What is "secondary technical school"

A secondary technical school was a type of secondary school in the United Kingdom that existed in the mid-20th century under the Tripartite System of education. For various reasons few were ever built, and their main interest is on a theoretical level.

The 1944 Butler Education Act promised a secondary schooling system with three tiers. In addition to grammar schools and secondary moderns, the government intended there to be a series of ‘Secondary Technical Schools’. These would teach mechanical, scientific and engineering skills to serve industry and science.
