Canada
In Canada, the terms "middle school" and "junior high school" are both used, depending on which grades the school caters to. Junior high schools tend to include only grades 7, 8, and sometimes 9 (some older schools with the name 'carved in concrete' still use "Junior High" as part of their name, although grade nine is now missing), whereas middle schools are usually grades 6–8 or only grades 7–8 or 6–7 (i.e. around ages 11–14), varying from area to area and also according to population vs. building capacity.
Another common model is grades 5–8. Alberta, Nova Scotia, Newfoundland, and Prince Edward Island junior high schools typically include grades 7–9, with the first year of high school traditionally being grade 10. In some places students go from elementary school to secondary school, meaning the elementary school covers to the end of grade 8.
In Ontario, the terms "middle school" and "senior public school" (sometimes just grades 7 and 8) are used, with the latter being used particularly in the Old Toronto and Scarborough sections of Toronto plus in Mississauga, Brampton, and Kitchener-Waterloo. In many smaller Ontario cities and in some parts of larger cities,  most elementary schools serve junior kindergarten to grade 8 meaning there are no separate middle schools buildings, while in some cities (such as Hamilton) specific schools do serve the intermediate grades (i.e. grades 6–8 or grades 7–8) but are still called "elementary" or "public" schools with no recognition of the grades they serve in their name.
Quebec uses a grade system that is different from those of the other provinces. In Quebec, there is no middle school section. The secondary level has five grades starting after elementary grade 6. These are called Secondary I to Secondary V.New Zealand
In New Zealand middle schools are known as "intermediate schools." They generally cover years 7 and 8 (formerly known as Forms 1 to 2). Students are generally aged between 10 and 13. There are full primary schools which also contain year 7 and 8 with students continuing to secondary school at year 9 (formerly known as Form 3). Some secondary schools also include years 7 and 8.After 2000 there was an increased interest in middle schooling (for years 7–10) with at least seven schools offering education to this age group opening around the country in Auckland, Cambridge, Hamilton, Christchurch and Upper Hutt.
