Most projects and research pursuits rely on the scientific foundation of measurement and evaluation. Psychometric evaluation is a multi-step process; it entails testing one's measuring device to assure it meets the rigors of the scientific process (and the criteria of the end user). Services in this domain include:

• Assessment of reliability (e.g., inter-rater, internal consistency, etc.)
• Testing the validity evidence (e.g., content, construct, criterion, etc.) to assure the instrument is measuring what it is purporting to measure
• Exploratory and confirmatory factor analysis
• Item analysis to assess quality (and discriminability) of items
