England and Wales: The traditional grammar school system in England and Wales ended in the late 1960s and early 1970s as a result of comprehensive education reforms. Most grammar schools were either merged with other schools or converted into comprehensive schools. However, a small number of grammar schools still exist, primarily in selective areas.
Scotland: The Scottish grammar school system was phased out in the 1970s and 1980s, with most grammar schools being merged with secondary schools to form comprehensive schools.
United States: Grammar school typically refers to elementary or primary school in the United States, which usually covers grades K-5. Some grammar schools may extend to grade 6 or 7.
It's worth noting that the term "grammar school" can have different meanings and usage in different countries and contexts. In some cases, it may be used interchangeably with elementary or primary school, while in others, it may refer to selective secondary schools that emphasize classical or traditional education.
