Computer Systems Servicing NC II | Modules and Assessment

Computer Systems Servicing NC II is the TESDA qualification for assembling and configuring computers, setting up networks and servers, and maintaining and repairing computer systems and networks. The TESDA Online Program (TOP) has free modules for it. Finishing those modules does not give you a National Certificate (NC).

The details below come from the Training Regulation amended in December 2013, the PDF published by TESDA. The five modules are the ones listed in the TOP catalog on 21 October 2026, under the folder Computer System Servicing NC II. SiteDecide is an independent educational information resource and is not affiliated with TESDA. Check e-tesda.gov.ph/course before you enroll, because the catalog changes.

If you are still choosing a course, start with the free TESDA online courses guide.

What is Computer Systems Servicing NC II?

Computer Systems Servicing NC II, often shortened to CSS NC II, is a qualification in the electronics sector. The Training Regulation says a person needs the competencies to install and configure computer systems, set up computer networks and servers, and maintain and repair computer systems and networks.

The spelling differs on TOP. Computer Systems Servicing NC II is the title in the Training Regulation. Computer System Servicing NC II is the folder name in the catalog as of 21 October 2026. This guide uses both names for the same qualification.

The regulation says a person who achieves this qualification is competent to be:

Computer Assembler
Computer Service Technician
Network Technician
Computer Maintenance Technician

That describes the work the qualification covers. It is not a job offer. Hiring still depends on the employer, your experience, and the work available.

The curriculum in the regulation is 280 training hours: 40 hours of basic competencies, 80 hours of common competencies, and 160 hours of core competencies. Those hours belong to a registered training program under the Training Regulation. They are not the length of each TOP module. The online courses are self-paced.

What are the five TOP modules?

These are the modules in the folder on 21 October 2026. The last four match the four core units. The first is an introduction module in the catalog. It is not a separate core unit in the Training Regulation.

TOP module	Training Regulation unit
Introduction to Computer Systems Servicing	Introduction module in the TOP folder. Not a separate core unit.
Installing and Configuring Computer Systems	Install and configure computer systems (ELC724331)
Setting Up Computer Networks	Set-up Computer Networks (ELC724332)
Setting Up Computer Servers	Set-up Computer Servers (ELC724333)
Maintaining Computer Systems and Networks	Maintain and Repair Computer Systems and Networks (ELC724334)

Finishing the modules can give you an e-certificate of completion when the course includes one. That is not an NC. The difference is explained in how to download and verify a TESDA e-certificate.

Introduction to Computer Systems Servicing

This is the first module in the folder. The Training Regulation does not describe the lessons inside that online module, so this guide does not list its videos or quizzes. Read the course page on e-tesda.gov.ph before you enroll.

The next four modules match the core competencies. National assessment is based on those units.

Installing and Configuring Computer Systems

This unit is for desktop and workstation computers. The regulation covers assembling hardware, installing an operating system and peripheral drivers, installing application software, and testing and documentation.

The tasks are:

Assemble the computer hardware, including BIOS configuration, while following safety procedures.
Prepare the installer, including a portable bootable device, according to the software instructions.
Install the operating system and drivers, then the updates or patches the manufacturer recommends.
Install application software according to the installation guide, the end user’s requirements, and the license agreement.
Test the system, including a stress test, and forward the documentation.

The regulation’s range lists Windows, Mac OS X, and Linux as operating systems. Application software in that range includes productivity tools, utilities such as anti-virus and disk management, and games. The software used in an assessment depends on the task and on what the center provides.

Setting Up Computer Networks

This unit is for LAN and small-office home-office (SOHO) networks. It covers installing network cables, network configuration, router, Wi-Fi, wireless access point, or repeater configuration, and inspection and testing.

The tasks in the regulation are:

Plan the cable route from the network design and the actual site.
Splice copper cable to EIA/TIA standards. The regulation’s range names straight-through, cross-talk, and roll-over.
Install network cables and cable raceway. The materials include copper cable and terminated fiber optic cable.
Configure the network interface card and check communication between terminals.
Configure the LAN port, WAN port, wireless settings, and security, firewall, or advance settings.
Inspect and test the network, then prepare a report.

The unit includes personal protective equipment and 5S. Excess materials are disposed of under WEEE and 3Rs, as stated in the regulation.

Setting Up Computer Servers

This unit is about setting up computer servers for a LAN or a SOHO network. It is not a full data-center course. The regulation has three parts:

User access. Create a user folder, configure the access level, and run a security check against the network access policy or the end user’s requirements.
Network services. Check that the server starts and connects normally, install or update the required modules, configure the services the task requires, and check that they work.
Testing, documentation, and pre-deployment. Check operation and security, then complete the reports.

The regulation’s range of network services includes remote access, a domain controller, web services, database services, a proxy server, and sharing of files, printers, and other resources. One assessment task does not have to include every service on that list. The services are confirmed from the user or system requirements.

Pre-deployment in the range means installing an application and populating a database.

This unit matters if you already hold Computer Hardware Servicing NC II. The regulation still requires assessment for this certificate of competency. That path is explained below.

Maintaining Computer Systems and Networks

The TOP module is titled “Maintaining Computer Systems and Networks.” The unit in the regulation is Maintain and Repair Computer Systems and Networks. It covers both maintenance and repair.

The five parts are:

Plan and prepare tools, materials, and safety procedures from the job or service order.
Maintain computer systems and networks, including scheduled or periodic maintenance, and repair or replace parts when needed.
Diagnose faults. The range covers network connectivity, software issues, and hardware issues.
Correct defects. Replace or repair defective parts without damaging the surrounding setup, and make adjustments when needed.
Inspect and test, clean the work site, dispose of excess materials under WEEE and 3Rs, and complete the report.

Maintenance in the range includes software updates, hard disk maintenance, and file backup or restoration.

Basic and common competencies are part of the qualification

The qualification is not only the four core units. Section 1 of the regulation also includes basic and common competencies. Assessment focuses on the core units. The basic and common units are integrated, or assessed at the same time as the core units.

Basic competencies, 40 hours:

Participate in workplace communication
Work in a team environment
Practice career professionalism
Practice occupational health and safety procedures

Common competencies, 80 hours:

Apply quality standards
Perform computer operations
Perform mensuration and calculation
Prepare and interpret technical drawing
Use hand tools
Terminate and connect electrical wiring and electronic circuits
Test electronic components

Who should take it?

Take it if you want to service computers and small networks, not only use office apps. It fits work in computer assembly, computer service, network setup, or maintenance, which are the four roles named in the regulation.

For training, the regulation’s entry requirements are:

You can communicate orally and in writing
You must pass the trainability or aptitude test

That list does not include educational attainment or work experience. A school or training center can still add those. Ask the center before you enroll in a face-to-face program.

For assessment, TESDA’s regulation says these people may apply:

Graduates of formal, non-formal, and informal training, including enterprise-based programs
Experienced workers, whether employed or self-employed

TESDA’s documentary requirements for a new applicant do not include the TOP e-certificate. The modules help when the lessons match the qualification. They do not replace assessment. The application steps are in how to get a National Certificate.

If you already have Computer Hardware Servicing NC II

Computer Hardware Servicing NC II is the earlier qualification named in section 4.3 of the regulation. If you already hold an NC or a COC for it:

Portfolio assessment can apply to COC 1 (install and configure computer systems), COC 2 (set-up computer networks), and COC 4 (maintain and repair), if you are employed and have at least three years of related experience.
If the assessor finds the evidence short, you can still be asked for a practical demonstration, a third-party report, or other evidence.
You must take the assessment for COC 3, Set-up computer servers.

Confirm this with the assessment center. Bring the older certificate.

What the assessment covers

To receive the National Certificate, you must show competence in every unit listed in Section 1. The regulation says successful candidates receive a National Certificate signed by the TESDA Director General.

You can also earn a Certificate of Competency (COC) for each core unit:

Install and configure computer systems
Set-up computer networks
Set-up computer servers
Maintain and Repair Computer Systems and Networks

When all of those COCs are accumulated and submitted, TESDA issues the National Certificate.

This is what each core unit’s evidence guide says must be shown:

Core unit	What must be shown	How the assessor may assess you
Install and configure computer systems	Hardware assembled; operating system and drivers installed; application software installed; testing and documentation done	The assessor may choose any two of practical demonstration with oral questioning, interview, and portfolio
Set-up computer networks	Network cables installed; network configuration set; router, Wi-Fi, wireless access point, or repeater set; network inspected and tested	The assessor may choose any two of practical demonstration with oral questioning, interview, third party, and portfolio
Set-up computer servers	User access set up; network services configured; testing, documentation, and pre-deployment done	The assessor may choose any two of practical demonstration with oral questioning, interview, and portfolio
Maintain and repair computer systems and networks	Maintenance and repair planned; systems and networks maintained; faults diagnosed; defects corrected; systems inspected and tested	The assessor must choose two of observation with oral questioning, interview, and portfolio

Assessment may be in the workplace or in a simulated environment. Practical demonstration is one of the methods for every core unit, along with the interview or portfolio listed in the table.

TESDA publishes a Self-Assessment Guide for this qualification. It is a checklist you complete before assessment. Download the Computer Systems Servicing NC II guide from the Self-Assessment Guides page. The center can also give you the form.

There is an assessment fee. It is separate from free TOP enrollment. The amount follows the fee the TESDA Board set for the qualification. Check the Promulgated Assessment Fees list, then confirm the amount with the center before you pay.

Choose a center accredited for Computer Systems Servicing NC II, not only for a different ICT course. Finding a center, what to bring, and how to claim the certificate are covered in how to get a National Certificate.

How to prepare

Open the Computer System Servicing NC II folder on e-tesda.gov.ph and finish the modules if they are still available.
Practice on a real computer, real cables, and a real network device. Assessment is a performance. Watching the online lessons does not by itself show that you can assemble a computer, work with cables, set up a server, or repair a fault.
Complete the Self-Assessment Guide and note the gaps.
If you need a workshop and a trainer, a face-to-face scholarship is a separate application. Slots are limited. The official application page is explained in the free TESDA scholarship guide.
Apply at an accredited assessment center when you can demonstrate the core units.

Frequently asked questions

Does finishing the Computer Systems Servicing TOP modules already give an NC?

No. You may receive an e-certificate of completion. A National Certificate is for someone who passes assessment for the full qualification.

What are the four core units?

Install and configure computer systems, set-up computer networks, set-up computer servers, and maintain and repair computer systems and networks. These are the core competencies in the Training Regulation amended in December 2013.

Who can train or apply for assessment?

For training, the regulation requires that you can communicate orally and in writing, and that you pass the trainability or aptitude test. A training center may add requirements. For assessment, graduates of formal, non-formal, or informal training, including enterprise-based programs, and experienced workers may apply.

Can I earn a COC before the full NC?

Yes. There is a COC for each core unit. When all four are complete and submitted, the National Certificate can be issued, according to the regulation.

Are the online modules enough for assessment?

Not by themselves. The assessor may use a practical demonstration. Practice on the equipment, and check the Self-Assessment Guide before you apply.
