Psychometric Analysis

EdMetric has assembled a team with years of experience in the psychometric field. Our goal is to provide superior psychometric support to state and local district assessment programs, assessment vendors, and education agencies . Psychometrics is the theory or technique of mental measurement. In educational testing, it encompasses the family of methods and mathematical models used to measure student aptitudes and proficiencies. EdMetric values the objective measurement of students’ knowledge, skills, abilities, and educational growth.

Examples of EdMetric’s psychometric services include

  • Reliability analysis

  • Test construction, item, and data analysis using both Classical Test Theory (CTT) and Item Response Theory (IRT)

  • Test form analyses, such as confirmatory factory analyses and unidimensionality analyses

  • Scaling and equating

  • Item calibration

  • Data forensics

Our research scientists’ methodology is firmly grounded in the best practices and professional standards of the APA/AERA/NCME Standards for Educational and Psychological Testing and the NCCA Standards for the Accreditation of Certification Programs. We’ll work with you to determine the best methodologies and analysis tools to meet your psychometric needs.

Assessment Audits

Just like an independent audit of a business is an important step in demonstrating its integrity and sound business practices to its board, shareholders, and regulatory authorities, an independent audit of an assessment is critical to demonstrating its reliability, validity, and overall integrity to its stakeholders and education authorities. EdMetric provides thorough, objective reviews of all components of your assessment program. Our audit process typically includes

  • Technical documentation

  • Test development processes

  • Assessment administration processes

  • Optional onsite visits during test administration

  • Administration support documents

  • Quality assurance processes

  • Test delivery platform (online testing)

  • Scoring mechanisms and processes

  • Sample student data and reports

In addition to reporting our findings and recommendations, we offer assistance in addressing any concerns that are identified during the audit process. We are happy to assist you by auditing your assessment program or helping to clarify how the audit process serves as evidence in your United States Department of Education Peer Review submission. Please contact us to discuss how we can help with your assessment audit project.
