This study aims to develop a test instrument that can be used to evaluate the concept of chemical equilibrium at the macroscopic, submicroscopic, and symbolic levels of high school students who are declared valid, reliable, have a difficulty index, and have good item discrimination. This study was designed using the Rasch development model, which Wei has modified with ten research stages. The results of the research to test content validity were analyzed through the minifacets program with five validators consisting of four chemistry lecturers at Padang State University and one teacher at high school SMAN 3 Padang, obtaining fit analysis results seen from the exact agreement value of 89.1%, which is very close to the expected agreement value of 89.7%. The test results on 30 students of SMAN 3 Padang who were analyzed through the ministep program showed valid results for all items because they met the criteria for the MNSQ, ZSTD, and Pt Mean Corr outfit scores. The reliability value obtained for the item is 0.74, which meets the sufficient criteria, and Cronbach's alpha reliability value is 0.74, which meets the good criteria. All question items also do not have DIF based on gender. The analyzed index of difficulty and discriminating power fulfilled the good criteria with the classification of easy, medium, and difficult items.

“…Research on the Rasch model has been widely discussed (Chan et al, 2021;Che Lah et al, 2021;Nielsen et al, 2021;Scoulas et al, 2021;Tseng & Wang, 2021). Previous findings show that the Rasch model can be used by teachers and can be applied in final semester exams in various subjects: Chemistry (Purnamasari & Kartowagiran, 2019), Economics (Alfarisa & Purnama, 2019), Morality (Aqidah-Akhlak) (Pratama, 2020), and Physics (Asriadi & Hadi, 2021;Palimbong et al, 2018). Several similar studies were found, such as investigating the quality of test instruments in measuring students' abilities in exams.…”

A high-quality test has a balanced level of difficulty and can be completed by the respondent with their level of abilities. This study analyzed the test instrument used to measure students' mathematics abilities in the semester final exam on System of Linear Equations in Two-Variables. The purposive sampling technique was applied to select the respondent students (N=195). The test items were twenty multiple-choice questions. The researchers performed the data analysis using Rasch model Item Response Theory (IRT) approach with the QUEST program. The analysis revealed that the twenty items’ validity matched the Rasch model with a range of INFIT MNSQ values between 0.89 – 1.17. Items on the final semester exam can be used based on the estimated OUTFIT t-value less than equal to 2.00. The OUTFIT t analysis obtained nineteen qualified items and one unqualified item.

“…Nilai Person Reliability dan nilai Item Reliability yang merupakan hasil uji reliabilitas item soal. Item yang valid atau dapat diterima harus memenuhi setidaknya dua dari tiga kriteria, diperbaiki jika memenuhi salah satunya, dan dibuang ketika tidak ada yang cocok dengan kriteria ini (Palimbong et al, 2019). Kualitas item soal dari aspek reliabilitas item soal menggunakan nilai Cronbach Alpha jika memenuhi kriteria yang ditunjukkan pada Tabel 1.…”

Assessment is a technique for evaluating student learning outcomes and deciding whether or not the learning objectives have been achieved. This study aims to determine the validity, reliability, and difficulty level of the tested items. The data collection technique used a documentation technique in the form of an answer sheet for the odd semester final exam for the 2021/2022 academic year for class XI at SMAS Al-Amjad Medan with a total of 222 respondents, and the form of the question was 45 multiple-choice questions (dichotomies) with five categories of answers. The Rasch model is used to obtain fit items. This analysis was carried out with the help of Winsteps software version 3.7.3. Based on the results of the analysis of the results of the item analysis using the Rasch model, the following conclusions can be drawn: in terms of validity, the questions consist of 86,67% valid and 13,33% invalid; Cronbach's alpha value of 0,95 in the very good category, the Person Reliability value is 0,93, which is included in the excellent category; the Item Reliability value is 0,95 in the special category; the distribution of the difficulty level of the item items is by the rules for making questions because 8 items (17,78%) are in the very difficult category, 9 items are about (20%) are in the difficult category, 23 items are about (51,11%) are in the easy category and 5 items (11,11%) in the very easy category.
