Pupil-teacher Ratio Formula

Equation for calculate pupil-teacher ratio is,

PTR_h^t = E_h^t ÷ T_h^t

where,
E_h^t = Total number of pupils or (students) at level of education h in school year t,
T_h^t = Total number of teachers at level of education h in school year t,
PTR_h^t = Pupil-teacher ratio at level of education h in school year t
