Diktantni o’tkazishdan 1 kun oldin o’quvchilarni ogohlantirish kerak. O’quvchilarning yonida barcha o’quv qurollari shu jumladan chizmachilik asboblari bo’lishi zarur. Olingan bilimlarning mustahkamlashning va tekshirishning yana bir usuli testdir. Geometrik testlar – bu masalalar to’plami emas, balki maxsus vazifalar to’plami bo’lib, ular shunday tuzilganki o’quvchi maktab dasturidan nimani va qay darajada egallaganini tekshiruvchi omildir.
