He has topped the world chess rankings in U-8, U-10, U-11 and U-12 categories by a wide margin. In April 2023 he became the youngest ever FIDE Master.

In September 2023, at the age of nine, Oro became the youngest ever to earn an international Master rating after finishing runner-up in the ITT Copa Ciudad de Comodoro Rivadavia tournament.

On 30 June 2024, Faustino Oro achieved his third IM norm and 2400 FIDE Elo points, becoming the youngest International Master in history at the age of 10 years, 8 months and 16 days, beating the record previously held by Abhimanyu Mishra.
