The function of the health corps was to treat ailments, prevent or halt epidemics, and promote good hygienic conditions.
In eight years, the number of people in rural areas who benefitted from medical service, increased fromone million to almost eight million.

The success of this corps was so great that in 1974 the corps was made responsible for all medical and sanitary services in rural districts.

In 1976 the health corps had 1 422 clinics and employed 1 240 doctors, with 400 laboratories and numerous dispensaries existing throughout the rural areas.

One of the greatest achievements of the health corps was a new confidence of the peasants in "official" medicine.
Before, the rural populance had frequented "healers"; but by 1978 they would go directly to the health corps clinic.
This was an outstanding accomplishment in a country where in earlier days, a doctor often had to give women patients an injection through a curtain under the surveillance of her father or husband.

Like the other two Corps, the Literacy Corps was to supplement the traditional efforts to the government.
It did not replace them.

Before 1963 less than 24% of children between the ages 6 and 12 went to school in the provinces.
The rest remaind illiterate.
In the cities, 74% attended school.
In 1943, on national level, 85,1% of the iranians were illiterate.
The number of pupils in Literacy Corps schools increased byb 692% in 15 years.
During the first 5 years alone, 510 000 boys, 128 000 girls, 250 000 men and 12 000 women attended classes organized in the villages.

The L. Corps also built and repaired schools, mosques and public baths, dredged subterranean canals, planted trees, organized sports clubs, and installed leter boxes to enable regular mail delivery.
By 1978 more than 100 000 had served the L. Corps.

The three Corps were in effect the soldiers of the revolution - versatile, bold and courageous young men and women who never refused a new challenge.
