Abstract The purpose of this study was to find out how the level of difficulty on the Middle Semester Assessment of Mathematics class VII SMP Negeri 5 Cibitung for the 2021 2022 academic year was based on Bloom's taxonomy. This research was conducted at SMP Negeri 5 Cibitung. The type of research is descriptive research with a quantitative approach. The data collection technique used is the documentation method, while the data analysis technique uses Microsoft Excel with formulas to test validity, reliability, difficulty level, discriminatory power, and calculate the percentage level of difficulty of questions based on Bloom's taxonomy. Based on the results of the analysis, it can be concluded that there are 18 items (90 percent) which are declared valid, and the items are declared reliable with a reliability coefficient of 0.83. The results of the analysis of questions based on Bloom's taxonomy, obtained questions belonging to the ability to understand (C2) as many as 5 items (25 percent), belonging to the ability to apply (C3) as many as 10 items (50 percent), and belonging to the ability to analyze (C4) as many as 5 items (25 percent). There are no questions belonging to the ability to remember (C1), evaluate (C5), and create (C6), then the questions are classified based on the students' thinking criteria, and the questions that are classified as Higher Order Thinking Skills (HOTS) are 5 items (25 percent) and questions that are classified as Medium Order Thinking Skills (MOTS) as many as 15 items (75 percent).Keywords difficulty level, mid-semester assessment, Bloom's taxonomy.Abstrak Tujuan penelitian ini untuk mengetahui bagaimana tingkat kesulitan pada soal Penilaian Tengah Semester pelajaran matematika kelas VII SMP Negeri 5 Cibitung tahun ajaran 2021/2022 berdasarkan taksonomi Bloom. Penelitian ini dilakukan di SMP Negeri 5 Cibitung. Jenis penelitian yaitu penelitian deskriptif dengan pendekatan kuantitatif. Teknik pengumpulan data yang digunakan adalah metode dokumentasi, sedangkan teknik analisis data menggunakan Microsoft Excel dengan rumus-rumus untuk uji validitas, reliabilitas, kemudian menganalisis soal PTS buatan guru dengan mengelompokkan kategori soal berdasarkan taksonomi Bloom dan menghitung persentasenya, serta menilai soal PTS buatan guru berdasarkan kriteria LOTS, MODS, dan HOTS. Berdasarkan hasil analisis, maka dapat disimpulkan bahwa terdapat 18 butir soal (90 persen) yang dinyatakan valid, dan butir soal tersebut dinyatakan reliabel dengan koefisien reliabilitas 0,83. Hasil analisis soal berdasarkan taksonomi Bloom, diperoleh soal yang tergolong kemampuan memahami (C2) sebanyak 5 butir soal (25 percent), yang tergolong kemampuan mengaplikasikan (C3) sebanyak 10 butir soal (50 percent), dan yang tergolong kemampuan menganalisis (C4) sebanyak 5 butir soal (25 percent). Tidak terdapat soal yang tergolong kemampuan mengingat (C1), mengevaluasi (C5), dan mencipta (C6), kemudian soal digolongkan berdasarkan kriteria berpikir peserta didik, dan diperoleh soal yang tergolong Higher Order Thinking Skills (HOTS) sebanyak 5 butir soal (25 persen) dan soal yang tergolong Medium Order Thinking Skills (MOTS) sebanyak 15 butir soal (75 persen). Kata kunci: tingkat kesulitan, penilaian tengah semester, taksonomi Bloom.DOI http://dx.doi.org/10.23960/jpmipa/v23i2.pp633-641
