Key details

Key details

Simplified Technical English is a simplified style of writing used primarily in the aerospace and defence industries. The language is concise and precise, and the volume of text is typically 20% less than standard text, making it easier to translate and use in different formats. 

Our Simplified Technical English course teaches techniques for producing technical documents that are well-written, clear, concise, consistent and adhere the ASD-STE100 specification.

You will learn how to:

  • Identify the qualities of well-written technical documentation.
  • Develop and write clear, concise, and consistent technical documents.
  • Create clear and directive topic sentences.
  • Focus on creating clear paragraphs that raise the knowledge of your readership to the level required.
  • Employ the core rules of ASD-STE100.
  • Use the ASD-STE controlled dictionary.

Simplified Technical English training is available on-request only, i.e. one-to-one training or a ‘closed’ course for your group. We don’t currently offer scheduled (public) Simplified Technical English courses. This approach means that we can tailor your training to your specific requirements and the type of documentation your organisation produces.

We can host the training at one of our centres, or your venue anywhere in the UK.

Expert trainers

Simplified Technical English courses are hosted by highly experienced instructors, who have held senior technical authoring positions and have 30+ years’ experience in technical authoring and related roles. For further details, see Expert trainers.
