The VASSI Mathematics Proficiency Test
is a South African assessment tool that was developed for English, Afrikaans and
previously disadvantaged learners. The test is standardised for English,
Afrikaans and Sesothospeaking learners in the foundation phase (Grades 13)
and intermediate phase (Grades 46).
The VASSI Mathematics Proficiency Tests was developed by Dr Colleen Vassiliou.
Dr Vassiliou was a mathematics teacher before studying further as a
psychologist. Due to the problems she encountered as a mathematics teacher and
due to the absence of mathematical proficiency testing she decided to develop
the VASSI Mathematics Proficiency Test.
The first task in helping a learner who is struggling with mathematics is to identify the problem. Thus, if a learner fails to meet the expectations of the curriculum or fails to carry out the cognitive processes
necessary for successful task completion, the VASSI Mathematics Proficiency Test can be used to identify and address this problem.
Users:

Educators of Grade 1 to Grade 6 learners 

Remedial teachers 

Psychologists

The VASSI Mathematics Proficiency Test:

Determines whether a learner has a problem in Mathematics, in which learning
area the problem lay and what cognitive processes need to be stimulated to
assist the learner to cope with the necessary mathematics tasks that are
expected


Can be administered to groups of learners or to individuals


Is standardised for English, Afrikaans and Sesothospeaking learners from
Grade 1 to Grade 6. During standardisation, separate norms for each term were
calculated. These norms are available in both stanines and percentile ranks


The answer sheets are available in English, Afrikaans and Sesotho


Can also be used qualitatively to determine not only the learning strand in
which the learner may be experiencing problems, but also the specific cognitive
process, such as receiving, interpreting, organizing, applying, remembering and
problem solving, which might be preventing the learner from reaching his or her
full mathematical potential 

Is bias free and culturally friendly. During the construction of this test,
care was taken to ensure that the test was crossculturally adapted.
Differential Item Functioning was used to limit the possibility of cultural
bias. The Item Response Theory and the Classical Test Theory were also used for
item analysis and selection


Is a reliable and valid measuring instrument since the bias of the assessment
measure has been decreased. This was done by eliminating any item that was
biased towards a specific cultural group. The test can therefore be used in
practice with confidence 
Necessary training or workshops can be arranged (depending on the size of the
group that is interested in the material)
