Penilaian Menengah Rendah (commonly abbreviated as PMR; Malay for Lower Secondary Assessment) was a Malaysian public examination taken by all Form Three students in both government and private schools throughout the country from independence in 1957 to 2013. It was formerly known as Sijil Rendah Pelajaran (SRP; Malay for Lower Certificate of Education). It was set and examined by the Malaysian Examinations Syndicate (Lembaga Peperiksaan Malaysia), an agency under the Ministry of Education.
This standardised examination was held annually during the first or second week of October. The passing grade depended on the average scores obtained by the candidates who sat for the examination.
PMR was abolished in 2014 and has since replaced by school-based Pentaksiran Tingkatan Tiga (PT3).source : https://en.wikipedia.org/wiki/Penilaian_Menengah_Rendah
