In computing and interpreting this indicator, one should take into account the existence of part-time teaching, school-shifts, multi-grade classes and other practices that may affect the precision and meaningfulness of pupil-teacher ratios. When feasible, the number of part-time teachers is converted to \u2018full-time equivalent\u2019 teachers; a double-shift teacher is counted twice, etc. Teachers are defined as persons whose
