This document discusses position classification as defined by Republic Act No. 6758. It outlines the four main categories of positions: professional supervisory, professional non-supervisory, sub-professional supervisory, and sub-professional non-supervisory. Each category is defined based on the level of education, experience, and responsibilities required. Examples are given of position classifications for classroom teachers, administrators, support staff, and career executive positions in the education system and their corresponding salary grades. The classification of teaching positions is noted to be based on the qualifications of the individuals rather than duties, in order to encourage professional growth.
