

All of our examination development is supported by an item banking system that can be tailored to your needs, and that can be adapted to allow test development activities to be conducted online.

Scoring and Statistical Services

PES's department of statistics offers a range of scoring and statistical services and is expert in the use of Item Response Theory as well as classical models.
Item analysis and test equating. We analyze raw scores from your examination to evaluate the psychometric quality of test items and forms. We statistically equate parallel test forms to a base form, to ensure the comparability of scores from different forms and the use of a consistent passing score over time.

Scoring and reporting. We score your examination and verify all scores before generating paper-based or online score reports that are customized to your needs and the needs of your stakeholders.

Technology-enabled services. We design and build score-reporting software that is tailored to the requirements of your program. We can provide online score reporting for candidates and other stakeholders, as well as specialized reports that allow you to conduct your own analysis of scores.
