The Curiosity towards STEM Education Questionnaire Instrument (CQI-STEM) was developed to measure the level of curiosity towards STEM education among primary school students. CQI-STEM consisted of 10 items measuring the two constructs of curiosity towards STEM, namely stretching, and embracing. A total of 166 years five students aged 10 to 11 years enrolled in five urban schools in the Tawau district, Sabah was involved as a research sample. Rasch Measurement Model was applied to determine the validity and reliability of CQI-STEM. The results of the validity analysis found that the polarity of the items through the PTMEA-CORR values showed that all 10 items were > .00 (+). Through item fit analysis, all items were retained because items meet the requirements of the range in MNSQ outfit, ZSTD outfit, and PTMEA-CORR. The value of Raw Variance Explained by Measures was 63.1% (excellent) and the value of Unexplained variance in the first contrast was below 15%, showing that the instrument had strong dimensionality and high construct validity. The CQI-STEM instrument was found to have high reliability with a Cronbach’s alpha value (KR-20) of .93. Results also showed that CQI-STEM has excellent item reliability and moderate-high item separation value of .96 and 4.83 respectively. CQI-STEM also has high person reliability and person separation value of .92 and 3.48 respectively. In conclusion, CQI-STEM has good validity and high reliability in measuring curiosity towards STEM Education among year five students in primary schools.
