National Technical Systems Reports Strong Fiscal 2005 Year-End, Fourth Quarter
Results

CALABASAS, Calif.--(BUSINESS WIRE)--May 2, 2005--National Technical Systems,
Inc. (Nasdaq: NTSC) today announced results for its fiscal 2005 year and fourth
quarter ended January 31, 2005. For fiscal 2005, NTS improved its top-line and
bottom-line results with revenues and net income increasing 2.2 percent and 30
percent, respectively, over the prior fiscal year. Total revenues for fiscal
year 2005 were $107.0 million, with net income of $1.7 million, or $0.19 per
basic share and $0.18 per diluted share, compared to total revenues of $104.6
million, with net income of $1.3 million, or $0.15 per basic and $.14 per
diluted share for fiscal year 2004.

According to Chairman Dr. Jack Lin, these results were driven by revenues in the
Engineering & Evaluation segment which increased by $4,826,000 or 8.3% when
compared to the same period in fiscal 2004, primarily due to revenues of
$3,718,000 and $531,000, respectively, in fiscal 2005 from the acquisition of
DTI Holdings, LLC, and the acquisition of a telecommunications test laboratory
in Calgary, Canada. Revenues also increased in the Company's space, automotive
and computer testing business. These increases were partially offset by the
decrease in the passive fiber optic testing business and the decrease in defense
related business at the Camden, Arkansas facility. The decrease in revenues at
the Camden facility resulted from the completion, in fiscal 2004, of a major
contract related to the war on terrorism.

President William C. McGinnis commented, "Due to the successful execution of our
business plan with a focus on operational excellence, increased sales coverage,
the commitment and hard work of the NTS team, and the strategic acquisition of
DTI, we generated record revenues of $107 million in fiscal 2005 and produced
the highest net income in four years, as well as the third consecutive year of
increased earnings per share. We believe that the continued execution of the
business plan, the continued migration of the Technical Solutions group from a
"general services" IT focus to a niche oriented engineering focus, and a
continued emphasis on the generation of new clients, positions us for continued
top-and bottom-line growth in fiscal 2006."

McGinnis said that the Company will also continue to focus on acquiring new
accreditations and approvals for new technology developments such as
certification of fiber to the premise devices and DSL devices. In addition, we
have plans to expand our USB and cable and connector offering to Taiwan, Hong
Kong and mainland China.

For the fiscal 2005 fourth quarter, total revenues were $25.6 million, with net
income of $588,000, or $0.07 per basic and $.06 per diluted share, compared to
total revenues of $24.4 million, with net income of $352,000, or $0.04 per basic
and diluted share for the year-earlier period. The year-over-year increase in
revenues for the fiscal fourth quarter was due to higher revenues from the
Engineering & Evaluation segment, partially offset by lower revenues in the
Technical Solutions segment.

The fully diluted share counts used in calculating earnings per share in the
fourth quarter and fiscal year 2005 were 9,625,000 and 9,566,000, respectively,
and the fully diluted share counts used in the comparable periods of the prior
fiscal year were 9,425,000 and 9,206,000, respectively. The Company's January
31, 2005 balance sheet remained strong, with cash of $6.2 million, total assets
of $66.7 million, shareholders equity of $31.0 million and a current ratio of
3.4:1.

Revenues from Engineering & Evaluation for the fiscal 2005 fourth quarter and
year were $15.9 million and $63.2 million, respectively, compared to $13.8
million and $58.4 million for the year-earlier periods.

Operating income for the fiscal 2005 fourth quarter and year for Engineering &
Evaluation was $1.3 million and $2.9 million, respectively, compared to $509,000
and $2.9 million for the year-earlier periods. Gross margins as a percentage of
revenue for the fourth quarter and fiscal 2005 year rose to 29.4 percent and
27.2 percent, respectively, from 24.9 percent and 26.7 percent for the prior
year periods.

The Engineering & Evaluation segment provides physical testing services which
include simulation of harsh environments such as high/low temperature, shock,
vibration, seismic and electromagnetic interference, and functional testing
which requires equipment such as switches, routers, servers and high bandwidth
access to the Internet to subject telecommunication equipment to a full spectrum
of performance type testing. In addition, this segment provides registration
services which perform quality management audits to ISO 9000, quality training
and laboratory accreditation.

Revenues from Technical Solutions for the fiscal 2005 fourth quarter and year
were $9.7 million and $43.8 million, respectively, compared to $10.7 million and
$46.2 million for the year-earlier periods. The decrease in revenues for fiscal
2005 was due to continued degradation of the IT market staffing business due to
competition from off-shore companies and the loss of certain customers in
geographic areas where the Company discontinued its sales and marketing efforts.


                                      -1-


Operating income (loss) for the fiscal year 2005 fourth quarter and year for
Technical Solutions was ($11,000) and $604,000, respectively, compared to
$93,000 and $272,000 for the year-earlier periods. The year-to-year increase in
operating income was as a result of the decrease in selling and general and
administrative expenses, partially offset by a decrease in gross profit.

The Technical Solutions segment provides a variety of staffing and workforce
management services and solutions, including contract services, temporary and
full time placements to meet its customers' information technology ("IT") such
as help-desk analysts and managers, relational database administrators and
developers, application and systems programmers, configuration and project
managers and engineering service needs.
