CURRICULUM AND ASSESSMENT POLICY STATEMENT (CAPS)
FOREWORD BY THE MINISTER
Our national curriculum is the culmination of our efforts over a period of seventeen
years to transform the curriculum bequeathed to us by apartheid. From the start of
democracy we have built our curriculum on the values that inspired our Constitution
(Act 108 of 1996). The Preamble to the Constitution states that the aims of the
Constitution are to:
• heal the divisions of the past and establish a society based on democratic values,
social justice and fundamental human rights;
• improve the quality of life of all citizens and free the potential of each person;
• lay the foundations for a democratic and open society in which government is
based on the will of the people and every citizen is equally protected by law; and
• build a united and democratic South Africa able to take its rightful place as a
sovereign state in the family of nations.
Education and the curriculum have an important role to play in realising these aims.
In 1997 we introduced outcomes-based education to overcome the curricular divisions of the past, but the experience
of implementation prompted a review in 2000. This led to the first curriculum revision: the Revised National Curriculum
Statement Grades R-9 and the National Curriculum Statement Grades 10-12 (2002).
Ongoing implementation challenges resulted in another review in 2009 and we revised the Revised National Curriculum
Statement (2002) to produce this document.
From 2012 the two 2002 curricula, for Grades R-9 and Grades 10-12 respectively, are combined in a single document
and will simply be known as the National Curriculum Statement Grades R-12. The National Curriculum Statement for
Grades R-12 builds on the previous curriculum but also updates it and aims to provide clearer specification of what is to
be taught and learnt on a term-by-term basis.
The National Curriculum Statement Grades R-12 accordingly replaces the Subject Statements, Learning Programme
Guidelines and Subject Assessment Guidelines with the
(a)
Curriculum and Assessment Policy Statements (CAPS) for all approved subjects listed in this document;
(b)
National policy pertaining to the programme and promotion requirements of the National Curriculum Statement
Grades R – 12; and
(c)

CURRICULUM AND ASSESSMENT POLICY STATEMENT (CAPS)
SECTION 1
INTRODUCTION TO THE CURRICULUM AND ASSESSMENT POLICY STATEMENTS FOR TECHNICAL SCIENCES
GRADES 10 – 12
1.1Background
The National Curriculum Statement Grades R – 12 (NCS) stipulates policy on curriculum and assessment in the schooling
sector. To improve implementation, the National Curriculum Statement was amended, with the amendments coming into
effect in January 2012. A single comprehensive Curriculum and Assessment Policy document was developed for each
subject to replace Subject Statements, Learning Programme Guidelines and Subject Assessment Guidelines in Grades
R – 12.
1.2Overview
(a)
The National Curriculum Statement Grades R – 12 (January 2012) represents a policy statement for learning
and teaching in South African schools and comprises the following:
(i) Curriculum and Assessment Policy Statements for each approved school subject;
(ii) The policy document, National policy pertaining to the programme and promotion requirements of the
National Curriculum Statement Grades R – 12; and
(iii) The policy document, National Protocol for Assessment Grades R – 12 (January 2012).
(b)
(c)
The National Curriculum Statement Grades R – 12 (January 2012) replaces the two current national curricula
statements, namely the
(i) Revised National Curriculum Statement Grades R – 9, Government Gazette No. 23406 of 31 May 2002,
and
(ii) National Curriculum Statement Grades 10 – 12 Government Gazettes, No. 25545 of 6 October 2003 and
No. 27594 of 17 May 2005.
The national curriculum statements contemplated in subparagraphs b (i) and (ii) comprise the following policy
documents, which will be incrementally repealed by the National Curriculum Statement Grades R – 12 (January
2012) during the period 2012 – 2014:
(i) The Learning Area/Subject Statements, Learning Programme Guidelines and Subject Assessment
Guidelines for Grades R – 9 and Grades 10 – 12;
(ii) The policy document, National Policy on assessment and qualifications for schools in the General Education
and Training Band, promulgated in Government Notice No. 124 in Government Gazette No. 29626 of 12
February 2007;
(iii) The policy document, the National Senior Certificate: A qualification at Level 4 on the National Qualifications
Framework (NQF), promulgated in Government Gazette No.27819 of 20 July 2005;CAPS)
(iv) The policy document, An addendum to the policy document, the National Senior Certificate: A qualification at
Level 4 on the National Qualifications Framework (NQF), regarding learners with special needs, published
in Government Gazette, No.29466 of 11 December 2006, is incorporated in the policy document, National
policy pertaining to the programme and promotion requirements of the National
CAPS

Curriculum Statement Grades R – 12; and
(v) The policy document, 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), promulgated in Government Notice No.1267 in Government Gazette No. 29467 of 11
December 2006.
(d)
The policy document, National policy pertaining to the programme and promotion requirements of the National
Curriculum Statement Grades R – 12, and the sections on the Curriculum and Assessment Policy as contemplated
in Chapters 2, 3 and 4 of this document constitute the norms and standards of the National Curriculum Statement
Grades R – 12. It will therefore, in terms of section 6A of the South African Schools Act,1996 (Act No. 84 of 1996,)
form the basis for the Minister of Basic Education to determine minimum outcomes and standards, as well as the
processes and procedures for the assessment of learner achievement to be applicable to public and independent
schools.
1.3
General aims of the South African Curriculum
(a)
The National Curriculum Statement Grades R – 12 gives expression to the knowledge, skills and values worth
learning in South African schools. This curriculum aims to ensure that children acquire and apply knowledge and
skills in ways that are meaningful to their own lives. In this regard, the curriculum promotes knowledge in local
contexts, while being sensitive to global imperatives.
(b)
The National Curriculum Statement Grades R – 12 serves the purposes of:
•
equipping learners, irrespective of their socio-economic background, race, gender, physical ability or intellectual
ability, with the knowledge, skills and values necessary for self-fulfilment, and meaningful participation in society
as citizens of a free country;
•
providing access to higher education;
•
facilitating the transition of learners from education institutions to the workplace; and
•
providing employers with a sufficient profile of a learner’s competences.
(c)
The National Curriculum Statement Grades R – 12 is based on the following principles:
•
Social transformation: ensuring that the educational imbalances of the past are redressed, and that equal
educational opportunities are provided for all sections of the population;
•
Active and critical learning: encouraging an active and critical approach to learning, rather than rote and uncritical
learning of given truths;
•
High knowledge and high skills: the minimum standards of knowledge and skills to be achieved at each grade are
specified and set high, achievable standards in all subjects;
TECHNICAL SCIENCES
•
Progression: content and context of each grade shows progression from simple to complex;
•
Human rights, inclusivity, environmental and social justice: infusing the principles and practices of social and
environmental justice and human rights as defined in the Constitution of the Republic of South Africa. The National
Curriculum Statement Grades R – 12 is sensitive to issues of diversity such as poverty, inequality, race, gender,
language, age, disability and other factors;
•
Valuing indigenous knowledge systems: acknowledging the rich history and heritage of this country as important
contributors to nurturing the values contained in the Constitution; and
•
Credibility, quality and efficiency: providing an education that is comparable in quality, breadth and depth to those
of other countries.
6
CURRICULUM AND ASSESSMENT POLICY STATEMENT (CAPS)
(d)
The National Curriculum Statement Grades R – 12 aims to produce learners that are able to:
•
identify and solve problems and make decisions using critical and creative thinking;
•
work effectively as individuals and with others as members of a team;
•
organise and manage themselves and their activities responsibly and effectively;
•
collect, analyse, organise and critically evaluate information;
•
communicate effectively using visual, symbolic and/or language skills in various modes;
•
use science and technology effectively and critically, showing responsibility towards the environment and the
health of others; and
•
demonstrate an understanding of the world as a set of related systems by recognising that problem solving
contexts do not exist in isolation.
(e)
Inclusivity should become a central part of the organisation, planning and teaching at each school. This can only
happen if all teachers have a sound understanding of how to recognise and address barriers to learning, and how
to plan for diversity.
The key to managing inclusivity is ensuring that barriers are identified and addressed by all the relevant support
structures within the school community, including teachers, District-based Support Teams, Institutional-level, Support
Teams, parents and Special Schools as Resource Centres. To address barriers in the classroom, teachers should use
various curriculum differentiation strategies such as those included in the Department of Basic Education’s Guidelines
for Inclusive Teaching and Learning (2010).

THE AIMS AND PURPOSE OF TECHNICAL SCIENCES
The main aim of Technical Sciences is to support learners in the three focus areas of technology, namely Mechanical
Technology, Electrical Technology and Civil Technology. Learners will have an NQF level 4 competence in Technical
Science.
Learners at Technical High Schools will be able to integrate scientific knowledge in a more informed way in their subject
offerings in technology. Scientific concepts and skills will be more accessible to learners that have a technical orientation
in schooling. Technical Sciences will address the needs of the industry and the technology subjects by being an enabling
subject to promote technology study in schools.
Skills that learners will acquire include classifying, communicating, measuring, designing an investigation, drawing
and evaluating conclusions, formulating models, hypothesizing, identifying and controlling variables, observing and
comparing, interpreting, predicting, problem-solving and reflecting. The main skills will be practical application and
observing simulations.
Technical Sciences will prepare learners for further education and training, employment, citizenship, holistic development
and socio-economic development. Learners choosing Technical Sciences as a subject in Grades 10 – 12 will have
improved access to applied technology courses, vocational career paths and entrepreneurial opportunity. Technical
Sciences will also promote skills development in the fields of technology, thus promoting economic growth and social
well-being of more citizens in our country.
The six main knowledge areas that Technical Sciences comprises of are:
•
Mechanics
•
Matter and Materials
•
Electricity and Magnetism
•
Waves, Sound and Light
•

2.6 OVERVIEW OF FORMAL ASSESSMENT AND RECOMMENDED INFORMAL EXPERIMENTS
For Grades 10 and 11, FOUR prescribed experiments are done per year as formal assessment (one experiment per
term for terms 1 to 4). For Grade 12, THREE prescribed experiments are done per year as formal assessment (one
experiment per term for terms 1, 2 and 3). TWO control tests and TWO examinations are written as formal assessment
in each of Grades 10 and 11. ONE control test, ONE midyear examination, ONE trial examination and ONE final
examination are written as formal assessment for Grade 12.
ONLY in Grade 10 and Grade 11, ONE project is done per year as formal assessment or an integrated Chemistry/
Physics project (started in term 1 and assessed in term 3). Any ONE of the recommended projects can be done or any
ONE of the experiments can be done as a practical investigation, or any other topic of choice can be used as a project.
It is recommended that the project topic is given to learners early in the first term so that learners can start the project.
The final assessment of the project is done and recorded in the third term. In Grade 12 NO project is done.
There are 11 informal experiments for Grade 10, nine recommended informal experiments for Grade 11 and nine
recommended informal experiments for Grade 12.

The Parallelogram law of forces states that if
two forces acting at a point can be represented
by the adjacent sides of a parallelogram both
in magnitude and direction, then the diagonal
from the point gives the resultant of the two

State Newton’s first law: An object continues in
a state of rest oruniform (moving with constant)
velocity unless it is acted upon by an unbalanced
(net or resultant) force.
Define inertia as the property of a body to resist
any change in its state of motion or rest.
Define mass as a measure of the inertia of a
body.
SI unit is kg.
Give examples to illustrate Newton’s first law.
Define acceleration as the rate of change of
velocity.
SI unit is m.s-2
•
State Newton’s second law: When a net force,
Fnet, is applied to an object of mass, m, it
accelerates the object in the direction of the net
force.
Fnet = ma
SI unit is N.

Newton’s Third Law of
Motion
•
State Newton’s third law:
When object A exerts a force on object B,
object B simultaneously exerts an oppositely
directed force of equal magnitude on object A.
•
Give examples to illustrate Newton’s third law,
using action-reaction pairs.

SECTION 4
4.ASSESSMENT
4.1Introduction
Assessment is a continuous planned process of identifying, gathering and interpreting information about the performance
of learners, using various forms of assessment. It involves four steps: generating and collecting evidence of achievement;
evaluating this evidence; recording the findings; and using this information to understand and thereby assist the learners’
development in order to improve the process of learning and teaching.
Assessment should be both informal (Assessment for Learning) and formal (Assessment of Learning). In both cases
regular feedback should be provided to learners to enhance the learning experience. Assessment is a process that
measures individual learner’s attainment of knowledge (content, concepts and skills) in a subject by collecting, analysing
and interpreting the data and information obtained from this process to:
•
enable the teacher to make reliable judgements about a learner’s progress
•
inform learners about their strengths, weaknesses and progress
•
assist teachers, parents and other stakeholders in making decisions about the learning process and the progress
of the learners.
Assessment should be mapped against the content, concepts and skills, and the aims specified for Technical Sciences,
and in both informal and formal assessments it is important to ensure that in the course of a school year:
•
all of the subject content is covered
•
the full range of skills is included
•
a variety of different forms of assessment are used.
4.2 Informal or daily assessment
Assessment for learning has the purpose of continuously collecting information on a learner’s achievements that can
be used to improve their learning.
Informal assessment is a daily monitoring of learners’ progress. This is done through observations, discussions,
practical demonstrations, learner-teacher conferences, informal classroom interactions, etc. Informal assessment may
be as simple as stopping during the lesson to observe learners or to discuss with learners how learning is progressing.
Informal assessment should be used to provide feedback to the learners and to inform planning for teaching, but need
not be recorded. It should not be seen as separate from learning activities taking place in the classroom. Learners or
teachers can mark these assessment tasks.
Self-assessment and peer assessment actively involves learners in assessment. This is important as it allows learners
to learn from and reflect on their own performance. The results of the informal daily assessment tasks are not formally
recorded unless the teacher wishes to do so. The results of daily assessment tasks are not taken into account for
promotion and certification purposes.
Informal, on-going assessments should be used to structure the acquisition of knowledge and skills and should be
precursors to formal tasks in the Programme of Assessment.

PROGRAMME OF ASSESSMENT
School-based Assessment – SBA
Practical Assessment Task – PAT
Final Examination
25 %
25 %
50 %
All assessment tasks that make up a formal programme of assessment for the year are regarded as Formal Assessment.
Formal assessment tasks are marked and formally recorded by the teacher for progression and certification purposes. All
Formal Assessment tasks are subject to moderation for the purpose of quality assurance and to ensure that appropriate
standards are maintained.
Formal assessment provides teachers with a systematic way of evaluating how well learners are progressing in a grade
and in a particular subject. Examples of formal assessments include tests, examinations, practical tasks, projects, oral
presentations, demonstrations, performances, etc. Formal assessment tasks form part of a year-long formal Programme
of Assessment in each grade and subject.
4.3.1 Control tests & examinations
Control tests and examinations are written under controlled conditions within a specified period of time. Questions in tests
and examinations should assess performance at different cognitive levels with an emphasis on process skills, critical
thinking, scientific reasoning and strategies to investigate and solve problems in a variety of scientific, technological,
environmental and everyday contexts.
4.3.2 Practical investigations & experiments
Practical investigations and experiments should focus on the practical aspects and the process skills required for scientific
inquiry and problem solving. Assessment activities should be designed so that learners are assessed on their use of
scientific inquiry skills, like planning, observing and gathering information, comprehending, synthesising, generalising,
hypothesising and communicating results and conclusions. Practical investigations should assess performance at
different cognitive levels and focus on process skills, critical thinking, scientific reasoning and strategies to investigate
and solve problems in a variety of scientific, technological, environmental and everyday contexts.
The difference between a practical investigation and an experiment is that an experiment is conducted to verify or test a
known theory, whereas an investigation is an experiment that is conducted to test a hypothesis, i.e. the result or outcome
is not known beforehand.
4.3.3 Projects
A project is an integrated assessment task that focuses on process skills, critical thinking and scientific reasoning, as
well as strategies to investigate and solve problems in a variety of scientific, technological, environmental and everyday
contexts. This requires a learner to follow the scientific method to produce either a device or a model, or to conduct a
practical investigation.
A project will entail only one of the following:
(i) Construction of a device e.g. electric motor.
(ii) Building a physical model in order to solve a challenge you have identified using concepts in the FET Technical
Sciences curriculum.
(iii) Practical investigation.
Note:
CAPS
TECHNICAL SCIENCES
57
The learner has the option to include a poster as part of the presentation of his/her project. The assessment tools used,
specifying the assessment criteria for each task, will be dictated by the nature of the task and the focus of assessment.
Assessment tools could be one or a combination of rubrics, checklists, observation schedules and memoranda.
REQUIREMENTS FOR GRADE 10, 11 AND 12 PRACTICAL WORK
In Grades 10 and 11 learners will do FOUR prescribed experiments for formal assessment and ONE project. This gives
a total of FIVE formal assessments in practical work in Physical Sciences in each of Grades 10 and 11.
In Grades 10 and 11 it is recommended that learners do TEN experiments for informal assessment. This gives a total of
FIFTEEN assessments in practical work in Technical Sciences in each of Grades 10 and 11.
In Grade 12 learners will do THREE prescribed experiments for formal assessment and one project. This gives a total
of FOUR assessments in practical work in Technical Sciences in Grade 12.
In Grade 12 it is recommended that learners do FIVE experiments for informal assessment. This gives a total of FIVE
informal assessments in practical work in Technical Sciences in Grade 12.

CURRICULUM AND ASSESSMENT POLICY STATEMENT (CAPS)
4.5
Recording and reporting
Recording is a process in which the teacher documents the level of a learner’s performance in a specific assessment
task. It indicates learner progress towards the achievement of the knowledge and skills as prescribed in the Curriculum
and Assessment Policy Statements. Records of learner performance should provide evidence of the learner’s conceptual
progression within a grade and her/his readiness to progress or be promoted to the next grade.
Records of learner performance should also be used to verify the progress made by teachers and learners in the
teaching and learning process.
Reporting is a process of communicating learner performance to learners, parents, schools and other stakeholders.
Learner performance can be reported in a number of ways. These include report cards, parents’ meetings, school
visitation days, parent-teacher conferences, phone calls, letters, class or school newsletters, etc. Teachers in all grades
report in percentages against the subject.
4.5.1 Recording and reporting in the first, second and third terms
Schools are required to provide quarterly feedback to parents on the Programme of Assessment using a formal reporting
tool such as a report card. The schedule and the report card should indicate the overall level of performance of a learner.
Schools should use the following weighting for reporting purposes only and only in the first, second and third terms
of Grades 10, 11 and 12:

4.5.2 Recording and reporting on the Assessment Tasks and SBA in the Programme of Assessment
Schools are also required to provide quarterly feedback to parents and learners of the marks obtained by learners in the
assessment tasks as given.
4.5.3 Recording and reporting at the end of the academic year
The weighting of tasks in the Programme of Assessment must be strictly adhered to when calculating the final mark of
the learner for promotion purposes in each of Grades 10, 11 and 12, at the end of the academic year.
4.6 Moderation of Assessment
4.6.1 SBA
Moderation refers to the process that ensures that the assessment tasks are fair, valid and reliable. Moderation should
be implemented at school, district, provincial and national levels. Comprehensive and appropriate moderation practices
must be in place for the quality assurance of all subject assessments.
All Grade 10 and 11 tasks are internally moderated. The subject head or head of department for Technical Sciences at
the school will generally manage this process.
All Grade 12 tasks should be externally moderated. The subject head or head of department for Technical Sciences at
the school will generally manage this process.
CAPS
TECHNICAL SCIENCES
61
4.6.2PAT
The final phase of the PAT (both project and experiments) will be assessed by the teacher and externally moderated by
the Provincial subject specialist, for Grade 12 only. Each Province will set out dates for external moderation. Learners
will be selected randomly to demonstrate skills from PAT (both project and experiments).
