In the mid-1980’s institutions of higher learning were coerced by the South African government to admit students from all races. As a result, these institutions were confronted with the need to identify preparedness for higher learning, especially amongst the ex-Department of Education and Training (DET) learners. Grade 12 results were not a sufficient predictor for ex-DET learners, and a review of current admission criteria became a necessity. This study aims to develop a suitable science entry-level test to be used as a component of an existing test battery. The test battery is used as an admission tool by the Port Elizabeth Technikon to further assess first year applicants who do not meet the normal entrance requirements for a science course. The only requirement for further assessment being Grade 12 physical science. The science entry-level test consists of a list of validated science skills and knowledge to be used to assess the skills and knowledge mastered at the time of test taking. On the basis of test scores, an assessment is made regarding the applicant’s preparedness for higher learning. This study holds the view that preparedness in students for higher learning in science can be measured by means of valid science competencies. In addition, knowledge of the level of preparedness of the applicant enables further educational support and guidance to be provided where necessary. Research which measures manifest academic ability rather than potential to learn is favoured since it is believed that the former generates psychometric evidence of that which was already mastered academically whilst the latter determines whether the student will be able to achieve under ideal conditions. The content covered by the proposed Science Competency Test was sanctioned by technikon lecturers of first year physics and chemistry courses. The content was taken from the examinable section of the Grade 11 and 12 physical science syllabi. This content is the most acceptable and fair knowledge-base a prospective science student can be expected to have mastered at school. The content was limited to those skills and knowledge believed by the lecturers to contribute to academic success in the first year. Items that tested this content were compiled and pilot tests were administered to Grade 12 physical science learners at various disadvantaged schools. The Science Competency Test was compiled from the pool of trial items after the performance of the items was statistically determined. This final Science Competency Test was completed by a sample of 179 first-time first year science students. The findings of the study were inconclusive as the Science Competency Test showed a moderate predictive ability for only one section of the sample. It further showed that the weighted matric score, WMS was not a significant predictor of future academic performance of the sample either. A discrepancy in performance amongst learners of different home languages and educational backgrounds was also noted.
