    NATIONAL TECHNICAL SYSTEMS COMPLETES ACQUISITION OF DTI HOLDINGS, LLC

       Provider of Large Scale Shock and Vibration Tests for U.S. Navy

CALABASAS, CA (January 26, 2004) . . . National Technical Systems, Inc. (Nasdaq:
NTSC)  (NTS),  a leading  provider of  quality,  conformance  and  certification
testing, quality registration, and managed services, announced today that it has
finalized the acquisition of privately-held DTI Holdings, LLC, doing business as
"Dynamic Testing" (DTI), headquartered in Rustburg, VA. Mertz Associates,  Inc.,
a  Milwaukee-based   merger  and  acquisition   consulting  firm,   assisted  in
negotiating the transaction.  As previously  reported,  on December 8, 2003, the
purchase was made for a combination of cash and NTS common stock.

      NTS Chairman and CEO, Jack Lin, Ph.D., commented,  "The acquisition of DTI
is another step in NTS' growth strategy for increasing revenue and profitability
for our shareholders. Not only will this acquisition be immediately accretive in
its own  right,  but it is also  expected  to  play  an  important  role in NTS'
strategy of capturing a significant share of the large-scale shock and vibration
testing mandated by the Navy. The DTI acquisition differentiates NTS as the only
commercial  company able to offer the Navy and its suppliers a complete suite of
physical tests to qualify products for deployment on Naval vessels."

      DTI  provides  its  customers  large-scale  shock  and  vibration  testing
services that are used to qualify mission-critical equipment such as navigation,
communication  and guidance  weapons  installed  on U.S.  Navy  combatants.  Its
customers include the U.S. Navy and other U.S. and foreign government  agencies,
as well as a number  of  prime  contractors  and  commercial  organizations.  In
addition to testing services, DTI also offers its customers a full line of shock
isolators.

      NTS President and Chief Operating  Officer William C. McGinnis added, "DTI
is a healthy  organization  with a strong  management team and a culture that is
compatible with NTS. Its operations are efficient and should immediately provide
higher margins to our organization.  NTS is now positioned to offer the Navy and
its suppliers  complete and  convenient  one-stop  services to meet all the Navy
NAVSEA test  requirements.  One of the jewels of this  acquisition is DTI's $7.0
million  time and  material  task order based  contract  with the Naval  Surface
Warfare Center.  We also believe there is an opportunity to achieve  significant
shock  isolator  product  growth  in the  domestic  and  international  shipping
industry."
