Introduction:

The competency based and market oriented Curriculum for TSLC in Electrical Engineering is designed to

produce competent skillful work force equipped with knowledge, skills and attitudes. This curriculum

focuses on the basic electrical works to contribute in the national streamline of the use of electrical

engineering equipment, repair and maintenance of electrical devices used in the country. At the same time,

this curriculum aims at offering ample of opportunities for employment in the related sector, mainly

entrepreneurship development of the graduates as well as the employment in the national and international

job market.

Aim of the Course:

The aim of the course is to produce competent human resources in the electrical engineering field who will be able to provide services in different communities as well as in the national & international job markets.

Overall Objective: At the end of the course, the graduates will be able to support in providing the electrical installation,

electrical fault finding and repair and maintenance services in individual household, public sectors as well as

national and international job market.

Specific Objectives:

After the completion of the course the graduates will be able to:

• Install basic electricity • Perform basic electrical functions • Repair and maintain electrical devices • Repair and maintenance of electrical equipment • Operate basic computer applications • Perform designing in computer (Auto CAD) • Find fault in refrigeration & air conditioning system • Repair and maintain faults of electrical system • Assemble /disassemble compressor • Install window and split type air conditioning • Familiarize with electrical, electrical and electronics components related with electrical system • Familiarize with basic computer and computerized drawing system

Course Description:

The world is using many electrical appliances and equipment. We cannot imagine the world without

electrical devices. Even though Nepal is lacking to produce basic level electrical workforce in the country,

especially in the grass-root level of rural and urban communities. Training of this level of electrical

workforce, called TSLC in Electrical Engineering presently becomes one of the major responsibilities of

CTEVT. By doing so, Institute of Engineering can concentrate in preparing higher-level skilled human

resources needed for the country. Thus, with the joint effort by CTEVT and Institute of Engineering, TU and

engineering faculties of all universities of the country together walk to materialize the concept, skill for all.

In this new concept, it will become more necessary or produce a huge number of TSLC in Electrical

Engineering to meet the target of the country without compromising quality of the training. To do so,

4

CTEVT and private training institutions accredited by CTEVT are starting to work for this great challenging

task. In this context a well-developed curriculum is a fundamental pre-requisite for the training program. The

foundation of the curriculum is the results of the DACUM workshop for TSLC in electrical engineering,

conducted in January 2007. The DACUM workshop produces an up-to date list of tasks performed by

workers in Electrical Sub-overseer occupation and provides a valuable insight into what actually

suchoccupation requires. The next phase of developing this curriculum consisted of validating the task lists

with a larger sample of electrical workforce and their users.

Having with the feedbacks after the successful implementation of this curriculum, CTEVT Curriculum

Development Division organized a seminar of subject experts of long experience in the field. The experts

rigorously worked on it and the curriculum is the outcome. It is believed that this revised curriculum of

TSLC in Electrical Engineering will correct all the observed shortcomings.

Mostly the trained graduates are employed in the world of work, national and international electrical

organizations working as a basic level electrical workforce and rest are employed in NGOs and INGOs,

which are working for the development of community of Nepal as well as in the international labour market

and some of them are working as entrepreneurs placing emphasis on the preventive care and repair and

maintenance of electrical devices.

Hence this curriculum is designed to implement in the technical schools under the CTEVT to produce TSLC

graduate in Electrical Engineering in the country. These workforces will be the key persons to provide

preventive care,repairing and maintaining services in the peripheral level.

The candidates for the course are selected from the students who have passed the tenth grade schoolingneed

to go to 29 month training in the training institution including 5 months OJT. However all the candidates

irrespective of their schooling will be required to take an entrance examination to assess their aptitude in the

field. The candidates will be finally selected on the basis of the merit list. The applicants should be

physically sound and mentally matured having not less than 16 years of age. Such students from rural

community might get the preference.

Course Duration

This course will be completed within 29 months/124 weeks/3920 hours; including 20 weeks (800

hours) On the Job Training (OJT) with supervision. The 5 months (800 hours) OJT will be

compulsory after completing the final exam.

5

Evaluation Scheme

a. Regular internal evaluation of the trainees is to be conducted by the related instructors to ensure the proficiency over each task/ skill in each subject.

b. Related technical knowledge of the tasks learnt by the trainees is to be evaluated through the written test. Internal assessment will be conducted 3 times by the institute within the training period.

c. The 80% marks are allotted to the practical work and 20% is allotted to the related technical knowledge in each subject.

d. Controller of Examination, CTEVT will conduct the final examination after completion of the course.

e. For each subject, 50 % of the weight age will be allocated to the internal assessment and the rest of the 50 % to the final examination. Both marks will be shown in the Mark-Sheet, but the trainees must separately pass in each evaluation/exam.

f. The overall mark comes from adding the weight age score from internal assessment and mark from the assessment. Only the students who have passed the internal assessment can appear in the final exam.

g. Students should secure 40% marks in theory and 60% marks in practical to pass the internal and final exam.

h. Candidates who fail in the final exam can appear in the re-test scheduled by CTEVT. i. After completion of the final examination On the Job Training (OJT) will be administered.

Eligibility for Admission

Ten class (test)pass

Admission Criteria

Candidates will be selected on the basis of entrance examination conducted by CTEVT.

Pattern of Attendance

Every student must have minimum of 80% attendance in theory and 90% attendance in practical to

appear in internal and final examinations.

Grading System

The grading system will be as follows: Grading overall marks Distinction 80% or above First division 75% to below 80% Second division 65% to below 75% Third division Pass aggregate to below 65%

Certification

The Council for Technical Education and Vocational Training will award Technical School Leaving Certificate in "Electrical Engineering" to the candidate who successfully completes the requirements as prescribed by the curriculum.

6

Career Path

The graduate will be eligible for the position equivalent to Non-gazetted 2nd class/level 4 (technical) as an Electrical Sub-overseer or as prescribed by the Public Service Commission. The graduate will be eligible to appear in the entrance examination of Diploma in Electrical Engineering.
