Technical and Training Professionals,
Now is the time to think about bringing an ATI course to your site! If 8 or
more people attend a course your department saves money when we bring the
course to you. If you have 15 or more students, you can save over 50%
compared to the public course.
Upcoming open enrollment dates for many courses are listed. Any of these
courses can be taught at your location. Our website, www.ATIcourses.com,
lists over 50 additional courses you can request.
For 25 years, the Applied Technology Institute (ATI) has earned the TRUST
of training departments nationwide. ATI has presented “on-site” training at all
major DoD facilities and NASA centers, plus a large number of their
contractors. Ask us for references.
Since 1984, we have emphasized the big picture systems perspective in:
• Defense Topics (Radar, Missiles, EW)
• Engineering & Data Analysis
• Sonar & Acoustic Engineering
• Space & Satellite Systems
• Systems Engineering & Project Management
Our instructors love to teach! New topics are constantly added to our list of
courses – please call if you have a scientific or engineering training
requirement that is not listed.
Receive a free quote for an on-site course. Your “on-site”
presentations can be tailored by combining course
topics for audience relevance or by developing
new or specialized courses to meet your
