Course Outline

In Nigeria, Graduates lack the skill level to fit into the work place. Thus there is a need for introductory and specialized courses that will prepare them for the tasks ahead. This is where our specialty is needed most.

Teknitech Engineering Ltd is a leading service provider for Electrical design & drafting services in the Engineering industry. Thus our instructors provide a practical view-point to their training techniques. Our Course contents cut across both the Electrical Design and Drafting specializations. Teknitech Engineering Ltd will provide students with:

  • Course manuals in Hard copy format
