Gross Intake Ratio Formula

Equation for calculate gross intake ratio is,

GIR^t = [N^t ÷ P^t_a] × 100

where,
N^t = Number of new entrants in the first grade of primary education, in school year t,
P^t_a = Population of official primary school entrance-age a, in school year t,
GIR^t = Gross Intake Ratio in school year t
