A.Begin the task immediately without comment

B.Listen attentively and ask questions to clarify anything unclear

C.Wait for a written copy before doing anything

D.Delegate the task to a colleague

Explanation: Receiving verbal instructions requires listening attentively, correctly interpreting the information, and seeking clarification whenever any instruction is not clear, before acting on it.

A.Discard the instructions immediately

B.Give feedback to the workplace supervisor based on the instructions received

C.Wait for the next work order without reporting

D.Record the instructions in a personal diary only

Explanation: Workplace communication practice requires that feedback is given to the supervisor based on the instructions or information received, closing the loop on the assigned task.

3Which document is an example of a written instruction a plumber might receive on a construction site?

A.A supervisor's memorandum

B.A weather forecast

C.A newspaper advertisement

D.A personal shopping list

Explanation: Supervisor's or manager's instructions, memoranda, and approved work plans are all examples of written instructions used to direct work on a construction site.

4In a construction team, why is it important to clearly define individual roles and responsibilities before starting a plumbing job?

A.So that only the team leader has any responsibility

B.So team members understand what is expected of them and how they report to others

C.So workers can ignore instructions from anyone but themselves

D.So that no records of the work need to be kept

Explanation: Defining individual roles, responsibilities, and reporting relationships allows each team member to know what is expected of them and to whom they report, preventing confusion and duplicated or missed work.

5A plumbing apprentice notices that a task instruction printed in the site manual conflicts with what the supervisor said verbally. What is the most appropriate action?

A.Follow the manual and ignore the supervisor

B.Follow the verbal instruction without question

C.Seek clarification from the supervisor to resolve the conflict before proceeding

D.Perform the task using whichever method is faster

Explanation: Workplace communication practice requires clarification from the supervisor whenever instructions or information are unclear or conflicting, rather than guessing or picking a method arbitrarily.

6Which of the following best describes the correct sequence when a plumbing worker receives written notices at the start of a shift?

A.Act immediately, then read the notice afterward for confirmation

B.Read and interpret the notice correctly, follow the routine instructions in sequence, then give feedback to the supervisor

C.Pass the notice to another worker without reading it

D.File the notice away and continue with yesterday's task list

Explanation: The performance sequence for written notices is to read and interpret them correctly, follow routine instructions in the order given, and then provide feedback to the supervisor once the work is done.

7What is the primary purpose of holding regular workplace meetings on a construction site?

A.To let workers socialize with no work-related purpose

B.To allow team members to contribute ideas, receive updates, and have meeting outputs implemented

C.To replace all written instructions permanently

D.To assign blame for mistakes publicly

Explanation: Participating in workplace meetings involves attending punctually, contributing input consistent with the meeting's purpose, and ensuring that agreed outputs are processed and implemented afterward.

8Which communication tool would be most appropriate for a plumber to quickly report an urgent leak discovered while working inside a building under construction?

A.A two-way radio or mobile phone to the supervisor

B.A memo submitted at the end of the month

C.A note left in the site suggestion box

D.An entry in the annual report

Explanation: Urgent workplace communication requires immediate channels such as a mobile phone or two-way radio so the supervisor can respond to the hazard without delay.

9What should a team member do if instructions from the site supervisor and instructions from a co-worker conflict?

A.Follow the co-worker because they are more experienced

B.Clarify the conflict with the supervisor, since the supervisor has reporting authority

C.Ignore both and do nothing

D.Do both instructions simultaneously

Explanation: The formal reporting relationship on a site places the supervisor as the authority for resolving conflicting directions, so clarification should be sought from the supervisor.

10A plumbing crew is asked to record workplace data as part of completing written documentation. Why is this practice important?

A.It has no real value and is only for appearances

B.It provides an accurate record that supervisors and other workers can rely on for decisions and accountability

C.It replaces the need for any verbal communication

D.It is only required once a year

Explanation: Completing written documentation, such as recording workplace data, creates an accurate record that supports decision-making, accountability, and continuity when passed on to other personnel.

About the BTEB Plumbing Exam

The BTEB National Skill Certificate-I in Plumbing (Construction Sector) is a competency-based trade qualification (Qualification Code CONPLM020112A) certifying basic-worker-level competence in plumbing. It combines generic workplace skills (communication, teamwork, housekeeping, OHS), sector-specific skills (construction sector orientation, drawing interpretation, hand/power tools) and occupation-specific skills (fabricating pipes, preparing pipes for installation, making pipe joints and connections, and cutting/penetrating walls and floors for plumbing works), assessed through written/oral exams and hands-on demonstration.

Assessment

Competency-based qualification (Qualification Code CONPLM020112A) built from Generic Competencies (Communicate in the Workplace, Work in a Team Environment, Practice Workplace Cleanliness, Practice OHS), Sector-Specific Competencies (Work in the Construction Sector, Interpret Drawings and Specifications, Use Hand Tools and Power Tools) and Occupation-Specific Competencies (Fabricate Pipes, Prepare Pipes for Installation, Make Pipe Joints and Connections, Perform Cutting and Penetration for Plumbing Works), assessed by a BTEB-certified assessor through written/oral exams, demonstration and observation.

Time Limit

Nominal training duration is 360 hours across all generic, sector-specific and occupation-specific units of competency; individual assessment sessions are scheduled by the training institute and BTEB has not published a single fixed exam time limit for NSC-I Plumbing.

Passing Score

Assessment is competency-based: the candidate must be judged competent in every listed unit of competency (not a single aggregate percentage). BTEB has not published a numeric written-paper cut score for this qualification. Confirm current assessment practice with your enrolling institute.

Exam Fee

Registration and assessment fees are set by BTEB and the enrolling institute and are government-subsidised but change periodically. Confirm the current amount with your institute. (Bangladesh Technical Education Board (BTEB))

BTEB Plumbing Study Tips from Top Performers

1Work through the units in the order BTEB structures them: workplace communication and teamwork, housekeeping and OHS first, then construction sector basics and tool use, and finally the four occupation-specific pipe units, since later topics assume the earlier foundation.

2Pair each pipe-fabrication topic with hands-on practice, such as cutting a G.I. pipe within the ±3 mm tolerance, cutting threads with a die stock and oil, or fitting a T-joint, since BTEB assesses practical competence through demonstration alongside theory.

3Learn the specific pipe joint types (T-joint, Y-joint, cross tee-joint) and leak-proofing methods (hemp packing with lead/epoxy caulking for hub joints, couplers for hub-less pipe, Teflon tape for threaded connections) precisely, since exact jointing method matters for both the exam and real leak-free installations.

4Always use the correct PPE for each task, such as goggles and a dust mask when cutting or threading pipe, an earmuff around noisy cutting equipment, and a hard hat and safety belt for wall/floor penetration or elevated work, since safe and correct PPE use is directly tested and expected on the job.
