The survey of grammar teaching in foreign language (FL) teaching starts in 1920 with some important government reports on the teaching of language, and ends in 2016 with another report on pedagogy in FL teaching. In between these points, we find two significant dates: 1951, when O-level and A-level were introduced as the official school-leaving qualification for 16-year olds; and 1988, when O-level and CSE were merged into the present GCSE exam. Grammar instruction was important in the 1920s, contested in the 1950s, almost dead in the 1980s, and reviving in the 2010s. These changes are linked to English teaching, undergraduate FL syllabuses, and the target population for FL teaching.
