Quality assessments, groundbreaking research and measurement, and user-driven educational solutions
Learn more about ETS Research & Development.
The Foundational Psychometric and Statistical Research Center maintains ETS's legacy as a leading research institution for psychometrics, statistics and technology for educational assessment and learning.
The foundational research carried out by staff in the center has led to groundbreaking developments in:
As the fields of education and educational measurement enter the era of "big data," the center will continue to lead the field by developing measurement models and methods that combine the many possible sources of information about learners' knowledge, skills and abilities.
Sources of data can include typical assessment results, log files and process data. This data captures examinee behavior on a test and information collected over the course of learning activities (e.g., coursework, online learning resources, etc.). The center will continue to be a leader in developing psychometric, statistical and measurement methods using these new sources of information, along with the technology infrastructure to support them.
Staff in the center also help to support research, operational testing and ETS business needs by:
Researchers in the center recently developed a new method for aggregating student growth measures (e.g., at the school level) that borrows strength across years to improve accuracy and cross-year stability, particularly for smaller groups. The methodology was recently approved for operational use by the California State Board of Education.
The Research Technology Group within the center recently developed a web application to collect nearly a half million estimated Leaving Certificate Examination marks from teachers across Ireland, which were needed to produce final accredited grades.
The Institute of Educational Sciences® (IES) recently awarded staff a grant to develop and validate open-source tools that help teachers manage student writing processes. The research team will validate a range of automated measures of student writing and writing processes for classroom management and formative assessment.
Center staff lead the field in developing methods for test security. Examples of this research have:
As leaders in educational measurement, staff have:
