What is Psychometrics?

The Science of Human Assessment: studying how we can improve assessment, so that the millions of decisions made every day from test scores can be fairer and stronger.

Assessment Systems has long been recognized as a leader in the field of psychometrics, the science of human assessment. Psychometrics is devoted to the study of the measurement process itself, and how any test or instrument might be improved, not any particular type of knowledge, ability, or trait.

Much of the development of sound, reliable assessments is based on scientific research and sophisticated quantitative analytics, which led to the development of best practices and professional standards, including the APA/AERA/NCME Standards For Educational and Psychological Testing and the NCCA Standards for the Accreditation of Certification Programs.  Our software is designed by and for assessment professionals, to help you implement these best practices and standards!

How can I learn more?

Here’s some resources and tools!

Blog & Resources

The blog contains dozens of articles that discuss current advances in the field, thought-provoking editorials, and introductions to complex concepts.  Additional resources include a list of all assessment conferences and lecture notes for a graduate course in psychometrics.

Psychometric Software

Powerful platforms designed to automate or support the work of PhD psychometricians – as well as free software to help learn complex psychometrics like IRT scoring or Angoff studies.

  • Analytics

    Psychometricians love data.  We were doing “data science” long before the term was cool.  So, what kind of analysis do we do?  Evaluate the performance of items and tests by looking at key statistics as well as fitting complex models like item response theory.  This helps you improve your content, as well as serving as validity documentation.  This, in turn, makes your assessment stronger, more accurate, more effective, and more defensible.

  • Automation, AI, and Machine Learning

    Is your organization still building and delivering its assessment the same way it did 20 years ago?  How about 40 years ago?  Lots of places do so, and that’s a big problem.  Did you know classical test theory is 100 years old and has been essentially obsolete for decades?  We pride ourselves in helping organizations implement modern psychometrics such as item response theory, computerized adaptive testing, and more.  Make your team more efficient, and make your tests smarter, faster, and fairer.
