FOREWORD
The provision of quality education and training is fundamental to the Government’s overall
strategy for social economic development. Quality education and training will contribute to
achievement Kenya’s development blue print and sustainable development goals.
Reforms in the education sector are necessary for the achievement of Kenya Vision 2030 and
meeting the provisions of the Constitution of Kenya 2010. The education sector had to be aligned
to the Constitution and this resulted to the formulation of the Policy Framework for Reforming
Education and Training. A key feature of this policy is the radical change in the design and
delivery of the TVET training. This policy document requires that training in TVET be
competency based, curriculum development be industry led, certification be based on
demonstration of competence and mode of delivery allows for multiple entry and exit in TVET
programmes.
These reforms demand that Industry takes a leading role in curriculum development to ensure the
curriculum addresses its competence needs. It is against this background that this Curriculum has
been developed.
It is my conviction that this curriculum will play a great role towards development of competent
human resource for the Electrical sector’s growth and sustainable development.

PREFACE
Kenya Vision 2030 aims to transform the country into a newly industrializing, “middle-income
country providing a high-quality life to all its citizens by the year 2030”. Kenya intends to create
a globally competitive and adaptive human resource base to meet the requirements of a rapidly
industrializing economy through life-long education and training. TVET has a responsibility of
facilitating the process of inculcating knowledge, skills and attitudes necessary for catapulting
the nation to a globally competitive country, hence the paradigm shift to embrace Competency
Based Education and Training (CBET).
The Technical and Vocational Education and Training Act No. 29 of 2013 on Reforming
Education and Training in Kenya, emphasized the need to reform curriculum development,
assessment and certification. This called for a shift to CBET to address the mismatch between
skills acquired through training and skills needed by industry as well as increase the global
competitiveness of Kenyan labor force.
TVET Curriculum Development, Assessment and Certification Council (TVET CDACC), in

conjunction with Electrical Engineering Sector Skills Advisory Committee (SSAC) have
developed this curriculum.
This curriculum has been developed following the CBET framework policy; the CBETA
standards and guidelines provided by the TVET Authority and the Kenya National Qualification
Framework designed by the Kenya National Qualification Authority.
This curriculum is designed and organized with an outline of learning outcomes; Suggested
Methods of Instruction, training/learning resources and methods of assessing the trainee’s
achievement. The curriculum is competency-based and allows multiple entry and exit to the
course.
I am grateful to the Council Members, Council Secretariat, Electrical Engineering SSAC, expert
workers and all those who participated in the development of this curriculum.

ACKNOWLEDGEMENT
This curriculum has been designed for competency-based training and has independent units of
learning that allow the trainee flexibility in entry and exit. In developing the curriculum,
significant involvement and support was received from various organizations.
I recognize with appreciation the role of the Electrical Engineering Sector Skills Advisory
Committee (SSAC) in ensuring that competencies required by the industry are addressed in the
curriculum. I also thank all stakeholders in the Health sector for their valuable input and all
those who participated in the process of developing this curriculum.
I am convinced that this curriculum will go a long way in ensuring that workers in Electrical
Sector acquire competencies that will enable them to perform their work more efficiently.
