Abstract

The invention relates to a pencil for automatic grading, for shading students' answers in tests (aptitude, achievement and competency tests). The pencil comprises an upper click-sleeve with a circular head containing a lead core that is also circular. When the pencil is placed on an answer circle and the top is pressed, the internal lead of the pencil rotates and the answer field is coloured in clearly and precisely without going outside the circle. The pencil is mainly used in automatic grading tests in general.
