Bronwen was instrumental in developing the STA’s formal qualification in technical analysis, and apart from teaching courses for the STA Diploma, in the early years she wrote and marked all the papers. She was a Board member from 1986 until 1993, when she went to work at Adia in Abu Dhabi, and was also a long-standing member of the board of IFTA and of its executive committee. Through this connection, she was widely respected throughout the world, as well as in the UK, as an outstanding technical analyst and an expert in the teaching of technical analysis.
Bronwen died on 30 December 1992, aged only 60. In her memory, the Board of the STA voted to create an annual award for the best Diploma paper, which is known as the Bronwen Wood Memorial Prize.
