During the past 30 years or so, a new theoretical basis for educational and psychological testing and measurement has emerged. It has been variously referred to as latent trait theory, item characteristic curve theory, and, more recently, item response theory (IRT). Although this new test theory holds considerable promise as a successor to classical test theory, it has been underutilized by test practitioners. One important reason for this underutilization is that many test developers have not…

Item Response Theory
Item response theory (IRT) seeks to model the way in which latent psychological constructs manifest themselves in terms of observable item responses; this information is useful when developing,…
Item Response Theory: An Introduction to Latent Trait Models to Test and Item Development
TLDR
A comprehensive overview of the IRT and its procedures as applied to test item development and analysis is provided and some suggestions for test developers and test specialists at all levels to adopt IRT for its identified crucial theoretical and empirical gains over CTT are concluded.

Measurement Theory in Language Testing: Past Traditions and Current Trends.
A good test is one that has at least three qualities: reliability, or the precision with which a test measures what it is supposed to measure; validity, i.e., if the test really measures what it is…
Comparison of Validity and Reliability of Two Tests Developed by Classical Test Theory and Item Response Theory
In constructing the test process after preliminary test try outs two tests have been developed by Classical Test and Item Response Theories. The aim of the research is to compare psychometric…
A primer on standardized testing: History, measurement, classical test theory, item response theory, and equating.
TLDR
The history of standardized testing, the frameworks of classical test theory and IRT, and the logic of scaling and equating are presented will aid readers in understanding these concepts of modern testing.
Multidimensional Item Response Theory for Factor Structure Assessment in Educational Psychology Research
This study demonstrates the use of multidimensional item response theory (MIRT) to investigate an instrument’s factor structure. For didactic purposes, MIRT was used to assess the factor structure of…

TLDR
