Penelitian ini menggunakan metode survei. Populasi pada penelitian ini yaitu siswa KKO kelas X SMA negeri se-DIY yang berjumlah 319 siswa. Sampel sejumlah 132 siswa yang terbagi dalam 8 sekolah penyelenggara kelas KKO se-DIY ditentukan dengan teknik sampel acak proporsional sistematik. Hasil penelitian ini menunjukkan bahwa kemampuan kognitif matematika siswa KKO SMA negeri se-DIY dalam kategori sedang dengan nilai rata-rata 40,62 dari nilai tertinggi ideal 100, task commitment siswa KKO SMA negeri se-DIY dalam kategori sedang dengan nilai rata-rata 95,63 dari nilai tertinggi ideal 150, dan terdapat hubungan yang cukup kuat antara kemampuan kognitif matematika dan task commitment siswa KKO SMA negeri se-DIY. Hal ini dibuktikan dari nilai koefisien kontingensi = 0,328 yang berada pada interval 0,30-0,59 dan nilai signifikansi sebesar 0,05.
