Selection as contract to teach at the student's level. Experiences from a South African mathematics and science foundation year

The selection of students is a critical issuecurrently facing South African higher educationinstitutions. The identification and selection ofdisadvantaged students with the potential to succeedin mathematics- and science-based study is aparticularly pressing problem. The new South Africanhigher education law requires that selection is donein a fair and transparent manner. Selection has to befollowed by adequate support for selected students tosucceed in their study programmes. Issues of accessare closely coupled to issues of retention andsuccess. The research results discussed in this paperillustrate how these issues can be successfullyaddressed and how selection fairness and effectivenessmay be optimised under the constraints of selectionefficiency. An optimal solution can be found bydeveloping test specifications and selection cut-offvalues based on the teaching programme for which theselection is done. The resulting close fit betweenselection testing and teaching after selection leadsto a reasonable expectation of success for selectedstudents in the study programme. Under suchconditions, selection can be seen as a contract toteach at the student's level.
