Question: What comprehensive school was established where Rhostrehwfa can be found?

full_context: Document 1: Comprehensive school: Comprehensive schools are primarily about providing an entitlement curriculum to all children, without selection whether due to financial considerations or attainment. A consequence of that is a wider ranging curriculum, including practical subjects such as design and technology and vocational learning, which were less common or non-existent in grammar schools. Providing post-16 education cost-effectively becomes more challenging for smaller comprehensive schools, because of the number of courses needed to cover a broader curriculum with comparatively fewer students. This is why schools have tended to get larger and also why many local authorities have organised secondary education into 11–16 schools, with the post-16 provision provided by Sixth Form colleges and Further Education Colleges. Comprehensive schools do not select their intake on the basis of academic achievement or aptitude, but there are demographic reasons why the attainment profiles of different schools vary considerably. In addition, government initiatives such as the City Technology Colleges and Specialist schools programmes have made the comprehensive ideal less certain.

Document 3: St Anthony Head: St Anthony Head is a National Trust property situated at the southernmost tip of the Roseland Peninsula, Cornwall, England, United Kingdom, overlooking the entrance to one of the world's largest natural harbours: Carrick Roads and the estuary of River Fal. It preserves the former St Anthony Battery, built in 1895-97 to defend the estuary of the River Fal.
Document 4: Comprehensive school: In these schools children could be selected on the basis of curriculum aptitude related to the school's specialism even though the schools do take quotas from each quartile of the attainment range to ensure they were not selective by attainment. A problem with this is whether the quotas should be taken from a normal distribution or from the specific distribution of attainment in the immediate catchment area. In the selective school system, which survives in several parts of the United Kingdom, admission is dependent on selection criteria, most commonly a cognitive test or tests. Although comprehensive schools were introduced to England and Wales in 1965, there are 164 selective grammar schools that are still in operation.[citation needed] (though this is a small number compared to approximately 3500 state secondary schools in England). Most comprehensives are secondary schools for children between the ages of 11 to 16, but in a few areas there are comprehensive middle schools, and in some places the secondary level is divided into two, for students aged 11 to 14 and those aged 14 to 18, roughly corresponding to the US middle school (or junior high school) and high school, respectively. With the advent of key stages in the National Curriculum some local authorities reverted from the Middle School system to 11–16 and 11–18 schools so that the transition between schools corresponds to the end of one key stage and the start of another.
Document 5: Comprehensive school: In Ireland comprehensive schools were an earlier model of state schools, introduced in the late 1960s and largely replaced by the secular community model of the 1970s. The comprehensive model generally incorporated older schools that were under Roman Catholic or Protestant ownership, and the various denominations still manage the school as patrons or trustees. The state owns the school property, which is vested in the trustees in perpetuity. The model was adopted to make state schools more acceptable to a largely conservative society of the time.
Document 6: Comprehensive school: The first comprehensives were set up after the Second World War. In 1946, for example, Walworth School was one of five 'experimental' comprehensive schools set up by the London County Council Another early comprehensive school was Holyhead County School in Anglesey in 1949. Other early examples of comprehensive schools included Woodlands Boys School in Coventry (opened in 1954) and Tividale Comprehensive School in Tipton.
Document 7: Raising of school leaving age in England and Wales: In 1944, Rab Butler introduced the Education Act 1944 which amongst other changes, including the introduction of the Tripartite System, included raising the school leaving age to 15. Although the act should have been brought into effect as from September 1939, it was not implemented because of the effects of World War II, but was eventually enforced from April 1947. The comprehensive school system has since replaced the Tripartite System brought in by this act across most of England. This act also recommended compulsory part - time education for all children until the age of 18, but was dropped, in similar fashion to the 1918 Act, to cut spending after World War II.

Document 10: Comprehensive school: The largest expansion of comprehensive schools in 1965 resulted from a policy decision taken in 1965 by Anthony Crosland, Secretary of State for Education in the 1964–1970 Labour government. The policy decision was implemented by Circular 10/65, an instruction to local education authorities to plan for conversion. Students sat the 11+ examination in their last year of primary education and were sent to one of a secondary modern, secondary technical or grammar school depending on their perceived ability. Secondary technical schools were never widely implemented and for 20 years there was a virtual bipartite system which saw fierce competition for the available grammar school places, which varied between 15% and 25% of total secondary places, depending on location.[citation needed]

Document 13: Comprehensive school: In 1970 Margaret Thatcher became Secretary of State for Education of the new Conservative government. She ended the compulsion on local authorities to convert, however, many local authorities were so far down the path that it would have been prohibitively expensive to attempt to reverse the process, and more comprehensive schools were established under Mrs Thatcher than any other education secretary.
