Quality Assurance
The SRC provides individualized attention to investigators during each stage of the research project, from initial data assessment to collection needs, to survey design and interpretation of results.
 
Well-tested and highly developed quality-assurance procedures and controls are in place throughout all stages of the project.
 
Surveys are pre-tested and well-developed coding procedures are followed for open-ended questions.
 
TheCardiff Teleform Information Capture Systemis a major component of the SRC’s quality control process. It eliminates potential errors that could occur with manual data entry.
 
For data entry, 100 percent verification is standard procedure. The SRC conducts verification checks of all data prior to issuing a final project report.
