<![CDATA[This study aims to examine the reliability and validity of items and persons using the Rasch model. The students' writing skills were assessed through four constructs elaborated into twenty-four items statements in the form of a rubric. The participants were 40 EFL learners who had taken an essay writing course in TOEFL iBT class whereas the writing samples were taken in collaboration with a language center wherein the TOEFL iBT class was held. The research method employed the Rasch model as a quantitative analysis approach by using three Ministep software outputs used for data analysis: the “statistical summary output” to obtain figures and data in general, item statistics to obtain item validity, and person statistics to acquire person validity. The four assessment constructs: content, structure, diction, and mechanic fulfill item fit measured by OUTPUT MNSQ dan OUTPUT ZSTD though mechanic constructs pass the item fit with a note. The person fit order identified by INFIT MNSQ shows seven students are misfits which need further assessment to find the source of a misfit.]]>
