• Resumen

  • A model is proposed based on the statistical concept of the overlapping distribution method (ODM). The model is thenapplied to estimatethe number of students thatcan beexpected to qualify for and to passsupplementaryexaminations.TheODM prediction model was validated using 19 sets of examination events involving 858 civil engineering students in twodifferent universities. It was found that lowering the mark cut-off criteria from 45 to 40%, increases the number of studentsthat qualify for supplementary examinations, by up to 75%. In turn, the number of students that successfully sit forsupplementary examinations, increases by about 40%. The proposed model promises to be useful in informing policy onconflicting issues that arise from balancing the work load under large class sizes on one hand, and offering wideropportunity to as many students as have the potential to pass
