Cafodd dros filiwn o bapurau prawf eu hanfon i dros 1,650 o ysgolion eleni a gwnaeth 300,000 o ddysgwyr sefyll y profion hyn yn ystod y cyfnod penodedig ym mis Mai. Roedd gan yr awdurdodau lleol, drwy’r consortia rhanbarthol, swyddogaeth allweddol o safbwynt cefnogi eu hysgolion a monitro’r trefniadau gweinyddol er mwyn sicrhau cysondeb a chwarae teg. Cafodd profion rhesymu rhifiadol eu sefyll am y tro cyntaf eleni felly roedd nifer y papurau eleni yn uwch na’r nifer yn 2013, gan olygu bod y broses gyfan hyd yn oed yn fwy o gamp sylweddol.
This year over a million test papers were sent to over 1,650 schools, enabling 300,000 learners to sit the tests during the test window in May.  Local Authorities, working through the regional consortia, played an important role in supporting their schools and monitoring administration arrangements to ensure consistency and fair play.  Tests on numerical reasoning were sat for the first time this year so the number of papers was even higher than 2013, making the whole process an even more complex logistical operation.
