INTRODUCTION

Competency based curriculum for Electrical Technician Course (Formerly known as EW&SEA course now renamed as Electrical Technician) had been developed for two year course (+2 level) in Intermediate education. It is designed to ensure that a student acquires knowledge and skills as required to perform a given job in a more effective way.

Competency is the ability to perform a specific task or job in an acceptable way. The “Competency based education” establishes a direct link between the theory and skills expected. It provides adequate scope for self and wage employment. Competency based vocational education paves the way to

(1) Identify the competencies required for a particular job

(2) Prepare the student to learn objectives in a precise way

(3) To make the student to know the reality or world of work

When learning deals with the performance of critical activities, it is necessary to analyse each job keeping in view the technology in force. Teaching and skill learning should be arranged in a systematic manner. In this process, identification of competencies to be attained by the student is a prerequisite condition. Accordingly, the designed curriculum has the following (components).

(1) Job opportunities identified

(2) Identification of duties to be performed in the world of work

(3) The desired knowledge and skill levels to be taught/learned.

(4) List of course objectives.

Skills and techniques for performing a job varies with the change in technology. This necessitates the training of the skilled personnel in emerging areas of critical importance. Therefore, it becomes necessary to revise the curriculum to meet the present requirements. Hence, it is decided to review, revise and reorganize the existing curriculum in “Electrical Wiring & Contracting/Electrical Domestic Appliances and Rewinding” developed in March 1984 and revised during the year 2000.

The exercise of developing competency based curriculum on /Electrical wiring and servicing of Electrical Appliances/ Electrical Technician” is a fruitful venture for making vocational courses as employment oriented and useful to the students and teachers, teacher educators, curriculum planners, educational planners and employers.

Board of Intermediate Education with the co-ordinated efforts of SIVE and other Vocational Lecturers and subject experts has taken up the revision of the curriculum to suit the present day requirements.
