Tenby Schools was established in Ipoh in 1960 to cater to the needs of children of expatriate planters, miners and soldiers. The school started as an expatriate kindergarten that became an international school, Ipoh International School (IIS), which later expanded to include a private Malaysian school, Sekolah Tenby.
IIS, the pioneering school of the Tenby Schools group has received a three-year full accreditation by the Western Association of Schools and Colleges (WASC), a testimony of the quality of education it offers. It now joins the ranks of being one of only five schools in Malaysia with such status.
