In 2000, Association for Educationally Subnormal Children (AESN) was renamed to Association for Persons with Special Needs (APSN). This was accompanied by the official opening of Tanglin Special School.
15 years later, Arthur Road Training Centre was restructured to form Delta Senior School and the Centre for Adults . Both institutions focused on providing vocational training to students with mild intellectual disabilities.
With the move of Katong Special School to La Salle Road, the Vocational Training Centre moved back to Arthur Road and was renamed Arthur Road Training Centre (ARTC), catering to students above 16 years old.
