The Uganda school system offers seven years of primary education (P1 to P7), followed by an examination (the Primary Leaving Examination), consisting of three papers, English, Mathematics, and General. About 47% of the primary school age population are in government-aided schools, and a further 20 to 25% are in private ones, many of which are unlicensed and of dubious quality. In 1978, the intake of students into the first year of government-aided private schooling totalled 58% of the estimated eligible population.
