AGRICULTURAL SCIENCES
EXAMINATION GUIDELINES
GRADE 12
2021

1. INTRODUCTION
The Curriculum and Assessment Policy Statement (CAPS) for Engineering Graphics and Design outlines the nature and purpose of the subject Engineering Graphics and Design. This guides the philosophy underlying the teaching and assessment of the subject in Grade 12.
The purpose of these Examination Guidelines is to:

• Provide clarity on the depth and scope of the content to be assessed in the Grade 12 National Senior Certificate (NSC) Examination in Engineering Graphics and Design.
• Assist teachers to adequately prepare learners for the NSC examinations.

This document deals with the final Grade 12 external examinations. It does not deal in any depth with the School-based Assessment (SBA), Performance Assessment Tasks (PATs) or final external practical examinations as these are clarified in a separate PAT document which is updated annually.
These Examination Guidelines should be read in conjunction with:

• The National Curriculum Statement (NCS) Curriculum and Assessment Policy Statement (CAPS): Engineering Graphics and Design
• The National Protocol of Assessment: An addendum to the policy document, the National Senior Certificate: A qualification at Level 4 on the National Qualifications Framework (NQF), regarding the National Protocol for Assessment (Grades R–12)
• The national policy pertaining to the programme and promotion requirements of the National Curriculum Statement, Grades R–12

2. ASSESSMENT IN GRADE 12
2.1 Formal assessment in Grade 12
In grade 12 formal assessment (SBA) constitutes 25% and is set and marked internally and moderated externally. The remaining 75% of the final mark for certification in Grade 12 is set, marked and moderated externally

2.2 Format of the question papers for the external examinations in Grade 12
In Grade 12 the formal school-based assessment (SBA) constitutes 25% of the final mark. It is set and marked internally and moderated externally. The remaining 75% of the final mark for certification in Grade 12 consists of a national examination which is set, marked and moderated externally. This external examination consists of TWO PAPERS of 150 marks each. The grand total is 300 marks.
The basic outline of these papers is indicated below:

2.3 Cognitive level weighting
The table below provides a guide for the cognitive level weighting applicable to Paper 1 and Paper 2. The key verb is used as a guide to judge the appropriate cognitive level of a question. The context of the question will provide more details to measure the level of difficulty of a question to place it at the most appropriate level. The marks per cognitive level need to reflect the overall cognitive balance as a percentage (40% knowledge, 40% comprehension and application and 20% analysis, synthesis and evaluation) for each of the question papers. The cognitive levels will be made to scaffold within a question.
Cognitive levels, context words and key verbs for Paper 1 and Paper 2:

THE LEVEL OF DIFFICULTY
Each of the cognitive levels A (basic knowledge), B (comprehension and application) and C (analysis, synthesis and evaluation) is mainly determined by the key verbs used in the questions. The level of difficulty for each of these categories must also be judged based on the context of each question. The level of difficulty will fall into three different categories for each of the cognitive levels, namely difficult, moderate and easy. The weighting of these categories should be equal for each of the cognitive levels.
The following contextual issues need to be considered when assessing a question for its level of difficulty:

• The detail of the knowledge or concepts required in the responses
• The amount/quantity of knowledge or concepts that is needed in the responses
• The complexity of the knowledge or concepts that is required in the responses
• The types and complexity of skills needed to complete the question
• The complexity of the phrasing of a question
• The level of extended thinking needed to respond to a question
• The basic context of a question

Each of the contextual issues above needs to be carefully evaluated in each question to make a judgement on the level of difficulty of a question. This classification of questions needs to be justified by the expected performances and perception of candidates to them.
Refer to previous question papers for some examples in this regard.

3. ELABORATION OF THE CONTENT FOR GRADE 12 (CAPS)

4. CONCLUSION
This Examination Guidelines document is meant to articulate the assessment aspirations espoused in the CAPS document. It is therefore not a substitute for the CAPS document which educators should teach to.
Qualitative curriculum coverage as enunciated in the CAPS cannot be over-emphasised.

NOTE: Any information taken from any supporting documents such as textbooks, journals and even these guidelines should be verified for accuracy and correctness before use in order to avoid dissemination of misleading facts that are not scientifically and practically tested.
