I recently found this great article written by Terry Norman about Amman Valley School in Ammanford.
The school started in 1914 and this article tell us how it all came about, lists teachers and headmasters and the curriculum of the school back then (sorry girls, you will not like it).
There are a few great photographs of past teachers and headmasters as well. Below is the first paragraph from the article and then a link to the full article.
The story of the struggle to build the first Intermediate (that is, Secondary) school in Ammanford is told in detail in Amman Valley Grammar School – the beginnings in this section of the web site. Briefly, it took almost twenty years for this school to materialise because of objections made by the governors of Llandeilo Intermediate school, built as early as 1896. By that year seven such schools had been built by Carmarthenshire County Council through their 1894 scheme under the Welsh Intermediate Education Act of 1889. These included a reconstituted Grammar School for Boys at Carmarthen, a new Carmarthen Intermediate School for Girls, separate schools for boys and girls at Llanelli, a school for girls at Llandovery, and mixed schools at Llandeilo and Whitland.
