Abstrak. Penelitian ini dilatarbelakangi rendahnya kemampuan Higher Order Thinking Skills (HOTS) siswa Sekolah Menengah Pertama (SMP). Profesionalisme guru sangat erat kaitannya dengan HOTS siswa. Penelitian ini bertujuan untuk menganalisis profesionalisme guru dalam membuat soal HOTS sebelum dan sesudah dilakukan pelatihan. Metode penelitian yang digunakan adalah metode survey. Tujuh belas guru dari 11 SMP se-Kecamatan Padang Utara, Sumatera Barat dijadikan sebagai subjek penelitian. Awalnya guru diminta membuat soal HOTS sebelum diberikan pelatihan. Selanjutnya, para pakar memberikan pelatihan dalam perancangan soal HOTS. Soal HOTS yang disusun oleh guru dianalisis sebelum dan sesudah mengikuti pelatihan. Hasil penelitian menunjukan bahwa 41% guru yang mampu membuat soal HOTS sebelum diberikan pelatihan. Soal HOTS yang dibuat oleh guru masih belum benar, karena kata kerja operasional pada soal masih berada pada level C1-C2. Semua guru dapat membuat soal HOTS setelah diberikan pelatihan. Dari semua guru, 30 % guru mampu memahami sebagian materi pelatihan dan mampu membuat soal HOTS namun masih belum benar dan 70 % guru mampu memahami materi pelatihan dan mampu membuat soal HOTS dengan benar.
Research on teacher professionalism in the learning process experiences exponential growth. One form of teacher professionalism is how teachers can use media that can make learning interesting.

This study aims to analyze the mathematical reasoning abilities of students in the mathematics education study program in the secondary school mathematics curriculum review course. This research was conducted by giving quiz questions in the form of descriptions to a class of students who were then analyzed the answers. The results of the student's answer analysis show that the students' mathematical reasoning ability is still low. The low level of students' mathematical reasoning skills in general lies in the ability of students to analyze problems, make conjectures, determine relationships between variables, and identify links between processes or concepts in a given case. So that many answers from students are not logical and wrong in concluding.
