Setiap kegiatan belajar harus diketahui sejauhmana proses belajar tersebut telah memberikan nilai tambah bagi kemampuan siswa. Salah satu cara untuk melihat peningkatan kemampuan tersebut adalah dengan melakukan tes. Tes yang berkaitan dengan tujuan ini sering disebut tes prestasi hasil belajar (TPHB).
