8. What is CSS NCII?
 Computer Systems Servicing
(CSS NCII) is the upgraded
version of what is then called
Computer Hardware Servicing
(CHS NCII) qualification. During
the late CHS, the qualification
was said to be of the NCII level,
meaning that in a ranking basis,
it is the baseline level.

9. What is CSS NCII?
 Some competencies have the
NCII, NCIII and NCIV levels. CHS
was given an NCII level
because, well, for a fact, it was
not that difficult to pass, but still,
many students and/or even
professionals fail.

10. What is CSS NCII?
 When TESDA decided to
upgrade the CHS competency,
they forgot or maybe they have
just decided not to adjust its
ranking level. Most IT
professionals would certainly
agree that the CSS competency
deserves to be of the NCIV level.

11. What are the differences between
CHS NCII and CSS NCII?
 The old CHS competency covered just
two (2) modules and you are only
expected to perform a couple of
tasks to pass the actual examination.
The examination includes a question
and answer portion before
proceeding with the actual hands-on
configurations and the same goes for
the CSS NCII exam.

12. What are the differences between
CHS NCII and CSS NCII?
 To cope up with the hastened trend
of technology advancement, CSS
was introduced, and instead of
having just two (2) modules, this new
competency has four (4). This seems
to be a great move to ensure that we
are not left behind on what is the new
global standard in technology.

13. OCCUPATIONAL SAFETY AND
HEALTH POLICY AND PROCEDURE
 A planned system of working to prevent
illness and injury where you work by
recognizing and identifying hazards and
risks.
 Health and safety procedure is the
responsibility of all persons in the computer
and technology industries.

14. OCCUPATIONAL SAFETY AND
HEALTH POLICY AND PROCEDURE
 You must identify the hazards where you
are working and decide how dangerous
they are. Eliminate the hazard or modify
the risk that it presents.
