what school do you go to to be a secondary school teacher
Get qualified. To become a Secondary School Teacher, you will need to start Initial Teacher Training (ITT), either through university-led training (e.g. undergraduate or postgraduate award), or through school-led work-based training (i.e. working in a school whilst studying for your PGCE). After ITT, you may gain Qualified Teacher Status (QTS).
Students pursuing a secondary school education degree concurrently major in the area they wish to teach. For example, someone who wants to be a high school science teacher might major in biology or chemistry. Some schools also confer music education or reading education degrees. These specialized degrees usually allow graduates to obtain a license to teach students at all grade levels, including the secondary level.
