CERTIFICATE ONE

A. INTRODUCTION

i. The review of this syllabus has been generally influenced by the demands of industries due to itscontinuous change as a result of technological advancement and the changing needs of society.It was also influenced by the TVET reforms under the directions of the new educational reformswith the view to opening up further education and training opportunities to TVET graduates.

The certificate ONE syllabus is designed to respond to the following level descriptors:

QUALIFICATION KNOWLEDGE LEVEL SKILLS AND ATTITUDE:

Certificate 1 1. To demonstrate a broad knowledgebase incorporating some technicalconcepts.
