1. Introduction:
Electronics Engineering is one of the prominent and popular disciplines within engineering and
technology sectors. Many people in the developed countries, developing countries and under
developed countries have given emphasis for the broader application of Electronics Engineering.
This field has been helping the world for the rapid growing electronic items production and has
been providing services in large electronics and communication fields. It has been creating wage
and self employment opportunities immensely both in public and private sectors. This curriculum
is designed to prepare basic level technical workforce equipped with knowledge and skills related
to the field of Electronics Engineering so as to meet the demand of such workforce in the country
to contribute in the national economic development of Nepal. The knowledge and skills
incorporated in this curriculum will be helpful to deliver the individual needs as well national
needs in the field of Electronics Engineering.
The Council for Technical Education and Vocational Training (CTEVT) has been running its pre
SLC intake electronics engineering (Electronics Sub-overseer) programme since 1995 A. D. Till
date, this programme had been revised for one time (2007 A.D.) to incorporate new skills and
technologies. During this second revision, the structure of the curriculum has been changed from
the previous curriculum. Although it follows the same contents as of older version new tasks are
added according to new innovation in this field.
2. Aims:
The aim of this curricular program is to prepare competent basic level workforce in the field of
electronics engineering who can work in rapid growing electronics items manufacturing industries
as well as can provide service in electronics and communication fields.
3. Program objectives:
After the completion of this curricular program, graduates will be able to:
1. Perform basic mechanical fitting practices
2. Perform basic electrical installation
3. Perform basic electronics and computer works
4. Assist to install telecommunication system
5. Repair and maintain radio and television devices and equipments
6. Repair and maintain electronic devices, solar components, and household appliances
7. Install and maintain audio video and multimedia system
8. Create self employment opportunity to reduce the unemployment problems this helps to
alleviate the poverty in the country.
4. Program description:
This course is based on the job required to perform by the Junior Electronics Technicians
(Electronics Sub-overseer) in manufacturing and service sectors. The manufacturing sector
4
includes electronic items production and service sector includes electronics and communication
system installation and maintenance. Therefore, this curriculum is designed to provide knowledge
and skills focusing on Electronics Engineering related to the occupation. The curricular program
consists of two years in house course and five months on the Job Training. The first year courses
are offered focusing on foundational and disciplinary subjects of electronics engineering; the
second year courses are focused on basic disciplinary subjects of Electronics Engineering.
Similarly, the On-the-Job Training (OJT) for 5 months insists on the application of learned skills
and knowledge in formal setting as well as the provision of OJT is also included to establish a
linkage
with employers and provides hands on work experience to students and promotes
employability of graduates. Moreover, OJT takes place immediately after completing second year
final examination.
5. Duration:
This course will be completed within 24 months / 104 weeks / 3120 hours. In addition, 5
months/ 800 hours on-the-job training should also be completed for successful completion of the
course. Moreover, one academic year consists of 39 weeks and one week consists of 40 hours.
6. Target group:
The target group for this training will be all the interested individuals of the country with
academic qualification of class 10 pass (Sent up). Preference will be given to the individuals of
rural, poor, female, Dalit, Janjati, Disadvantaged Groups (DAGs), conflict affected people and
the disables.
7. Group size:
The group size will be maximum of 24 (Twenty four) in a batch.
8. Target location:

The following instructional media and materials are suggested for the effective instruction and
demonstration.
Printed Media Materials (Assignment sheets, Case studies, Handouts, Information sheets,
Individual training packets, Procedure sheets, Performance Check lists, Textbooks etc.).
Non-projected Media Materials (Display, Models, Photographs, Flip chart, Poster, Writing
board etc.).
Projected Media Materials (Opaque projections, Overhead transparencies, Slides etc.).
Audio-Visual Materials (Audiotapes, Films, Slide-tape programs, Videodiscs, Videotapes
etc.).
Computer-Based Instructional Materials (Computer-based training, Interactive video etc.)
or training institution).
17. Teaching learning methodologies:
The methods of teachings for this curricular program will be a combination of several approaches.
Such as Illustrated Lecture, Group Discussion, Demonstration, Simulation, Guided practice,
6
Practical experiences, Fieldwork, Report writing, Term paper presentation, Case analysis,
Tutoring, Role-playing, Heuristic and Other Independent learning.

OJT
18. Evaluation scheme:
Continuous evaluation of the students' performance is to be done by the related
instructor/ trainer to ensure the proficiency over each competency under each area of a
subject specified in the curriculum.
Related technical knowledge learnt by students will be evaluated through written tests.
Students must score a minimum mark of 40% in theory test and 60% in practical test in
all subjects.
There will be three internal assessments and one final examination in each subject.
Moreover, the mode of an assessment and an examination includes both theory and
practical or as per the nature of instruction as mentioned in the curriculum structure.
Students should pass internal assessments both in theory and practical tests in all subjects.
The ratio between the theory and practical tastes will be 20:80 in case of a practical nature
subject.
Out of 100%, 50% weightage is allotted for the internal assessments and the remaining is
allotted for the final examination
The on-the-job training has to be evaluated keeping 500 as full marks. The evaluation of
the performance of the student is to be carried out by the three agencies; the concerned
institute, industry/organization where the student worked and the CTEVT unless
otherwise directed by office of the controller of examinations /Technical Division of the
CTEVT. Here also the student has to score 60% or above for successful completion of
the course.
19. Grading system:
The grading system will be as follows:
Grading
Overall marks
Distinction
