In this study, it was aimed to examine the interrater reliability of the scoring of paragraph writing skills on foreign
languages with the measurement invariance tests. The study group consists of 267 students studying English at the
Preparatory School at Gazi University. In the study, where students write a paragraph on the same topic, the paragraphs
are rated separately by three different interrater using the same scoring key. The evidence for the validity measurements
was collected with AFA and DFA while the evidence for the reliability measurements was collected by the
Cronbach alpha (α) coefficient. As a result of testing with Multi Group Confirmatory Factor Analysis within the context
of the measurement invariance of the interrater reliability, no evidence of full and partial scalar invariance can be
obtained while evidence of formal configural and metric invariance is obtained. As a result, the lack of evidence of
scalar invariance means that raters scoring the writing skills do not use the same initial level of performance. In this
case, the invariant uniqueness and invariant factor variances could not be tested, and therefore no evidence of reliability
between raters could be obtained.
