Ysgol Yr Eos is located in a Communities First area overlooking the small town of Penygraig in the Rhondda Fawr valley. It was opened in 2004 as a result of the amalgamation of Dinas Junior School and Craig yr Eos Infant School. The school currently has 102 pupils on roll from the ages of three to 11, including eleven full-time nursery children. There are four mixed-age classes. Approximately 39% of pupils are eligible to receive free school meals, which is well above the national average. The school identifies that around 24% of pupils have additional learning needs, which is similar to the national average. No pupils have a statement of special educational needs or use Welsh as a first language. Very few pupils come from an ethnic minority background, speak English as an additional language or are looked after by the local authority. The school was last inspected in January 2008. The current headteacher took up her post in September 2008. The individual school budget per pupil for Ysgol Yr Eos in 2013-2014 means that the budget is £3,912.
