Penelitian ini bertujuan untuk 1) mengembangkan instrumen penilaian literasi sains yang terfokus pada tes kemampuan literasi sains, 2) mengukur tingkat kemampuan literasi sains siswa, dan 3) mengetahui respon siswa terhadap produk. Jenis penelitian ini yaitu penelitian dan pengembangan (R&D) dengan desain pengembangan ADDIE. Hasil validasi kelayakan produk berdasarkan penilaian ahli asesmen mendapatkan rata-rata skor validitas 85,44% dan reliabilitas 91,91% , penilaian ahli materi mendapatkan rata-rata skor validitas 84,21% dan reliabilitas 91,91%. Hasil tersebut menunjukkan bahwa produk yang dikembangkan layak digunakan dan diujicobakan. Tingkat kemampuan literasi sains siswa yang terukur berada pada kategori level 3 dengan rata-rata skor aspek kompetensi 48,225 dan aspek pengetahuan 51,215. Rata-rata skor respon positif siswa sangat setuju 58,81%, setuju 27,38%, kurang setuju 9,29%, tidak setuju 2,02% dan sangat tidak setuju 2,50%.
