About the Pat Guidelines

As the Engineering Graphics and Design (EGD) PAT is a compulsory national formal assessment task that contributes 25% (i.e. 100 marks) towards a learner's final NSC mark, it is essentially the third NSC examination paper of EGD. All the presentation requirements must therefore be adhered to and, with the exception of the required research, completed at school, under the supervision of the EGD teacher. Each learner must complete the PAT individually and ALL the presentations must be his/her own original work.

The primary purpose of the EGD PAT is to assess content and concept topics which are not assessed in the examination papers. These are

  • The design process
  • The application of the design process
  • The quality and neatness of free-hand, instrument and CAD drawings

The EGD PAT is therefore designed to develop a learner's ability to integrate and apply knowledge and to demonstrate acquired levels of skills and competency.

With the inclusion of the PAT into EGD, the learner is given an opportunity to apply acquired knowledge in a creative way through the design process.

The learner is given an opportunity to complete the PAT in an environment which is more conducive to the creative processes. This environment should therefore provide the learner with easier access to, and a wider variety of, resource material than would be available in a formal examination.

The various components of the EGD PAT give the learner an opportunity to demonstrate the level of drawing skill that has been attained in all the appropriate drawing methods through the presentation of the required drawings. Each EGD PAT consists of TWO parts:

  • PART A: The design process
  • PART B: The working and pictorial drawings

PART A of both PATs requires that the learner demonstrates a clear understanding of, and is able to apply, the design process. As part of the design process, the learner must be able to do the following:

  • Analyse the given scenario and formulate a design brief. Include a list of specifications, constraints and a management plan as part of the design brief
  • Conduct relevant research
  • Use the research in generating a number of ideas/concepts/solutions, analytically and graphically, through comprehensive freehand drawings
  • Select a final solution that demonstrates a clear understanding of the design brief
  • Provide clear evidence of continuous self-assessment during the development of the PAT.

PART B of both PATs requires that the learner demonstrates and provides evidence of a high level of knowledge and understanding of the concepts and content of Engineering Graphics and Design through the presentation of orthographic working drawings and pictorial drawings.

PART A and PART B of both PATs give the learner the opportunity to demonstrate a level of competency and skill that has been attained in the following drawing methods:

  • Freehand drawings, prepared in pencil
  • Instrument drawings, prepared in pencil
  • CAD drawings, prepared using a CAD program
