Özet

In this study, Item Response Theory (IRT) true-score equating and observed-score equating methods were compared based on preserving test equity property. The data used in this study were 8th grade mathematics test item responses which obtained from booklet 5 and 6 of Trends in International Mathematics and Science Study) (TIMSS) 2011 Turkey sample. Results showed that while IRT true-score equating outperformed IRT observed-score equating in terms preserving first-order equity, however IRT observed-score equating method IRT true-score equating in terms of second order equity property.
