GUIDELINES FOR THE USE OF ANA EXEMPLARS

1. General overview

The Annual National Assessment (ANA) is a summative assessment of the knowledge and skills that
learners are expected to have developed by the end of each of the Grades 1 to 6 and 9. To support
their school-based assessments and also ensure that learners gain the necessary confidence to
participate with success in external assessments, panels of educators and subject specialists
developed exemplar test questions that teachers can use in their Language and Mathematics lessons.
The exemplar test questions were developed from curriculum work that covers Terms 1, 2 and 3 of the
school year and a complete ANA model test for each grade has been provided. The exemplars, which
include the ANA model test, supplement the school-based assessments that learners must undergo on
a continuous basis and do not replace them.
2. The structure of exemplar questions

The exemplars are designed to illustrate different techniques or styles of assessing the same skills
and/or knowledge. For instance, some content knowledge or a skill can be assessed through a
multiple-choice question (where learners select the best answer from the given options) or a statement
(that requires learners to write a short answer or a paragraph) or other types of questions (asking
learners to join given words/statements with lines, to complete given sentences or patterns, to show
their answers with drawings or sketches, etc.). So, if teachers and learners find a number of exemplar
questions that are structured differently but are asking the same thing, they should understand that this
is deliberate and learners must respond to all the exemplar questions. Exposure to a wide variety of
questioning techniques or styles gives learners the necessary confidence to confront tests.

3. Links with other learning and teaching resource materials

For the necessary integration, some of the exemplar texts and questions have been deliberately linked
to the grade-relevant workbooks. The exemplars have also been aligned with the requirements of the
National Curriculum Statement Grades R to 12 (NCS), the provisions of the Curriculum and
Assessment Policy Statements (CAPS) for the relevant grades and the National Protocol for
Assessment. Together these documents, plus any others that a school may provide, make up a rich
resource base to help teachers in planning lessons and conducting formal assessment (assessment of
learning).
4. How to use the exemplars

While the exemplars for a grade and a subject have been compiled into one comprehensive set, the
teacher does not have to give the whole set to the learners to respond to in one sitting. The teacher
should select exemplar questions that are relevant to the planned lesson at any given time. Carefully
selected individual exemplar test questions, or a manageable group of questions, can be used at
different stages of the teaching and learning process as follows:
4.1   At the beginning of a lesson as a diagnostic test to identify learner strengths and weaknesses.
      The diagnosis must lead to prompt feedback to learners and the development of appropriate
      lessons that address the identified weaknesses and consolidate the strengths. The diagnostic
      test could be given as homework to save time for instruction in class.

                                                                                                       1

4.2   During the lesson as short formative tests to assess whether learners are developing the
      intended knowledge and skills as the lesson progresses and ensure that no learner is left behind.
4.3   At the completion of a lesson or series of lessons as a summative test to assess if the learners
      have gained adequate understanding and can apply the knowledge and skills acquired in the
      completed lesson(s). Feedback to learners must then be given promptly while the teacher
      decides on whether there are areas of the lesson(s) that need to be revisited to consolidate
      particular knowledge and skills.
4.4   At all stages to expose learners to different techniques of assessing or questioning, e.g. how to
      answer multiple-choice (MC) questions, open-ended (OE) or free-response (FR) questions,
      short-answer questions, etc.
While diagnostic and formative tests may be shorter in terms of the number of questions included, the
summative test will include relatively more questions up to a full test depending on the work that has
been covered at a particular point in time. The important thing is to ensure that learners eventually get
sufficient practice in responding to full tests of the type of the ANA model test.
5. Memoranda or answering guidelines

A typical example of the expected response (memorandum) has been given for each exemplar test
question and for the ANA model test. Teachers must bear in mind that the memoranda can in no way
be exhaustive. Memoranda can only provide broad principles of expected responses and teachers must
interrogate and reward acceptable options and variations of the acceptable response(s) given by
learners.
6. Curriculum coverage

It is extremely critical that the curriculum must be covered in full in every class. The exemplars for each
grade and subject do not represent the entire curriculum. They merely sample important knowledge
and skills and only for work that covers terms 1, 2 and 3 of the school year. The pacing of work to be
covered according to the school terms is specified in the relevant CAPS documents.
7. Conclusion

The goal of the Department is to improve the levels and quality of learner performance in the critical
foundational skills of literacy and numeracy. ANA is one instrument the Department uses to monitor
whether learner performance is improving, staying the same or declining. Districts and schools are
expected to support teachers and provide necessary resources to improve the effectiveness of teaching
and learning in the schools. By using the ANA exemplars as part of their teaching resources, teachers
will help learners become familiar with different styles and techniques of assessing. With proper use the
exemplars should help learners acquire appropriate knowledge and develop relevant skills to learn
effectively and perform better in subsequent ANA tests.
