Teaching Science and Technology Inc. (TSTI)

Teaching Science and Technology, Inc. (TSTI) is a veteran-owned small business that assists companies and organizations who wish to improve their systems engineering skills as they relate to the space domain. We present quality short courses and workshops in space systems engineering and program management to customers around the world. Our teaching style is highly interactive with emphasis on learning-by-doing and practical real-world examples and applications. Our systems engineering courses provide the processes, tools, and information necessary to “jump-start” new-hires to the space business or improve the performance of mid- to senior-level engineers, systems engineers, and technical program managers. In addition, we provide focused systems engineering support to organizations as they approach critical events in the development process and work as red team support. We wrote the books that describe SE in the space domain, and we’ve all had practical SE and PM experience in the development world.

We are happy to travel to your location around the world to help you develop your space expertise.

What Sets Our Astronautical Courses Apart:

  • CREDIBILITY: We wrote the books. We’ve been there, done that. We bring extensive systems engineering experience.
  • COMPETENCE: We’re professional teachers. This is our day job. We take the complex and make it simple. We’re explainers and motivators. Hands-on exercises ensure that you learn space by doing space. No death by PowerPoint.
  • CURRICULUM: We take you from new hire to seasoned space professional. Our on-line learning portal enables continuity through your increasing levels of expertise.
  • COST: We’re small, with low overhead, and come to you. Your cost is 50% less – you can train twice the people for the same price.
  • CONTRACTING: You can get on contract in minutes! We’re only a credit card purchase away.
