Various professions demand numeracy skills of at least level 3, including the teaching profession, but teacher numeracy ability data is currently not available. Numeracy is the ability to apply mathematical concepts to make decisions. This research aims to assess the numeracy ability of elementary school teachers based on gender and teacher education level. The school can use data on teacher numeracy skills to evaluate the implementation of numeracy literacy programs in schools. In this study, use a descriptive approach. A total of 27 primary school teachers were the subject of the study. Data collection used general and advanced numeracy test instruments, with 10 questions divided into 3 general numeracy questions and 7 advanced numeracy questions. The collected data was analyzed using descriptive statistical techniques by calculating frequency, average, and data trends. The study results were then presented in the form of a histogram and narrated. The result of this study was the numeracy ability of elementary school teachers classified as moderate. Female teachers have better numeracy skills than men. Teachers with S2 education levels have better numeracy skills than those with S1 education levels.  Teacher numeracy skills need to be improved, especially in male teachers who have lower than female teachers. Professional development of teachers in the field of teacher numeracy literacy needs to be improved, and the development of numeracy literacy tests was required in order to measure teacher numeracy skills.

Pada abad 21, kemampuan numerasi sangat penting untuk dikuasai semua kalangan masyarakat. Kemampuan numerasi masyarakat tidak lepas dari kemampuan numerasi guru sebagai tenaga pendidik. Pengetahuan numerasi guru perlu diketahui, sebagai upaya memaksimalkan peran guru dalam pembelajaran numerasi. Alat ukur yang dapat digunakan adalah instrumen tes. Penelitian ini bertujuan untuk mengembangkan instrumen Tes Numerasi Guru (TUGU). Penelitian ini menggunakan model pengembangan 4D. Jenis data dalam penelitian ini adalah data kuantitatif. Data dikumpulkan melalui angket, rating scale, dan tes. Hasil penelitian ini adalah instrumen TUGU untuk mengukur kemampuan numerasi guru SD. Instrumen TUGU dinyatakan layak sebagai instrumen tes karena sudah melalui pengujian konten dan uji empiris. Hasil uji validitas isi menunjukkan indeks Aiken melebihi 0,8, termasuk kategori tinggi. Respon guru menunjukkan skor 4,58, termasuk kategori sangat baik. Uji validitas menunjukkan rata-rata 0,536, termasuk kategori valid. Uji reliabilitas menunjukkan koefisien 0,70, sehingga instrumen dinyatakan reliabel. Uji daya beda menunjukkan skor rata-rata 0,438, yang termasuk kategori sangat baik. Uji tingkat kesukaran menunjukkan skor rata-rata 0,596, termasuk kategori sedang.
