Technical schools are focused on the STEM programs. These programs are traditionally Science, Technology, Engineering, and Math. Many of the examples below are research driven. What makes them different from a trade school is there are other programs offered that follow the more traditional 4 year college curriculum. 

A trade school (also known as a technical school) is a postsecondary educational institution designed to train students for a specific job in a skilled trade career. Most importantly, a trade school offers hands-on training to prepare students for actual work in their chosen field. Trade school programs are concentrated entirely on relevant job training, which is different from  2-year or 4-year colleges that typically require general education courses, such as English or Biology.

For example, if you’re interested in becoming a welder but you’ve never welded before, where can you learn how to weld? A welding trade school provides an environment where you can practice in a setting that prepares you for the job. Most trade schools are 1 - 2 year programs.
