Technical and Training Professionals,
Now is the time to think about bringing an ATI course to your site! If
there are 8 or more people who are interested in a course, you save money if
we bring the course to you. If you have 15 or more students, you save over
50% compared to a public course.
This catalog includes upcoming open enrollment dates for many
courses. We can teach any of them at your location. Our website,
www.ATIcourses.com, lists over 50 additional courses that we offer.
For 24 years, the Applied Technology Institute (ATI) has earned the
TRUST of training departments nationwide. We have presented “on-site”
training at all major DoD facilities and NASA centers, and for a large number
of their contractors.
Since 1984, we have emphasized the big picture systems engineering
- Defense Topics
- Engineering & Data Analysis
- Sonar & Acoustic Engineering
- Space & Satellite Systems
- Systems Engineering
with instructors who love to teach! We are constantly adding new topics to
our list of courses - please call if you have a scientific or engineering training
requirement that is not listed.
We would love to send you a quote for an
onsite course! For “on-site” presentations, we
can tailor the course, combine course topics
for audience relevance, and develop new or
specialized courses to meet your objectives.
P.S. We can help you arrange “on-site”
courses with your training department.
