O 2 Chwefror ymlaen, mae ysgolion uwchradd yng Nghymru yn cael eu recriwtio i gymryd rhan yn Rhaglen Ryngwladol Asesu Myfyrwyr (PISA) 2015.   Caiff y broses recriwtio ei chynnal dros sawl wythnos tan ddiwedd Mawrth. Os caiff ysgol ei dewis ar gyfer y rhaglen, byddwn yn ei hannog i gymryd rhan. Caiff ysgolion eu dewis yn gyfrinachol yn seiliedig ar feini prawf a bennwyd gan OECD ar gyfer RM Consulting, sef rheolwr cenedlaethol y rhaglen ar gyfer PISA ar ran Cymru, Lloegr a Gogledd Iwerddon.
As from 2 February, secondary schools in Wales are being recruited to participate in the Programme for International Student Assessment (PISA) 2015.  The recruitment is staged over a number of weeks until the end of March and if a school is selected to participate, I urge the school to take part.  Schools are selected confidentially based on criteria set by the OECD by RM Consulting, who is the national programme manager for PISA on behalf of Wales, England and Northern Ireland.
