About this exam

Automotive Servicing NC I is a Philippine national certificate under the TESDA qualification framework, aimed at entry-level workers who perform basic servicing and maintenance on light vehicles under supervision. It suits jobseekers entering motor vehicle repair shops, fleet garages, service stations, and casa maintenance bays, as well as experienced helpers who want their skills formally assessed. Assessment combines written multiple-choice questions, a practical demonstration of servicing tasks, and oral questioning by an assessor, so competence is judged on what you can actually do with tools in hand, not recall alone. Coverage spans workplace communication and occupational health and safety, correct use of hand tools, measuring instruments and workshop equipment, preventive maintenance and basic vehicle inspection, engine and engine support systems, electrical and electronic systems, chassis, steering, suspension and brakes, and power transmission and drivetrain servicing. Preparation works best by combining the training regulations and competency-based learning materials from TESDA with supervised shop practice on real vehicles. Practise torqueing to specification, using a micrometer, vernier caliper and feeler gauge, reading wiring diagrams, and performing a scheduled maintenance check from start to finish while narrating your safety practices. The official body publishes current fees, schedule, and assessment center details on its website; confirm these there rather than relying on secondhand information.

What you'll study

Common questions

About Automotive Servicing NC I preparation

What does the assessment actually involve?

Typically three parts: a written multiple-choice test on the knowledge competencies, a practical assessment where you perform servicing tasks on a vehicle or mock-up while the assessor observes, and oral questioning to confirm your understanding of why you did each step. The assessor records whether each competency is demonstrated, so a single weak area can affect the overall result.

How difficult is Automotive Servicing NC I?

It is an entry-level qualification, so the knowledge is basic rather than advanced diagnostics. The challenge is precision and consistency: correct tool selection, accurate measurement, proper torque, and safe work habits under observation. Candidates who have regular shop exposure usually find the practical portion manageable, while those who only studied theory often struggle with hands-on tasks.

How long is the assessment, and how many questions are there?

These details vary by assessment center and schedule, and TESDA publishes the current arrangements through its official channels. Ask your chosen assessment center directly for the session length, the number of written items, and the practical tasks you will be asked to perform so you can prepare accordingly.

What happens if I fail, and can I retake?

Candidates who are not yet competent can normally reapply for assessment after further training or practice, but the exact retake rules, waiting period, and any additional fees are set by TESDA and the assessment center. Confirm the current policy with them before scheduling, and use the feedback from your first attempt to target weak competencies.

In what order should I study the domains?

Start with occupational health and safety and hand tools, because every practical task is judged on those habits. Move to measuring instruments and preventive maintenance, which underpin inspection. Then take engine support systems, electrical systems, chassis, steering, suspension and brakes, and finally drivetrain. This order mirrors how work flows in a real service bay.

What are the most common reasons candidates fail?

Skipping safety practices such as chocks, wheel guards, or PPE; using the wrong tool or forcing it; misreading a vernier caliper or micrometer; ignoring torque specifications; and being unable to explain a step during oral questioning. Poor housekeeping and incomplete documentation of the servicing task also cost marks, since assessors observe the whole performance, not just the finished job.

Do I need work experience before taking the assessment?

Not necessarily. The qualification is competency-based, so what matters is whether you can demonstrate the required skills and knowledge. Many candidates complete a training program or structured shop practice first. If you are self-taught, arrange supervised practice on real vehicles so your technique, measurement accuracy, and safety habits are already consistent before assessment day.

Where do I find the fee, schedule, and assessment centers?

TESDA publishes current fees, schedules, and the list of accredited assessment centers through its official website and regional offices. Contact the center nearest you to confirm availability, requirements, and any documents you must bring. Avoid relying on unofficial social media posts, since amounts and schedules change.

What should I bring and wear on assessment day?

Expect to need valid identification, your application or referral documents, and covered safety shoes. Wear work clothes or coveralls, and bring personal protective equipment such as safety glasses and gloves if the center requires them. Confirm the exact list with your assessment center beforehand, since requirements differ slightly between centers.
