After being given official recognition by CoNEAU[5] in the 1990s and the signing of a decree by President Eduardo Duhalde in 2002,[6] it became the Universidad Adventista del Plata.

[11] The first Seventh-day Adventist institution in South America was School of the Plata, in the province of Entre Rios, thirteen miles from the city of Diamante, near the Paraná River.

The situation changed on September 26; just when the meetings were about to end, a young man from Uruguay, Luis Ernst, arrived to study at the "Adventist School", an institution that did not yet exist.

The school started out in Las Tunas (Santa Fe) where there was an established Adventist community, until buildings could be constructed in Entre Ríos.

In Las Tunas, the first teacher was Nelson Town; over time the school was moved to land donated by the Lust family.

"[14] The fourth quarter of 1912 focused on Colegio Adventista del Plata in Argentina and the Pua Training-school in Chile.

[15] The close proximity of the Sanatorium of the Plata to the School has benefited the development of the Seventh-Day Adventist Church in South America.

A great share of his time was spent travelling in the horse-drawn carts of the Russian immigrant farmers whose homes were far out in the country in the province of Entre Rios.

[16] Over the years, the sanatorium's fame increased greatly, in part as a result of the efficiency and dedication of missionary doctors Habenicht, Westphal, and Hammerly.

[16] On December 7, 1990, the Colegio Adventista del Plata transformed into the Universidad Adventista del Plata (UAP), being officially recognised by the National Ministry of Culture and Education (Ministerio de Cultura y Educación de la Nación) via Resolution Nº 2241/90.

It was named in honor to Dr. Fernando Chaij, PhD in Philosophy, who wrote several important books leaving a legacy of humble wisdom, Christian message and example to all generations to come.
