CARY, NC (Jul. 30, 2012) - Leading certification and licensure testing company, Castle Worldwide, relies on
SAS Analytics in its work with businesses, nonprofit associations and governments. Using SAS® Office Analytics for Midsize Business from the leader in business analytics, Castle applies analytic rigor to help meet the moral and legal burdens of proof and the measurement accuracy required for standardized tests. Testing accuracy and fairness must be indisputable when tests determine who gets or keeps a job and who gets promoted or when public safety is at stake. When Castle engages in testing of medical and nursing specialties, for example, Castle's psychometric work prevents unqualified individuals from performing medical procedures.
"Before SAS, our analytics process was more operationally fragmented," said Andrew C. Dwyer, PhD, Senior Psychometrician at Castle Worldwide. "Pulling data from our databases, cleaning and restructuring it, analyzing it, and creating presentable reports were accomplished using multiple software programs, and it was a source of inefficiency for us. In addition, detailed documentation of our statistical processes, a legal imperative for us, was time consuming - and time is money. Now, SAS documents our workflow so we can more quickly replicate the process. That supports our excellent reputation in psychometrics and test delivery while providing us time and money-saving efficiencies."
Using open-source R was out of the question
Castle uses SAS to collect and analyze test information, improve the measurement fidelity of tests, and demonstrate the validity and reliability of examinations.
"Using open-source software such as R was out of the question - we couldn't guarantee a perfectly repeatable outcome," said Robert Pedigo, Vice President for Client Services at Castle.
