D. Campbell Cassidy: An appreciation SISTER Pauline, the formidable headteacher at St Michael’s Academy, in Kilwinning, Ayrshire, was looking for a new Principal Teacher of English. Among the sheaf of CVs on her desk that day in 1973 was one from an applicant whose surname was Cassidy. Spotting his name, Sister Pauline thought he was just the kind of teacher they were after, and appointed him without even an interview. Thus, as Campbell Cassidy’s friends would recall, was a Methodist granted a key job at a Catholic secondary school. Daniel Campbell Cassidy, who has died at the age of 80, was a figure of considerable stature in the fields of English teaching and assessment, and did a great deal of the development for Higher Still, the major reconstruction of education and assessment that took place in the late 1990s.
