The latest version of Simplified Technical English (STE), Issue 9 of ASD-STE100, arrived on January 15, 2025. This update, three years in the making, signifies more than just a revision; it marks STE’s transition from a specification to a full-fledged international standard.

Developed by the ASD Simplified Technical English Maintenance Group (STEMG) with input from national and multi-country Support Teams (STEST), Issue 9 reflects a commitment to clarity, safety, and alignment with international standards. The STEMG, comprised of industry experts and linguists, meticulously reviewed 160 items and change forms, including 11 specifically related to meta-terminology. This collaborative process ensures the standard meets the needs of technical writers and, ultimately, the end-users of the documentation.

From Specification to Standard: A Key Shift

This isn’t just a name change. The move to “standard” reflects STE’s broader applicability. While a specification governs individual projects, a standard establishes universal rules. The official document title now reflects its registered trademark: “ASD-STE100 Simplified Technical English: Standard for Technical Documentation.”

Originally designed for aerospace and defense, STE is now used across various sectors, including rail, medical, automotive, and renewable energy. Its focus on clear, unambiguous language reduces human error, especially for non-native English speakers, leading to improved documentation quality, enhanced safety, and smoother global communication.

The Core of STE: Rules and Dictionary

ASD-STE100 is built on two pillars: writing rules and a controlled dictionary. The rules provide strict guidelines for grammar, style, and sentence structure, making content easily understandable for a global audience. The dictionary lists approved words, their definitions, and usage examples, along with a list of unapproved words and alternatives. This standardization of terminology ensures consistency and avoids confusion.

What’s New in Issue 9?

While no new rules were added, 31 of the 53 existing rules were clarified. The dictionary saw significant updates, with 555 entries revised for accuracy and relevance. A major focus was the meta-terminology review. In the context of ASD-STE100, terminology refers to the words and phrases used within the standard itself, such as “technical noun” and “technical verb.” Meta-terminology, on the other hand, refers to the terms used to describe and categorize those terms, such as “noun” and “verb.”

Essentially, meta-terminology is the language we use to talk about the language of the standard. It provides a framework for understanding the relationships between different types of terms and how they should be used.

The distinction between terminology and meta-terminology is important because it helps to ensure that the standard is clear, consistent, and easy to understand. By using precise meta-terminology, the ASD-STE100 Maintenance Group can avoid ambiguity and ensure that the standard is interpreted correctly by technical authors and translators.

Meta-Terminology Refresh: Aligning with International Standards

Issue 9 aligns with ISO 1087-1:2019, modernizing legacy classifications. “Technical name” and “technical verb” are now “technical noun” and “technical verb (term).” Subject field classifications have also been refined, with new categories added under Rules 1.5 and 1.12.

User-Centric Approach: Balancing Precision and Practicality

The STEMG prioritized usability for technical writers, recognizing that most aren’t linguists. Simplicity was key, even while maintaining terminological precision. For example, the dictionary retains the “word” column designation instead of more complex lexicographic terminology. Balancing correct meta-terminology with practical application was a key challenge. The goal was always to empower authors to create clear, accessible documentation. Defining technical verbs, in particular, required careful consideration to ensure both accuracy and ease of understanding.

The Future: AI and Collaboration

The STEMG and STEST are now exploring how AI can enhance STE compliance checks, provide real-time feedback, and automate terminology updates. Collaborations with universities are examining AI-driven tools to streamline technical documentation, improve accessibility, and ensure interoperability.

Issue 9 represents a significant step for ASD-STE100. Its evolution to a global standard, coupled with meta-terminology updates and alignment with international standards, ensures its continued relevance. With a focus on AI and digital transformation, STE is poised to evolve further in the age of smart documentation and Natural Language Processing.

I’ve found all the rules introduced in this workshop equally valuable and applicable in my field of work. The ASD-STE100 Specification is very useful for searching examples and finding STE compliant alternatives. It was also great that we has such a large number of practical exercises. Personally, it would be more valuable to have more context available. This helps us judge how to apply STE optimally. Thank you Shumin! Your workshop was concise, clear, and pragmatic. I also liked the occasional humour! Diane Goodrick, Information Architect/ Author Trainer, Schindler Group.

Summary

Simplified Technical English (STE) is a controlled language that is used to write technical manuals in such a way that they can be more easily understood by an international audience. STE helps to make translations cheaper and more accurate. Often a formal requirement for aircraft and defence maintenance documentation, STE can easily be adapted to all technical industries and beyond. Ms. Shumin Chen will teach participants how to correctly and effectively use STE in practice. She will also address some of the mistakes commonly found in technical writing and the frequently incorrect use of common STE writing rules.

I will definitely recommend this training to writers of many fields, especially technical fields. The material, presentation, and instructor are fantastic. I learned a lot about ASD-STE. Even though I’ve been using this writing convention for almost eight years, formal training brought much clarity and comprehension that I had not previously realized. I now know that an aptitude for writing and a copy of the STE rules is a good start, but not enough. This course takes your understanding to a professional level. Lauren Gelli, Senior Technical Writer, Aerotech Inc.

Trainer’s qualifications

Ms. Shumin Chen, principal trainer & consultant at Shufrans TechDocs received her professional on-the-job training in the field of STE under the tutelage of Dr Frans Wijma, a linguist and documentation expert. Together as an experienced global team, they provided their combined knowledge and dedication to benefit customers worldwide. To date, they have provided training and consultancy services to over 180 companies. Shufrans TechDocs is the only company with such vast experience in providing certified STE training.

Shumin has supported various companies with their STE and other documentation needs, based on standards where possible. Although STE was developed for the aerospace industry, more specifically for aircraft maintenance documentation, Shumin found that it made a lot of sense to apply the same principles to other industries and types of documents as well. Few -if any- changes to the specification are necessary to adapt STE to industries ranging from machinery to IT, automotive to medical equipment.
